Declaration

 const AXProportion: Double; 
 const AYProportion: Double); override

Arguments

Description

DoAutoAdjustLayout is an overridden method in TCustomTabControl used to apply the specified auto-adjustment layout policy to the tabbed control. It calls the inherited method on entry to adjust the size, position, and alignment for the control including border spacing.

DoAutoAdjustLayout ensures that the width and height for the tabs and their assigned images are updated when needed. The image list in the widgetset class is updated (when assigned) to use the resolution needed for the PPI setting in Font. Values in TabWidth and TabHeight are adjusted (when assigned) using the scaling factors in AXProportion and AYProportion.

DoAutoAdjustLayout method is called from the DoAutoAdjustLayout method, and occurs when a scaled form (and its controls) are displayed in an application.

Modified in LCL version 3.0 to apply scaling factors to TabWidth and TabHeight.
