[finyone]

hello everyone, i use the QDockWidget widget, but i do not want user to close the QDockWidget, so ,i want to hidden the close button, i have tried :
scenesDock->setFeatures(QDockWidget::NoDockWidgetFeatures);
but it doesn't work.
so i tried:
scenesDock->setFeatures(QDockWidget::DockWidgetFloatable|QDockWidget::DockWidgetMovable);
but it also doesn't work. the close button is also there.
how can i do that?

@finyone Isn't QDockWidget::DockWidgetClosable what you need?

Removing QDockWidget::DockWidgetClosable I would say:

scenesDock->setFeatures(scenesDock->features() & ~QDockWidget::DockWidgetClosable);

Hi
What platform are you on?
It does work on windows.

@mrjj thanks for your reply, i use OBS studio, that is a soft for live video.

and i use it in windows, the code is
"
ui->setupUi(this);
ui->previewDisabledLabel->setVisible(false);
ui->scenesDock->setFeatures(ui->scenesDock->features() & ~QDockWidget::DockWidgetClosable);
"

but run it , i find the close button is also there , Does it need me also set the QDockWidget's setFeatures in GUI designer ?

Hi that is od as seems fine.
Well anything you setup in Designer is done after
ui->setupUi(this);

So i wonder if its due to it already being docked.

Could you try sample ?

and at line 450 in mainwindow.cpp, function void MainWindow::createDockWidget()

void MainWindow::createDockWidget()
{
    CreateDockWidgetDialog dialog(this);
    if (dialog.exec() == QDialog::Rejected)
        return;

    QDockWidget *dw = new QDockWidget;
    dw->setFeatures(dw->features() & ~QDockWidget::DockWidgetClosable); <<<<<
...

and run then insert one from menu.

and see if it still has close button.

scenesDock->setFeatures(QDockWidget::NoDockWidgetFeatures); did the job for me if you still have the problem i believe this will solve the issue
