Set Bitmap Scheme
Use this system function to set the default bitmap schema that will be used by the tree nodes in the tree control.
Parameters
- Tree Control
-
Input, required. The tree control FC to affect.
- Open Bitmap
-
Input, required. The bitmap to display for a node when it has been expanded. Set the parameter to a particular bitmap (double-click <Choose Tree Bitmap> to browse for one) or the standard bitmap (<Default>).
- Closed Bitmap
-
Input, required. The bitmap to display for a node when it has been collapsed. Set the parameter to a particular bitmap (double-click <Choose Tree Bitmap> to browse for one) or the standard bitmap (<Default>).
- Leaf Bitmap
-
Input, required. The bitmap to display for a leaf node with no children. Set the parameter to a particular bitmap (double-click <Choose Tree Bitmap> to browse for one) or the standard bitmap (<Default>).
Additional Notes
The bitmaps must be of size 16 x 16 and should reside in the treebmps subdirectory of the resource directory (for example: d:\b7\appl_pgf\res\treebmps). If a bitmap fails to load, the application uses the corresponding standard bitmap. The ideal place for using this system function is during on event, Dialog Is Initialized.
