Hi and welcome to the forums

Did you try to create a frameless for each ?

// 1
FramelessWindow * framelessWindow = new FramelessWindow;
MainWindow *mainWindow = new MainWindow;
framelessWindow->setContent(mainWindow);
// 2
FramelessWindow * framelessWindow2 = new FramelessWindow;
MainWindow *mainWindow2 = new MainWindow;
framelessWindow2->setContent(mainWindow2);

framelessWindow2->setContent(mainWindow2);

thanks for fast reply
this code doesn't work
this time no ui come up at all

my code first of all open a window
when i click a button in first windows, second window open (first window hide)

a.setStyle(new DarkStyle);

  // create frameless window (and set windowState or title)
  FramelessWindow framelessWindow;
  //framelessWindow.setWindowState(Qt::WindowMaximized);
  framelessWindow.setWindowTitle("SubRan Patcher");
  framelessWindow.setWindowIcon(QIcon(":/png/sr-removebg-preview.png"));

  // create our mainwindow instance
  MainWindow *mainwindow = new MainWindow;
  MainWindow2 *mainwindow2 = new MainWindow2;

  // add the mainwindow to our custom frameless window
  framelessWindow.setContent(mainwindow);
  framelessWindow.setContent(mainwindow2);
  framelessWindow.show();

  return a.exec();

when i use this code my program start like this

as you can see my two windows showed together in one window

Hi
You still using same frameless for both
framelessWindow.setContent(mainwindow);
framelessWindow.setContent(mainwindow2);

what can i do about this?
i use 2 frameless in my test too but the output is second window doesn't show (only a empty frameless window show)

also i use this code in mainwindow.cpp to show new window and hide old one

void MainWindow::on_pushButton_clicked()
{
    // ----- Hide old Window and show new window ----- //
     hide();
     mainwindow2 = new MainWindow2(this);
}

mrjj

@saeid0034
so you did try with
FramelessWindow framelessWindow;
FramelessWindow framelessWindow2;

and it wont show ?

also the on_pushButton_clicked will just make a new one and NOT USE frameless as you dont add that ot it like you do in main.

what can i do?
you mean i need somthing like this in my mainwindow.cpp?

void MainWindow::on_pushButton_clicked()
{
    // ----- Hide old Window and show new window ----- //
     hide();

     // style our application with custom dark style
     setStyle(new DarkStyle);

     // create frameless window (and set windowState or title)
     FramelessWindow framelessWindow2;
     //framelessWindow.setWindowState(Qt::WindowMaximized);
     framelessWindow2.setWindowTitle(".r");
     framelessWindow2.setWindowIcon(QIcon(":/png/sr-removebg-preview.png"));

     // create our mainwindow instance
     MainWindow2 *mainwindow2 = new MainWindow2;

     // add the mainwindow to our custom frameless window
     framelessWindow2.setContent(mainwindow2);
     framelessWindow2.show();

     //mainwindow2 = new MainWindow2(this);
}

sorry for asking lots of question (and sorry about mistake in framelessWindow2.setWindowTitle in above code)

mrjj

Hi
seems ok.
Yes you need to to the same each time you create a Window you want to be frame less

one thing.

setStyle(new DarkStyle);

that sets on the current MainWindow and i thnik you need that on the new one

// create our mainwindow instance
MainWindow2 *mainwindow2 = new MainWindow2;
mainwindow2 -> setStyle(new DarkStyle);

sorry for asking lots of question
That is quite allright :)

i tested it with following code

         hide();
         // create frameless window (and set windowState or title)
         FramelessWindow framelessWindow2;
         //framelessWindow.setWindowState(Qt::WindowMaximized);
         framelessWindow2.setWindowTitle(".r");
         framelessWindow2.setWindowIcon(QIcon(":/png/sr-removebg-preview.png"));

         // create our mainwindow instance
         MainWindow2 *mainwindow2 = new MainWindow2;
         mainwindow2 -> setStyle(new DarkStyle);

         // add the mainwindow to our custom frameless window
         framelessWindow2.setContent(mainwindow2);
         framelessWindow2.show();

         //mainwindow2 = new MainWindow2(this);

but again it show me only a blank frameless window of my second ui file

one other point is as you can see WindowTitle is test (i use this title in my frist windown in main.cpp) its not use new WindowTitle i set in above code

Hi
Sorry was not paying enough focus.

You cannot do
FramelessWindow framelessWindow2;

as it will run out of scope. That only works in main.cpp

you MUST new them as you do with MainWindow

how can i add new FramelessWindow framelessWindow2 in main.cpp and then use it onvoid MainWindow::on_pushButton_clicked()in mainwindow.cpp?

mrjj

@saeid0034

Hi you dont need to add it there you can add anywhere but you must NEW it then

and not as local variable as then it runs out of scope.

So what i mean is just to do
FramelessWindow * framelessWindow2 = new FramelessWindow ;

and not just
FramelessWindow framelessWindow2; // this is a local variable and as soon as
on_pushButton_clicked ends , it will be deleted

so you have to new it

thanks
i do what you say
this time second window open when i click button
but old blank frameless window still open too

void MainWindow::on_pushButton_clicked()
{
    // ----- Hide old Window and show new window ----- //
     hide();
     FramelessWindow * framelessWindow2 = new FramelessWindow ;
     // style our application with custom dark style
     setStyle(new DarkStyle);
     //framelessWindow.setWindowState(Qt::WindowMaximized);
     framelessWindow2->setWindowTitle("test");
     framelessWindow2->setWindowIcon(QIcon(":/png/sr-removebg-preview.png"));

     // create our mainwindow instance
     MainWindow2 *mainwindow2 = new MainWindow2;

     // add the mainwindow to our custom frameless window
     framelessWindow2->setContent(mainwindow2);
     framelessWindow2->show();
}

The other empty one, is that from you create 2 in main.cpp or
do you only create one there?

i only create one

Ok i think we need to hide the parent too.
instead of
// ----- Hide old Window and show new window ----- //
hide();
try
parentWidget()->hide();
to hide the framelss instead of the MainWIn we put inside.

@mrjj said in How to create VS2013 like frameless window with dark style:

parentWidget()->hide();

still two window
but this time with this look

mrjj

@saeid0034
Hmm so apparently the FrameLess is not the actual parent. must be a holding frame or something.
(i dont have it installed )

try
if (parentWidget()->parentWidget())
parentWidget()->parentWidget()->hide();

and see if thats enough :)
