The IconPopup dialog item can be used to display an icon along with an arrow, which indicates that a drop down box can be displayed containing a ComboBox, Menu, or group of dialog items. The icon portion of the IconPopup can be connected to the arrow or not. If not, the icon portion can be used as a toggle button, with an on/off value, or as a command button.
The icon popup item is defined in a resource file with the following structure:
The DItem_IconPopupRsc structure has the following unique fields. (See "Common Item Resource Fields" for a description of any field not in this table).
