Detailed Description

Field gadget class.

Library: dbgadget

The IliDialogComboBox defines a combo box gadget that opens a dialog box when the user clicks on the button inside the gadget. The button in this combo box gadget shows three dots instead of an arrow. This class serves as a base class for other, more specialized classes, that define precisely which dialog box should be used.

Initially, this property is set to NULL.

Returns
The dialog.
virtual IlBoolean IliDialogComboBox::isOpen ( ) const
virtual

Returns IlTrue if the pull-down menu or the dialog box is currently displayed.

Returns
The pull-down menu (or dialog box) visibility.

Reimplemented from IliAbstractComboBox.

virtual void IliDialogComboBox::onApply ( )
virtual

Called when the dialog interaction with the user is completed, the dialog has been dismissed and when the outcome of the interaction is not a user cancellation.

The default implementation calls the Apply callback.

virtual void IliDialogComboBox::onEndDialog ( )
protectedvirtual

Called just after the dialog interaction with the user is completed and the dialog has been dismissed.

The default implementation does nothing.

virtual void IliDialogComboBox::onInitDialog ( )
protectedvirtual

It sets the dialog properties using the setDialog member function. The default implementation does nothing.

virtual void IliDialogComboBox::open ( IlBoolean  grab)
virtual

Causes a pull-down menu or dialog box to be displayed.

Whether the object displayed is a pull-down menu or a dialog box depends on the subclass of IliAbstractComboBox being used.

Parameters
grabReserved for future use and its value must always be IlFalse.

Reimplemented from IliAbstractComboBox.

void IliDialogComboBox::setDialog ( IlvDialog dlg,
IlBoolean  owner = IlTrue 
)
protected

Sets the dialog of the combo box.

Parameters
dlgThe dialog.
ownerIf IlTrue, the combo box becomes the owner of the dialog.
virtual void IliDialogComboBox::showDialog ( IlBoolean  grab)
protectedvirtual

Called when the dialog needs to be shown.

The default implementation does the following:
