9.0 User Interface Tips
[9.1] Use icons in toolbars
Custom toolbar titles and labels are usually text. It is an undocumented feature of the 89/92+ that you
can also use small graphics (icons) in place of the toolbar titles and labels. This code extract shows the
method:
circ()
Prgm
ClrIO
Toolbar
Title circimg
Item radimg,r
Item areaimg,a
Item circimg,c
EndTBar
Lbl r
...
Lbl a
...
Lbl c
...
EndPrgm
In this example, the icons are the variables circimg, radimg, and areaimg. Note that the icon circimg is
used in both the toolbar title, and in the third menu item. The icons are PIC variables, 16 pixels high by
16 pixels wide.
The icons can be created in a number of ways. You can use the pixel functions: PxlCrcl, PxlLine,
PxlOn and PxlText in a program to create the image, then use StoPic to save the image. This program
creates an icon, and saves it as icon1.
