|---|---|---|---|
| 1 | 1 | **TBitBtn**  is a component that creates a button with a bitmap drawn on its surface. A TBitBtn is a descendant of [[TWinControl]] and is available under the [[Additional tab]] of the [[Component Palette]]. | |
| 2 | 2 | ||
| 3 | 3 | To make usage of standard buttons a bit easier a TBitBtn has a property *Kind* that let you select a buttonkind like *bkOk* to create an \[Ok\] button with text and corresponding picture (accessible as *Glyph* and a modal-result 'mrOk'). | |

| 10 | 7 | Positioning of glyph and caption can be controlled by means of these properties: | |
| 11 | 8 | ||
| 12 | 9 | - `Layout` is an enumeration of `blGlyphLeft`, `blGlyphRight`, `blGlyphTop` and `blGlyphBottom` which determines whether the glyph will be placed at the left, right, above or below the caption, respectively. Default: `blGlyphLeft`. | |
| 13 | 10 | - `Margin` is the distance between the edge of the button and glyph, in pixels. The value -1 means that the combination of glyph and caption is centered within the button. Default: `-1`. | |
| 14 | 11 | - `Spacing` is the distance between the glyph and the caption, in pixels. The value -1 means that the caption is centered between glyph and button edge. If `Margin` is -1, too, then glyph and caption will be equally distributed within the button area. Default: `4`. | |
| 15 | 12 | ||
| 16 | 13 | If you have several vertically stacked BitBtn components (with `Layout=blGlyphLeft`) on a form and want to left-align glyphs and captions set `Margin` and `Spacing` to some positive value, such as 4. | |
