Search the layout of a widget

[bozo6919]

for remove this widget and apply another widget

[SGaist]

Then you are doing it from the wrong place.

Can you explain what exactly you want to achieve with your application ?

[bozo6919]

I have for beginning à QMainWindow.
I apply to them à QWidget.
At this QWidget, I apply a QVBoxLayout
At this QVBoxLayout, I apply a QWidget named ContentPanel.
What I Want is when my mouse is on a widget named ContentPanel, the layout of this widget remove this widget, I create another QWidget named ContentPanel, and I apply at those ContentPanel a QSplitter.
I have now 2ContentPanel separated by a QSplitter
If I selected the other QWidget named ContentPanel, it has to do the same.

My program has to do this at infinite

(Sorry for my English again ^^')

[SGaist]

You want to add a new widget each time you hover over any of them ?

[bozo6919]

@SGaist Yes, separated by a QSplitter

[SGaist]

Can you explain why ?

[bozo6919]

It's for my job, I'm student

[SGaist]

I meant: why do you want to have new widgets created as soon as you hover over one of them ? Because it means that each time your mouse cursor goes over any of them there's a new one that's going to appear so it can very quickly becomes a mess.

I saw this post : https://forum.qt.io/topic/84616/replacing-a-widget-with-another-one-containing-splitter/3
I want to do like him, look at this picture :

Evert box have to be separated by a splitter. But I don't know how to apply at one box two splitters... :/
I know that I can apply container with QVBoxLayout and QWidget but I don't know how to do what I want with that

[SGaist]

Ok, click is not the same as hover and definitely less dangerous in terms of accidental widget explosion. What will the "clicked widget" contain ?

[bozo6919]

Yes ^^
The "clicked widget" is a class TabbedWindow
But It's the same that QWidget.

[SGaist]

Then you have to either implement an event filter to listen to the mouse press event on all of these widgets, or re-implement the mousePressEvent of your TabbedWindow and emit a signal that specify which region was clicked so you can connect to it and add new widgets appropriately.

[bozo6919]

I have already connect buttons and event but I don't know how create splitters between two tabbed window correctly

[bozo6919]

I have something but with some bugs too :/

I have to save a configuration for example that :

How can I do with QSettings for save all these data ? I have this :

    QSettings settings("settings.ini", QSettings::IniFormat);

    settings.setValue("MainWindow/geometry", window->saveGeometry());
    settings.setValue("MainWindow/state", window->saveState());
    settings.setValue("MainWindow/nbrTabbedWindow", tabbed.size());
    for (int i = 0; i < tabbed.size(); i += 1) {
        QString path = "MainWindow/TabbedWindow/" + QString::number(i);

        settings.beginGroup(path.toStdString().c_str());
        settings.setValue("splitter/geometry", tabbed[i]->splitter->saveGeometry());
        settings.setValue("splitter/state", tabbed[i]->splitter->saveState());
        settings.setValue("containerWidget/geometry", tabbed[i]->containerWidget->saveGeometry());
        settings.setValue("nbrWindows", tabbed[i]->windows.size());
        for (int j = 0; j < tabbed[i]->windows.size(); j += 1) {
            QString pathWindowGeo = "/windows" + QString::number(j) + "/geometry";
            QString pathWindowSta = "/windows" + QString::number(j) + "/state";
            QString pathContentTextGeo = "/contents" + QString::number(j) + "/text/geometry";
            QString pathContentTextTxt = "/contents" + QString::number(j) + "/text/text";
            QString pathContentWidgetGeo = "/contents" + QString::number(j) + "/widget/geometry";
            QString pathContentWidgetSty = "/contents" + QString::number(j) + "/widget/styleSheet";

            settings.setValue(pathWindowGeo.toStdString().c_str(), tabbed[i]->windows[j]->saveGeometry());
            settings.setValue(pathWindowSta.toStdString().c_str(), tabbed[i]->windows[j]->saveState());
            settings.setValue(pathContentTextGeo.toStdString().c_str(), tabbed[i]->contents[j]->text->saveGeometry());
            settings.setValue(pathContentTextTxt.toStdString().c_str(), tabbed[i]->contents[j]->text->text());
            settings.setValue(pathContentWidgetGeo.toStdString().c_str(), tabbed[i]->contents[j]->widget->saveGeometry());
            settings.setValue(pathContentWidgetSty.toStdString().c_str(), tabbed[i]->contents[j]->widget->styleSheet());
        }
        settings.endGroup();
    }

But There are not other ways more simple?
And with my method, I cannot for the moment save splitter's children
