TCustomPanel.UpdateParentColorChange procedure

Declaration

procedure UpdateParentColorChange

Description

UpdateParentColorChange updates the control to use the opacity needed for the values in the ParentColor or ParentBackground properties.

If either ParentColor or ParentBackground is True, the value csOpaque is excluded from the ControlStyle property. If both properties are False, csOpaque is included in the ControlStyle property.

UpdateParentColorChange is called from the Loaded method when the component has finished loading using the LCL component streaming mechanism. It is called from the CMParentColorChanged method when the change message is handled for the control. It is also called when a new value is assigned to the ParentColor or ParentBackground properties.
