How to hide the status bar Qt

Question

I'm trying to create an opening screen for my software. Because I have a status bar in the QMainwindow then Qt makes me a transparent line line at the bottom of the opening screen.

I tried using:

this-> statusBar () -> hide ();
ui-> statusBar-> hide ();

But for some reason Qt ignores them and still show me the transparent line at the bottom of the screen.

I can not remove the status line completely because I used it on the next screen later.

How can I just hide it?

Answer 1

QMainWindow::setStatusBar(nullptr);

You can also use 'this' instead of 'ui'

this->statusbar()->hide();

Alternative: this->statusbar()->setVisible(false);

Ui is the form itself, 'this' is the MainWindow widget. Statusbar() is a member of MainWindow, not the Ui form. You cannot access ui->MainWindow directly, In class MainWindow, access its members with 'this->'.

Answer 2

I tried to use statusbar()->hide() from code, and that didn't solve my specific problem which was that the real estate for the statusbar still existed on the dialog, and also in the UI Designer.

My solution: Manually edit the myview.ui file and remove the line:

<widget class="QStatusBar" name="statusbar"/>

That solved it: no more status bar. (since I didn't want it there, this worked for me)

Answer 3

You can remove both the status bar and menu bar without editing the .ui file.

In Qt Designer or Creator, in the widget tree, find the status bar, right-click it and select "Remove" in the context menu.

The same can be done with the menu bar.
