Window flags not helping in mdiarea in Qt

I am using Qt and creating a GUI with multiple sub windows. I am using MDI Area for the same. I want to hide the top toolbar of mdi subwindow but using window flags is not helping.

I have tried writing the code as follows. First I tried for mdiarea and then for subwindow but neither worked.

mdiarea.setWindowsFlags(Qt::FramelessWindowHint);

subwindow.setWindowsFlags(Qt::FramelessWindowHint);

I have also tried using Qt::CustomizedWindowHint but even that is not helping. Please help me with this.

Thank You.

Try this:

mdiArea->addSubWindow(new QLabel("Qt::FramelessWindowHint"), Qt::FramelessWindowHint);

You don't want to set the MDI area itself as a frameless window, because it's a widget you likely have embedded in another window... it most likely already doesn't have a frame.

Your setting the 'subwindow' should work... but addSubWindow(myWidget) actually wraps the widget passed in in the real subwindow, so that's what was going wrong. Qt lets you pass in window flags as the second parameter of addSubWindow() and those flags go to the real subwindow.

Note that with a frameless window, you can't drag the window around to move it, or grab the edges to resize it, because there's nothing for you to grab onto!

If you just want the minimize and maximize buttons gone (but still want the close button), try passing Qt::Dialog instead.

Try also experimenting with these:

addSubWindow(new QLabel("Qt::Tool"), Qt::Tool);
addSubWindow(new QLabel("Qt::Tool|Qt::CustomizeWindowHint"), Qt::Tool|Qt::CustomizeWindowHint);
addSubWindow(new QLabel("Qt::Dialog"), Qt::Dialog);

I think Qt::Tool|Qt::CustomizeWindowHint is probably the best option (no buttons, but still movable and resizable - if you don't want it resizable, give it a fixed size (setFixedSize()).

Edit: Also try: Qt::CustomizeWindowHint|Qt::WindowTitleHint
