Application in Full-Screen mode

Hi there, I have searched and searched on this site
how to make a application full-screen, but i didn't
found a good solution!

So I have made a beginning:

procedure TMainForm.ToolButton7Click(Sender: TObject);
begin
 with MainForm do
   WindowState := wsMaximized;
   FormStyle := fsStayOnTop;
   Left := 0;
   Top := 0;
   Height := Screen.Height;
   Width := Screen.Width;
   BorderStyle := bsNone;
   StatusBar1.Visible := false
end;
(*-----------------------------------------------*)
procedure TMainForm.ToolButton8Click(Sender: TObject);
begin
   with MainForm do
   FormStyle := fsNormal;
   BorderStyle := bsSizeable;
   StatusBar1.Visible := true
end;
(*-----------------------------------------------*)

I have several question about the procedures above:
1. How can I hide/show the statusbar?
2. When I press the ToolButton8 to get the screen in normal-state
    The rezise-button in the right-top corner doesn't work!

Who can help me out?

Greetings,

Peter

You need to remember the coordinates yourself to switch back. You will need something like this:

FSavedCoords : array[0..3] of Integer;

And then this should do it:

procedure TMainForm.ToolButton7Click(Sender: TObject);
begin
 with MainForm do
   FormStyle := fsStayOnTop;
   FSavedCoords[0] := Left;
   FSavedCoords[1] := Top;
   FSavedCoords[2] := Height;
   FSavedCoords[3] := Width;
   SetBounds(0, 0, Screen.Width, Screen.Height);
   BorderStyle := bsNone;
   StatusBar1.Visible := false;
end;

procedure TMainForm.ToolButton8Click(Sender: TObject);
begin
  with Form1 do
    FormStyle := fsNormal;
    SetBounds(FSavedCoords[0], FSavedCoords[1], FSavedCoords[2], FSavedCoords[3]);
    BorderStyle := bsSizeable;
    StatusBar1.Visible := true;
end;

Also the StatusBar should now react correctly on the .Visible property.

Regards !

Well, I have swapped the Height and Width values from FSavedCoords in ToolButton8Click(), but am sure you get the point. :)

I am sorry, I don't get the point, what do I do wrong?

procedure TMainForm.ToolButton7Click(Sender: TObject);
begin
 with MainForm do
   WindowState := wsMaximized;
   FormStyle := fsStayOnTop;
   FSavedCoords[0] := Left;
   FSavedCoords[1] := Top;
   FSavedCoords[2] := Height;
   FSavedCoords[3] := Width;
   SetBounds(0, 0, Screen.Width, Screen.Height );
   Left := 0;
   Top := 0;
   Height := Screen.Height;
   Width := Screen.Width;
   BorderStyle := bsNone;
   StatusBar1.Visible := false

end;
(*-----------------------------------------------*)
procedure TMainForm.ToolButton8Click(Sender: TObject);
begin
   with MainForm do
   FormStyle := fsNormal;
   SetBounds(FSavedCoords[0], FSavedCoords[1], FSavedCoords[2], FSavedCoords[3]);
   BorderStyle := bsSizeable;
   StatusBar1.Visible := true
(*-----------------------------------------------*)

Replace your function exactly with these, I mark the differences:

procedure TMainForm.ToolButton7Click(Sender: TObject);
begin
 with MainForm do
   // You don't need to change the WindowState
   // WindowState := wsMaximized;
   FormStyle := fsStayOnTop;
   FSavedCoords[0] := Left;
   FSavedCoords[1] := Top;
   FSavedCoords[2] := Width; // changed, now Width instead of Height
   FSavedCoords[3] := Height; // changed, now Height instead of Width
   SetBounds(0, 0, Screen.Width, Screen.Height);
   // SetBounds() will do the same as the four lines below
   // Left := 0;
   //Top := 0;
   // Height := Screen.Height;
   // Width := Screen.Width;
   BorderStyle := bsNone;
   StatusBar1.Visible := false;
end;

That should work...does it?
procedure TMainForm.ToolButton8Click(Sender: TObject);
begin
  with MainForm do
    FormStyle := fsNormal;
    SetBounds(FSavedCoords[0], FSavedCoords[1], FSavedCoords[2], FSavedCoords[3]);
    BorderStyle := bsSizeable;
    StatusBar1.Visible := true;
end;

Your solution did help other problems I had, but the MainMenu-bar
still there.

MainMenuBar? You did not mention that before. What does it and where is the problem?

The procedure works fine to make my application full-screen
except for the MainMenubar, I want to hide the mainmenubar also.
But I don't know how.

To remove:

MainForm.Menu:=nil;

To restore

MainForm.Menu:={name of MainMenu component}

procedure TMainForm.HideTitle;
var actStyle : Integer;
begin
  actStyle := GetWindowLong(Handle, GWL_STYLE);
  SetWindowLong(Handle, GWL_STYLE, (actStyle and (not WS_CAPTION)));
  SetWindowPos(Handle, 0, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE or SWP_NOZORDER or SWP_FRAMECHANGED);  
end;

You will now have the problem that you can not move the window anymore. This will allow moving by clicking anywhere on the window:

Put the following function in the private section of TMainForm:

procedure WMNCHitTest(var msg: TWMNCHitTest); message WM_NCHitTest;

And this is the implementation:

procedure TMainForm.WMNCHitTest (var msg: TWMNCHitTest);
begin
  inherited;
  if ( msg.Result = htClient ) then
    msg.Result := htCaption;
end;
