If an XbpBitmap or XbpIcon object is assigned to the :imageinstance variable, one of the methods :load() or :loadFile() must have previously been called. For bitmaps constructed in memory, method :make() must have been used. Moreover, it is discouraged to use the XbpBitmap or XbpIcon object to load or define a different image as long as it is assigned to the treeview item. Instead, a new object should be created for each different image.
Member variable XbpTreeViewItem():image Foundation
Resource ID, XbpBitmap or XbpIcon object of the bitmap or icon which indicates the normal state.
Attribute: EXPORTED
Data type: Numeric | Object (-1)
Description
The resource ID of a BITMAP resource (Windows Bitmap file format) or icon can be assigned to the instance variable :image to visualize the normal state of an XbpTreeViewItem object (not marked and not expanded). Resource IDs must be defined in a resource file which is linked to the EXE file using the resource compiler. Instead of a resource ID, an object of the XbpBitmap or XbpIcon classes can be assigned. Assigning a XbpBitmap object allows the usage of images defined in various image file formats (.BMP/.JPG/.PNG). Furthermore, if a transparent color has been defined for the bitmap object, transparent areas within the image are automatically replaced with the background color defined for the XbpTreeView object.
If method :create() of the tree view item has been executed, assigning a new icon or bitmap :image changes the image displayed by the item. This can be used to change a tree view item's image dynamically while it is being displayed. See method :setImage() for further information.
