Description

bCompoundValue:Draw() draws the value with all subordinated values within the specified area. Before the value is drawn, it is transformed into a string with the method bCompoundvalue:Transform().

Values of the type Bitmap or Icon are drawn by the method. For all other values of the type object, the method examines whether in the object is defined a method with the name Draw(). If a method is defined, this is called for drawing. The method is invoked with the following arguments:

<object>:Draw(

<hDC>,

<srcArea>,

<iAlignment>,

<oForeground>,

<oBackground>,

<oFont>,

<lDeleted>,

<lSelected>,

<lEnabled>,

<lCurrent>,

)
