Detailed Description

A dialog base class with standard buttons and predefined layouts.

Provides basic functionality needed by nearly all dialogs.

It offers the standard action buttons you'd expect to find in a dialog as well as the capability to define at most three configurable buttons. You can define a main widget that contains your specific dialog layout or you can use a predefined layout. Currently, TreeList/Paged, Tabbed, Plain, Swallow and IconList mode layouts (faces) are available.

The class takes care of the geometry management. You only need to define a minimum size for the widget you want to use as the main widget.

You can set a background tile (pixmap) for parts of the dialog. The tile you select is shared by all instances of this class in your application so that they all get the same look and feel.

There is a tutorial available on http://developer.kde.org/ (NOT YET) that contains copy/paste examples as well a screenshots on how to use this class.

@sect Standard buttons (action buttons):

You select which buttons should be displayed, but you do not choose the order in which they are displayed. This ensures a standard interface in KDE. The button order can be changed, but this ability is only available for a central KDE control tool. The following buttons are available: OK, Cancel/Close, Apply/Try, Default, Help and three user definable buttons: User1, User1 and User3. You must specify the text of the UserN buttons. Each button has a virtual slot so you can overload the method when required. The default slots emit a signal as well, so you can choose to connect a signal instead of overriding the slot. The default implementation of slotHelp() will automatically enable the help system if you have provided a path to the help text. slotCancel() and slotClose() will run QDialog::reject() while slotOk() will run QDialog::accept(). You define a default button in the constructor.

If you don't want any buttons at all because your dialog is special in some way, then set the buttonMask argument in the constructor to zero (0). The optional button box separator line should not be enabled in this case. Note that the KDialogBase will animate a button press when the user press Escape. The button that is enabled is either Cancel, Close or the button that is defined by setEscapeButton() The animation will not take place when the buttonMask is zero. Your custom dialog code should reimplement the keyPressEvent and animate the cancel button so that the dialog behaves like regular dialogs. NOTE: None of the regular slots (like slotOk() ) or signals that are related to the standard action buttons will be used when you don't use these buttons.

@sect Dialog shapes:

You can either use one of the prebuilt, easy to use, faces or define your own main widget. The dialog provides ready to use TreeList, Tabbed, Plain, Swallow and IconList faces. KDialogBase uses the KJanusWidget class internally to accomplish this. If you use TreeList, Tabbed or IconList mode, then add pages with addPage().

Pages that have been added can be removed again by simply deleting the page.

If you want complete control of how the dialog contents should look, then you can define a main widget by using setMainWidget(). You only need to set the minimum size of that widget and the dialog will resize itself to fit this minimum size. The dialog is resizeable, but cannot be made smaller than its minimum size.

@sect Layout:

The dialog consists of a help area on top (becomes visible if you define a help path and use enableLinkedHelp()), the main area which is the built-in dialog face or your own widget in the middle and by default a button box at the bottom. The button box can also be placed at the right edge (to the right of the main widget). Use setButtonBoxOrientation() to control this behavior. A separator can be placed above the button box (or to the left when the button box is at the right edge). Normally you specify that you want a separator in the constructor, but you can use enableButtonSeparator() as well.

@sect Standard compliance:

The class is derived from KDialog, so you get automatic access to the KDialog::marginHint(), KDialog::spacingHint() and the extended KDialog::setCaption() method. NOTE: The main widget you use will be positioned inside the dialog using a margin (or border) equal to KDialog::marginHint(). You shall not add a margin yourself. The example below (from kedit) shows how you use the top level widget and its layout. The second argument (the border) to QVBoxLayout is 0. This situation is valid for addPage , addVBoxPage , addHBoxPage , addGridPage , makeMainWidget , makeVBoxMainWidget , makeHBoxMainWidget and makeGridMainWidget as well.

Example: 

 UrlDlg::UrlDlg( QWidget *parent, const QString& caption,
                 const QString& urltext)
   : KDialogBase( parent, "urldialog", true, caption,
		    KDialogBase::Ok|KDialogBase::Cancel, KDialogBase::Ok, true )
 {
   QWidget *page = new QWidget( this );
   setMainWidget(page);
   QVBoxLayout *topLayout = new QVBoxLayout( page, 0, spacingHint() );

   QLabel *label = new QLabel( caption, page, "caption" );
   topLayout->addWidget( label );

   lineedit = new QLineEdit( urltext, page, "lineedit" );
   lineedit->setMinimumWidth(fontMetrics().maxWidth()*20);
   topLayout->addWidget( lineedit );

   topLayout->addStretch(10);
 }

If you use makeVBoxMainWidget(), then the dialog above can be made simpler but you lose the ability to add a stretchable area: 

 UrlDlg::UrlDlg( QWidget *parent, const QString& caption,
		const QString& urltext)
 : KDialogBase( parent, "urldialog", true, caption,
		  KDialogBase::Ok|KDialogBase::Cancel, KDialogBase::Ok, true )
 {
   QVBox *page = makeVBoxMainWidget();
   QLabel *label = new QLabel( caption, page, "caption" );

   lineedit = new QLineEdit( urltext, page, "lineedit" );
   lineedit->setMinimumWidth(fontMetrics().maxWidth()*20);
 }

This class can be used in many ways. Note that most KDE ui widgets and many of KDE core applications use the KDialogBase so for more inspiration you should study the code for these.

Member Function Documentation

void KDialogBase::aboutToShowDetails (    )  [signal]
 

The detailsWidget is about to get shown. This is your last chance to call setDetailsWidget if you haven't done so yet.

void KDialogBase::aboutToShowPage (  QWidget *    page )  [signal]
 

A page is about to be shown.

QPushButton* KDialogBase::actionButton (  ButtonCode    id ) 
 

Returns the action button that corresponds to the id.

Normally you should not use this function. Never delete the object returned by this function. See also enableButton(), showButton(), setButtonTip(), setButtonWhatsThis(), and setButtonText().

Parameters:
id  Integer identifier of the button.
Returns:
The action button or 0 if the button does not exists.

int KDialogBase::activePageIndex (    ) 
 

Returns the index of the active page.

This method will only work when the dialog is using the predefined shape of Tabbed, TreeList or IconList.

Returns:
The page index or -1 if there is no active page.

QGrid* KDialogBase::addGridPage (  int    n,
Orientation    dir,
const QStringList &    items,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

This is like addGridPage() just above, with the difference that the first element is a list of strings.

These strings are used to form a path of folders down to the given page. The initial elements are names for the folders, while the last element is the name of the page. Note: This does yet only work for the TreeList face. Later this may be added for the IconList face too. In other faces than the TreeList, all the strings except the last one is ignored.

QGrid* KDialogBase::addGridPage (  int    n,
Orientation    dir,
const QString &    itemName,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

Add a page to the dialog when the class is used in TreeList, IconList or Tabbed mode.

The returned widget must be used as the toplevel widget for this particular page. The widget contains a QGridLayout layout so the widget children are positioned in a grid.

Parameters:
n  Specifies the number of columns if dir is Qt::Horizontal or the number of rows if dir is Qt::Vertical.
dir  Can be Qt::Horizontal or Qt::Vertical.
itemName  String used in the list or as tab item name.
header  Header text use in the list modes Ignored in Tabbed mode. If empty, the item text is used instead.
pixmap  Used in IconList mode. You should prefer a pixmap with size 32x32 pixels.
Returns:
The page widget which must be used as the toplevel widget for the page.

QHBox* KDialogBase::addHBoxPage (  const QStringList &    items,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

This is like addHBoxPage() just above, with the difference that the first element is a list of strings.

These strings are used to form a path of folders down to the given page. The initial elements are names for the folders, while the last element is the name of the page. Note: This does yet only work for the TreeList face. Later this may be added for the IconList face too. In other faces than the TreeList, all the strings except the last one is ignored.

QHBox* KDialogBase::addHBoxPage (  const QString &    itemName,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

Add a page to the dialog when the class is used in TreeList, IconList or Tabbed mode.

The returned widget must be used as the toplevel widget for this particular page. The widget contains a QHBoxLayout layout so the widget children are lined up horizontally. You can use it as follows:

Parameters:
itemName  String used in the list or as tab item name.
header  Header text use in the list modes. Ignored in Tabbed mode. If empty, the item text is used instead.
pixmap  Used in IconList mode. You should prefer a pixmap with size 32x32 pixels.
Returns:
The page widget which must be used as the toplevel widget for the page.

QFrame* KDialogBase::addPage (  const QStringList &    items,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

This is like addPage() just above, with the difference that the first element is a list of strings.

These strings are used to form a path of folders down to the given page. The initial elements are names for the folders, while the last element is the name of the page. Note: This does yet only work for the TreeList face. Later this may be added for the IconList face too. In other faces than the TreeList, all the strings except the last one is ignored.

QFrame* KDialogBase::addPage (  const QString &    itemName,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

Add a page to the dialog when the class is used in TreeList , IconList or Tabbed mode.

The returned widget must be used as the toplevel widget for this particular page. Note: The returned frame widget has no layout manager associated with it. In order to use it you must create a layout yourself as the example below illustrates: 

 QFrame *page = addPage( i18n("Layout") );
 QVBoxLayout *topLayout = new QVBoxLayout( page, 0, 6 );
 QLabel *label = new QLabel( i18n("Layout type"), page );
 topLayout->addWidget( label );
 ..
Parameters:
itemName  String used in the list or as tab item name.
header  Header text use in the list modes. Ignored in Tabbed mode. If empty, the item text is used instead.
pixmap  Used in IconList mode. You should prefer a pixmap with size 32x32 pixels.
Returns:
The page widget which must be used as the toplevel widget for the page.

QVBox* KDialogBase::addVBoxPage (  const QStringList &    items,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

This is like addVBoxPage() just above, with the difference that the first element is a list of strings.

These strings are used to form a path of folders down to the given page. The initial elements are names for the folders, while the last element is the name of the page. Note: This does yet only work for the TreeList face. Later this may be added for the IconList face too. In other faces than the TreeList, all the strings except the last one is ignored.

QVBox* KDialogBase::addVBoxPage (  const QString &    itemName,
const QString &    header = QString::null,
const QPixmap &    pixmap = QPixmap()
) 
 

Add a page to the dialog when the class is used in TreeList, IconList or Tabbed mode.

The returned widget must be used as the toplevel widget for this particular page. The widget contains a QVBoxLayout layout so the widget children are lined up vertically. You can use it as follows: 

 QVBox *page = addVBoxPage( i18n("Layout") );
 QLabel *label = new QLabel( i18n("Layout type"), page );
 ..
Parameters:
itemName  String used in the list or as tab item name.
header  Header text use in the list modes. Ignored in Tabbed mode. If empty, the item text is used instead.
pixmap  Used in IconList mode. You should prefer a pixmap with size 32x32 pixels.
Returns:
The page widget which must be used as the toplevel widget for the page.

virtual void KDialogBase::adjustSize (    )  [virtual]
 

Adjust the size of the dialog to fit the contents just before QDialog::exec() or QDialog::show() is called.

This method will not be called if the dialog has been explicitly resized before showing it.

void KDialogBase::apply (    )  [signal]
 

Do not use this signal. Is is kept for compatibility reasons. Use applyClicked() instead.

void KDialogBase::applyClicked (    )  [signal]
 

The Apply button was pressed. This signal is only emitted if slotApply() is not replaced.

virtual void KDialogBase::applyPressed (    )  [protected, virtual, slot]
 

Do not use this slot. Is is kept for compatibility reasons. Activated when the Apply button has been clicked

void KDialogBase::backgroundChanged (    )  [signal]
 

The background tile has changed.

const QPixmap* KDialogBase::backgroundTile (    )  [static]
 

Returns a pointer to the background tile if there is one.

Returns:
The tile pointer or 0 if no tile is defined.

QSize KDialogBase::calculateSize (  int    w,
int    h
)  const
 

Calculate the size hint for the dialog.

With this method it is easy to calculate a size hint for a dialog derived from KDialogBase if you know the width and height of the elements you add to the widget. The rectangle returned is calculated so that all elements exactly fit into it. Thus, you may set it as a minimum size for the resulting dialog.

You should not need to use this method and never if you use one of the predefined shapes.

Parameters:
w  The width of you special widget.
h  The height of you special widget.
Returns:
The minimum width and height of the dialog using w and h as the size of the main widget.

void KDialogBase::cancel (    )  [slot]
 

Force closing the dialog, setting its result code to the one Esc would set. You shouldn't use this, generally (let the user make his choice!) but it can be useful when you need to make a choice after a timeout has happened, or when the parent widget has to go somewhere else (e.g. html redirections).

Since:
3.1

void KDialogBase::cancelClicked (    )  [signal]
 

The Cancel button was pressed. This signal is only emitted if slotCancel() is not replaced.

void KDialogBase::closeClicked (    )  [signal]
 

The Close button was pressed. This signal is only emitted if slotClose() is not replaced.

virtual void KDialogBase::closeEvent (  QCloseEvent *    e )  [protected, virtual]
 

Detects when a dialog is being closed from the window manager controls. If the Cancel or Close button is present then the button is activated. Otherwise standard QDialog behavior will take place.

QSize KDialogBase::configDialogSize (  const QString &    groupName )  const
 

read the dialogs size from the configuration according to the screen size. If no size is saved for one dimension of the screen, a default size is choosed. The default width is 50 percent of the screen width, the default height is 40 percent of the screen height.

Parameters:
groupName  Name of the group to read from. The old group of KGlobal::config is preserved.

void KDialogBase::defaultClicked (    )  [signal]
 

The Default button was pressed. This signal is only emitted if slotDefault() is not replaced.

void KDialogBase::delayedDestruct (    )  [slot]
 

Destruct the Dialog delayed.

You can call this function from slots like closeClicked() and hidden(). You should not use the dialog any more after calling this function.

Since:
3.1

void KDialogBase::finished (    )  [signal]
 

The dialog has finished.

A dialog emits finished after a user clicks a button that ends the dialog.

This signal is also emitted when you call hide()

If you have stored a pointer to the dialog do not try to delete the pointer in the slot that is connected to this signal.

You should use delayedDestruct() instead.

const QPixmap* KDialogBase::getBackgroundTile (    )  [static]
 

Deprecated:
Use backgroundTile() instead.

void KDialogBase::getBorderWidths (  int &    ulx,
int &    uly,
int &    lrx,
int &    lry
)  const
 

Deprecated:
Do not use this method. It is included for compatibility reasons.

This method returns the border widths in all directions the dialog needs for itself. Respect this, or get bad looking results. The references are upper left x (ulx), upper left y (uly), lower right x (lrx), and lower left y (lly). The results are differences in pixels from the dialogs corners.

QRect KDialogBase::getContentsRect (    ) 
 

Deprecated:
Do not use this method. It is included for compatibility reasons.

This method returns the contents rectangle of the work area. Place your widgets inside this rectangle, and use it to set up their geometry. Be careful: The rectangle is only valid after resizing the dialog, as it is a result of the resizing process. If you need the "overhead" the dialog needs for its elements, use getBorderWidths().
