Detailed Description

Field gadget class.

Library: dbgadget

The IliAbstractComboBox abstract class is intended to serve as a base class for combo box fields such as IliTableComboBox. An IliAbstractComboBox consists of a text field with a button immediately to its right. If editing is allowed, you can edit the value directly in the text field. Alternatively, the button may be used to access either a pull-down menu of multiple choices, or a dialog box to edit the value in a more structured way. A shortcut key also allows you to rapidly activate the button (by default F4).

Note that this class does not define what happens when the user clicks on the button. It is assumed that each subclass of IliAbstractComboBox will behave in a specific manner. For instance, when you click on the button in the IliTableComboBox class, a pull-down menu, containing the foreign table of the field, is opened.

See also: liDialogComboBox, IliTableComboBox.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass IliEntryField.

Constructor & Destructor Documentation

§ IliAbstractComboBox()

IliAbstractComboBox::IliAbstractComboBox	(	IlvDisplay *	display,
		const IlvRect &	rect,
		IlUShort	thickness = `IlvDefaultGadgetThickness`,
		IlvPalette *	palette = `0`
	)

protected

Initializes a new abstract combo box.

Parameters

display	The display.
rect	The location.
thickness	The border thickness.
palette	The palette.

Member Function Documentation

§ allowEdit()

void IliAbstractComboBox::allowEdit ( IlBoolean enable )

Specifies whether editing is allowed for the abstract combo box.

Parameters

enable The editing state: enable (IlTrue)/disable (IlFalse).

§ close()

virtual void IliAbstractComboBox::close ( )

virtual

Hides the pull-down menu or dialog box.

The type of object that is hidden depends on the subclass of IliAbstractComboBox being used.

Reimplemented in IliTableComboBox, and IliDialogComboBox.

§ CloseSymbol()

static IlvSymbol* IliAbstractComboBox::CloseSymbol ( )

static

Returns the symbol name of the Close callback.

Returns: The symbol.

§ f_isReadOnly()

virtual IlBoolean IliAbstractComboBox::f_isReadOnly ( ) const

virtual

Returns IlTrue if the field is read-only.

Returns: IlTrue if the field is read-only.

Reimplemented from IliEntryField.

§ f_setReadOnly()

virtual void IliAbstractComboBox::f_setReadOnly ( IlBoolean flag )

virtual

Sets the read-only property for the field.

Parameters

flag	The read-only flag.

Reimplemented from IliEntryField.

§ GetOpenShortCut()

static void IliAbstractComboBox::GetOpenShortCut	(	IlUShort &	modifiers,
		IlUShort &	key
	)

static

Returns the definition of the shortcut key that causes the pull-down menu or dialog box to be displayed.

The default for this property is the F4 key.

Parameters

modifiers	The modifiers.
key	The key

Returns: The shortcut key.

§ isArrowShown()

IlBoolean IliAbstractComboBox::isArrowShown ( ) const

Returns IlTrue if the button is shown.

Initially, this property is IlTrue. When the button is not shown, the gadget looks like a text field.

Returns: The visibility.

§ isEditAllowed()

IlBoolean IliAbstractComboBox::isEditAllowed ( ) const

Returns IlTrue if editing is allowed for the abstract combo box.

This property should not be confused with the read-only property obtained with the f_isReadOnly() member function. An abstract combo box may inhibit editing without being read-only. This is because editing, in this situation, only refers to the text field part of the abstract combo box. Therefore, though editing may be inhibited, you are still able to change the value for the gadget using the pull-down menu or dialog box.

Returns: The editing rights flag.

§ isOpen()

virtual IlBoolean IliAbstractComboBox::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 in IliTableComboBox, and IliDialogComboBox.

§ onClose()

virtual void IliAbstractComboBox::onClose ( )

virtual

Called just after the pull-down menu or the dialog box is dismissed.

By default, the Close callback is called.

§ onOpen()

virtual void IliAbstractComboBox::onOpen ( )

virtual

Called just before the pull-down menu or the dialog box is displayed.

By default, the Open callback is called.

§ open()

virtual void IliAbstractComboBox::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

grab	Reserved for future use and its value must always be `IlFalse`.

Reimplemented in IliDialogComboBox.

§ OpenSymbol()

static IlvSymbol* IliAbstractComboBox::OpenSymbol ( )

static

Returns the symbol name of the Open callback.

Returns: The symbol.

§ SetOpenShortCut()

static void IliAbstractComboBox::SetOpenShortCut	(	IlUShort	modifiers,
		IlUShort	key
	)

static

Defines the shortcut key that causes the pull-down menu or dialog box to be displayed.

If key has a value of 0, no shortcut key is defined.

Parameters

modifiers	The modifiers.
key	The key.

§ showArrow()

void IliAbstractComboBox::showArrow ( IlBoolean show )

Shows or hides the arrow button.

Parameters

show	If `IlTrue`, the button is visible otherwise (`IlFalse`) the button is not visible.
