TWinControl.AdjustClientRect

Override this method when the ClientRect for a control differs from the default value.

Declaration

Source position: controls.pp line 2155

Arguments

Description

In TWinControl, the virtual method has an empty implementation. It can be overridden in descendent classes to perform actions needed for the class type. Such as:

• Shrink or grow the client rectangle to account for added or removed borders or bezels.
• Reserve space for companion controls or user interface elements.
• Set state or configuration flags which affect the client rectangle for the class.

AdjustClientRect can be called often, especially during auto-sizing and anchoring operations. Do not use expensive code here, or cache the resulting client rectangle for subsequent access.

Version info

Behavior modified in LCL version 3.4 to use the adjusted client rectangle when controls are aligned.
