Sets the value in the internal Changed flag to True.
Source position: imglist.pp line 316
protected procedure TCustomImageList.MarkAsChanged; |
MarkAsChanged allows an application to set the value for the internal member which tracks whether the image list has been modified. When enabled, the Change method performs change notifications for subscribers and signals the OnChange event handler (when assigned) when the EndUpdate method is called.
MarkAsChanged sets the value for the internal member to True. This update normally occurs in methods like Clear, Delete, Move, ReadData, ReadAdvData, and when the value in BkColor is changed. MarkAsChanged allows descendent classes to set the flag value from any methods added to the class or from application code.
Added in LCL version 3.0.
