CEikColumnListBox Class Reference

This method needs to be called to enable extended drawing features such as skinning, pictograph drawing and marquee text in the listbox draw routine.

Methods CEikFormattedCellListBox::ConstructL and CEikFormattedCellListBox::ConstructFromResourceL call this method. So, you only need to call this if your listbox implementation does not call either of those.

This method can be safely called more than once. Item drawer must be created before calling this method, or a panic is raised.

Enables/disables list stretching. When a column list is stretched its layout is optimized to take advantage of the extra screen space. This is intented for devices with a large screen. This feature might be set as default by a product specific flag.

Item drawer must be created before calling this method.

From CEikListBox

Handles focus changes.

The function emphasises or de-emphasises the view as needed, and shows or hides the matcher cursor.

From CCoeControl.

Not used in S60 Gets the list of logical colors employed in the drawing of the control, paired with an explanation of how they are used. Appends the list to aColorUseList.

From CCoeControl.

Handles pointer events.

This function gets called whenever a pointer event occurs in the control, i.e. when the pointer is within the control's extent, or when the control has grabbed the pointer. The control should implement this function to handle pointer events.

Note: events of type EButton1Down are processed before HandlePointerEventL() is called, in order to transfer keyboard focus to the control in which the EButton1Down event occurred.

If overriding HandlePointerEventL(), the implementation must include a base call to CCoeControl's HandlePointerEventL().

From CCoeControl.

Handles a change to the control's resources.

The types of resources handled are those which are shared across the environment, e.g. colours or fonts. For colour scheme changes, DrawDeferred() is called in order to redraw the control.

If overriding HandleResourceChange(), the implementation must include a base call to CCoeControl's HandleResourceChange().

Handles a change to the control's resources of type aType which are shared across the environment, e.g. colors or fonts.

Gets the object used by this list box to draw its items.

From CEikListBox.

Creates the list box view. The function is called by @ ConstructL() to create an instance of the appropriate list box view class for this list box. The returned instance is owned by this object, and does not have to have its second-phase constructor run. This function is called by CreateViewL().

Gets the list box model.

From CCoeControl.

Retrieves an object of the same type as that encapsulated in aId.

This function is used to allow controls to ask their owners for access to other objects that they own.

Other than in the case where NULL is returned, the object returned must be of the same object type - that is, the ETypeId member of the object pointed to by the pointer returned by this function must be equal to the iUid member of aUid.
