A simple combo box is a text box followed by a list box covering the whole combo area.
A spin box ignores any defined buttons for the combo box skin. The skin of the vertical scroll bar for the application is used to draw the spin box over the top of any defined border.
When the combo box has a text box portion, the text box allows only a solid background color and does not successfully handle any defined brush.
A combo box skin consists of a border definition and a button that is placed on the right side of the border area. The way in which it is painted depends on the defined border, as follows.
-
If the combo box skin has the JadeSkinControl class borderStyle property set to BorderStyle_UseImages, the button image is centered vertically and offset from the right-hand edge of the combo box by the value of the buttonRightOffset property, as shown in the following example.
-
If the combo box skin has the borderStyle property set to a value other than BorderStyle_UseImages, the button is drawn inside whatever border is defined (against right inner edge of the border and stretched vertically), as shown in the following example.
