when I change the color of the TEdit control, the SELECTION Color is changed also... to be the same as the edit.color meaning if I set edit.color := clwhite then the selection is drawn as clwhite also. after modifying the edit.color there is no way to make it paint properly again. so effectivly the only way to make sure a TEdit draws correctly is to not edit the edit.color property. |

Interesting to note is that if I use this code to change the color ( instead of TEdit.color := clBlue ) the color change then works as expected. function myAllocGDKColor(const AColor: LongInt): TGDKColor; begin with Result do begin Red := ((AColor shl 8) and $00FF00) or ((AColor ) and $0000FF); Green := ((AColor ) and $00FF00) or ((AColor shr 8 ) and $0000FF); Blue := ((AColor shr 8) and $00FF00) or ((AColor shr 16) and $0000FF); end; gdk_colormap_alloc_color(gdk_colormap_get_system, @Result, False, True); end; procedure set_TextViewColor( aTextView : TCustomEdit; aColor : Tcolor ); var lTextView : PGtkTextView; lGdkColor : TGDKColor; begin lTextView := GTK_TEXT_VIEW( GetWidgetInfo( PGtkWidget( TCustomEdit( aTextView ).Handle ), false )^.CoreWidget ); lGdkColor := myAllocGDKColor( aColor ); gtk_widget_modify_base ( pGtkWidget( lTextView ), GTK_STATE_NORMAL, @lGdkColor); end; |
