TButtonGlyph.NumGlyphs property
The number of glyphs available for button states.
Declaration
property NumGlyphs: TNumGlyphs read GetNumGlyphs write SetNumGlyphs;Description
NumGlyphs is a
TNumGlyphs property which indicates the
number of glyphs available for its button states. The default value for the
property is
1 (the low value for the range), and indicates that a
single image is used for all button states in the
TButtonGlyph.
The value in NumGlyphs is updated when a TBitmap
instance is directly assigned to the Glyph property, and when
GetImageIndexAndEffect retrieves the Images and drawing effect(s)
for a given display density (PPI).
Reading the value in NumGlyphs causes the
ExternalImages property to be examined; when it is assigned, the
value for the property is always 1 (corresponding to the
ExternalImageIndex). Otherwise, the value in the internal member
is used.
Changing the value in NumGlyphs causes the Refresh
method to be called.
