FabDev 8 Posted January 21, 2022 Hello, Like described here : How to set tab stops in a TMemo In a TMemo in VCL it's possible to set the tab width using such a code : Memo1.Perform( EM_SETTABSTOPS, 1, LongInt(@lTabWidth)); or SendMessage(Memo1.handled, EM_SETTABSTOPS, 1, Longint(@lTabWidth)); But does it exist a way to do the same on FMX ? Because if have tried this : {$IFDEF MSWINDOWS} SendMessage(TWinWindowHandle(Memo1).Wnd, EM_SETTABSTOPS, 1, Longint(@lTabWidth)); {$ENDIF} Off course only on Windows but it's doesn't work ! I find nothing in Memo1.model. So does it exists a way to do it on all platforms (IOS, Android, MAcos etc..) ? Share this post Link to post
