drag zone on window without title

[Otto]

In this application I can drag the window from everywhere on the red zone.
Does someone know how to do this?
Thanks in advance
Otto

Otto,

You have to use bLClicked to set a lDrag variable to .T., then use bMMoved to move the window and finally bLButtonUp to set the lDrag to .F.

oWnd:bLClicked = { || lDrag := .T. }
oWnd:bMMoved = { |nRow, nCol | If( lDrag, oWnd:Move( nRow, nCol ),) }
oWnd:bLButtonUp = { || lDrag := .F. }

Otto,

Here you have a working sample:

Code: Select all  Expand view  RUN

#include "FiveWin.ch"

function Main()

   local oWnd, nRowPos, nColPos, lDrag := .F.

   DEFINE WINDOW oWnd STYLE WS_POPUP COLOR "W/R"

   oWnd:bLClicked := { | nRow, nCol | nRowPos := nRow, nColPos := nCol, lDrag := .T. }
      
   oWnd:bMMoved = { | nRow, nCol | If( lDrag, oWnd:Move( oWnd:nTop + nRow - nRowPos,;
                                         oWnd:nLeft + nCol - nColPos ),) }   
   oWnd:bLButtonUp := { || lDrag := .F. }

   ACTIVATE WINDOW oWnd
     
return nil

Hello Antonio,
thank you for your help.
Could you please have another look.

I would need this for MDI windows.
The ECR prints to the screen and there can be many receipts at one time.
The cook can with a touch screen sort the receipts and click crossed out the meals he so far has prepared.
A timer watch the directory and brings up the receipt to the screen. First all the meal are announced with Playsound() – thanks to you it is working .

It would be nice if the zone to drag the receipts would be bigger than the title because you have to use your fingers.

#include "FiveWin.ch"
#include "InKey.ch"
#include "xbrowse.ch"

Please post a screenshot, thanks

BTW, your proposed example fails to properly run. Please check it before posting it

[Otto]

Antonio, which one do you mean?

Antonio, thank you very much.

Now I start the finishing.

Otto

PS: I helped Ruth to set up a portal for our codesnips project. Ruth placed the FW logo on it.
Is it OK for you?
