Custom editors - WPDefEditor, MDIChild problem

quicoli

In my application i added a copy of WPDefActions and WPDefEditor.pas, so, from my aplication i call my custom Editor doing this:

procedure CreateEditor;
var
lForm : TWPToolsEditor;
begin
lForm := TWPToolsEditor.Create(nil);
lForm.ShowModal;
FreeAndNil(lForm);
end;

That´s ok. But my main form is a mdi parent. So i tried do change WPDefEditor.FormStyle to fsMDIChild.
When i create WPDefEditor form, it gets on an infinite loop! Always redrawing screen as crazy. But getting back to fsNormal FormStyle, everything works.

How can make a custom editor be showed as MdiChild ?

Hi,

How can make a custom editor be showed as MdiChild ?

try this:

Code

// This event for auto free !
procedure TWPMdiDemo.WPDefEditorFormClose(Sender: TObject; var Action: TCloseAction);
begin
   Action := caFree;
end;


// Create a new wptools default editor as MDI child
procedure TWPMdiDemo.Button1Click(Sender: TObject);
var
  lForm : TWPToolsEditor;
begin
  WPIsMDIApp := true; // Make the Toolbar MDI compatible
  lForm := TWPToolsEditor.Create(Self);
  lForm.FormStyle := fsMDIChild;
  lForm.OnClose := WPDefEditorFormClose;
end;

WPIsMDIApp is required to avoid the flickering. It changes the behavior of the auto sizing of the TWPToolBar.

Hi Julian,

YES! this woked, but when Editor get closed, an exception is raised. So just to make you know, to avoid that exception, custom editor must be create with NIL, like this:

WPIsMDIApp := true; // Make the Toolbar MDI compatible
lForm := TWPToolsEditor.Create(nil);
lForm.FormStyle := fsMDIChild;
lForm.OnClose := WPDefEditorFormClose;
