Namespace:DevExpress.XtraBars.Ribbon.Gallery
Assembly:DevExpress.XtraBars.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type GalleryItemCustomDrawEventArgs containing data related to this event.

The following GalleryItemCustomDrawEventArgs properties provide information specific to this event.
Property Description
Bounds Gets the bounding rectangle of the Gallery item currently being painted.
Cache Gets an object which specifies the storage for the most used pens, fonts and brushes.
Gallery Gets the Gallery that contains the processed Gallery item.
Handled Gets or sets whether an event was handled. If it was handled default painting isn't required.
InRibbonGalleryLink For In-Ribbon galleries, gets the bar item link that displays the current gallery.
Item Gets the Gallery item currently being processed.
ItemInfo Gets the information which is required to paint a Gallery item.

Expanded Remarks

The CustomDrawItemImage event is raised each time an item's image is about to be painted. The event parameter provides all the information necessary to paint an image. Set the Handled property to true to prohibit default image painting.

Expanded Example

In this example the CustomDrawItemImage event is handled to manually paint item images within the Font Color Gallery. Individual items correspond to specific colors.

The full source code can be found in the 'Ribbon Simple Pad' demo supplied with the XtraBars.
