QLabel embedding in QStatusBar using Qt Designer

Question

Is there any solution to embed a QLabel in QStatusBar using Qt Designer?

Solution 1

I don't believe so. It's fairly simple to add one programmatically, though.

If you're just wanting to show a message, you could use: statusBar()->showMessage(tr("Message Here"));, or alternatively if you really needed a QLabel on the status bar, you could do something along the lines of:

QLabel *label = new QLabel("Message");
statusBar()->addWidget(label);

label would become a child of statusBar(), and appear in the first empty spot from the bottom left (addPermanentWidget(label) would add it to the first empty spot from the bottom right). If you place QLabel label in the classes header (or other var name), you'd be able to access the variable directly later (removing the initial QLabel type from the first line, of course).

Solution 2

It is not possible with Qt Designer. I resolve it by creating label a in Qt Designer and later in constructor of my MainWindows add this line:

Ui::"class name of my MainWindows"::"name of statusBar Object"->addWidget("Object Name of Label");

In my application, the class name of mainwindows is MainWindowsForm, the status bar is named statusBar and the label is named informationLabel. Then I have:

Ui::MainWindowsForm::statusBar->addWidget(informationLabel);

Solution 3

It's not possible even if you would manually edit UI file.

I think it's a defect in QtDesigner

Not a defect but a missing feature. Sadly QtDesigner is not meant for UIs, which have multi-level structure (this includes adding a QLabel to a QStatusbar etc.).

How to adapt the code to use a translatable Message?

@Sigur Any reason you're feeling like this would be significantly different from dealing with any other QLabel?

[Sigur]

Sorry. I was trying to use tr with QLabel but no success. I don't know how to use QLabel with translable text.
