Description

CanShow is a Boolean function which indicates if the glyph can be drawn for the button glyph. The return value is determined by examining the value in the ShowMode property. Values in the TGlyphShowMode enumeration determine the return value using the following logic:

gsmAlways
Return value is True
gsmNever
Return value is False
gsmApplication
Uses the Application.ShowButtonGlyphs property to determine the return value
gsmSystem
Uses the value from SystemShowButtonGlyphs as the return value
The return value is always True at design-time.

Use CanShowGlyph to determine if an image is available to be drawn on the button.
