Notes

  • BackgroundImage sets the picture and BackgroundFillType how it is laid out (tile, stretch, centre, gradient and so on).
  • For a colour gradient set GradientStartColor and GradientEndColor, with GradientDirection choosing the axis.
  • Transparent lets the form background show through, which is how you divide a picture skin into areas.
  • BorderAlpha fades the border, giving a subtle divider.

Properties of TMlSkinCustomControl 4
NameTypeDefaultDescription
AboutTMlAboutInfoA design-time property: double-clicking it in the Object Inspector opens the MLSkin about box with the component version. It has no effect at run time and is not stored in the .dfm.
TransparentBooleanTrueTransparent background: the control skips its own fill and shows the form background (image or color) instead.
AutoInvalidateBooleanFalseRepaints automatically when the content changes. Turn it on if property changes do not show up.
EraseBackgroundBooleanFalseWhether the background is erased before painting; worth toggling if the control flickers.
