TCustomBitBtn.Margin property
The space prior to the glyph bitmap on the aligned edge of the button layout.
Declaration
property Margin: Integer read FMargin write SetMargin default - 1;Description
Margin is an
Integer property with the space reserved
prior to the Glyph or image displayed on the button control. It occurs on the
aligned edge specified in Layout, and refers to a number of pixels. The value
-1 has special meaning; it causes the glyph and caption to be centered on the
button surface.
The default value for the property is -1. Changing the property value causes the widgetset class instance to be updated when its handle has been allocated. AdjustSize is called to auto-size a visible control and its parent. At design-time, the Invalidate method is called to redraw the control.
The property value is used in the InitializeWnd method to set the initial value in the widget class.
Use Layout to specify the edge on the button control to which the glyph bitmap and caption are aligned.
Use Spacing to set the space reserved between the glyph bitmap and the caption for the control.
