Member variable XbpDialog():clientSize Foundation
Specifies the dimensions of the dialog inner area (drawing area).
Instance variable :clientSize contains an array with two elements that specify the width and height of the XbpDialog's drawing area, respectively. If nothing is passed in parameter <aSize> to either :new() or :create(), the array specified in :clientSize is used to compute the dialog's outer dimensions. This allows to create dialogs sized to fit a certain content area, whereas specifying width and height using the <aSize> parameter causes sizes to vary depending on the window frame settings defined in Control Panel.
