How to make KDDockWidgetsMainWindow work within another provided main window?

How to make KDDockWidgetsMainWindow work within another provided main window?
I have another MainWindow provided by a component vendor, so I must use that.
I set the parent of KDDockWidgets::MainWindow to the other main window.
I then add this to a layout which is part of the CentralWidget.
I get what looks like a functional DockWidget -- but it is half broken. I cannot dock the widgets to each other or within the window. The docking indicator displays do not appear at all... The image shows the two widgets created successfully at the bottom of the screen (data1, data2), but moving the widgets around does not transmit events to the underlying main (I presume) - so the widgets are unaware of how to dock. How do I use KDDockWidget when a MainWindow is already provided? This is probably a common usage case. Picture & code follows as:

KDDockWidgets::MainWindow * dmw = new KDDockWidgets::MainWindow(QStringLiteral("KDDocker"), KDDockWidgets::MainWindowOption_None, this);
dmw->setFixedHeight(120);
{
auto dock = new KDDockWidgets::DockWidget(QStringLiteral("data1"));
auto* label = new QLabel(dock);
label->setText("1.1111");
label->setFont(QFont("Arial", 16));
dock->setWidget(label);
dock->show();
dmw->addDockWidget(dock, KDDockWidgets::Location_OnLeft);
}
{
auto dock = new KDDockWidgets::DockWidget(QStringLiteral("data2"));
auto* label = new QLabel(dock);
label->setText("22222.22");
label->setFont(QFont("Arial", 16));
dock->setWidget(label);
dock->show();
dmw->addDockWidget(dock, KDDockWidgets::Location_OnRight);
}
_WidgetSwitcher->_CentralWidgetVBoxLayout->addWidget(dmw);
dmw->show();
setCentralWidget(_WidgetSwitcher);

Thanks for any responses,

Perhaps this is the same bug as issue #168.

Can you modify examples/minimal/ then attach a .diff file here (or a link to your github with the change commited) ?

Then I can debug it quickly

Attached is a minimal file which creates a class derived from QMainWindow. Code is also copied/pasted.

That class holds another widget which contains a VBoxLayout which contains a KDDockWidgets::MainWindow with a number of DockWidgets. It renders the dockwidgets properly, but docking does not occur within the window. If I remove dockwidgets from the window, docking can occur in a floating window, but I cannot get the floating window back into the VBox

Hi Sergio, See attached minimal example.

I am still showing the same behaviour with the code I sent... Using Microsoft Windows, VS 2019 #include <QApplication> #include <QMainWindow> #include <QVBoxLayout> #include <QLabel> #include <kddockwidgets/DockWidget.h> #include <kddockwidgets/MainWindow.h> class Widget : public QWidget { public: Widget(QWidget* parent = nullptr, Qt::WindowFlags flags = 0) : QWidget(parent, flags) { KDDockWidgets::MainWindow* dockMainWindow = new KDDockWidgets::MainWindow(QStringLiteral("KDDocker"), KDDockWidgets::MainWindowOption_None); dockMainWindow->setFixedHeight(500); for(int i = 1; i <= 5; ++i) { QString name = ("window_" + std::to_string(i)).c_str(); auto dock = new KDDockWidgets::DockWidget(name); auto* label = new QLabel(dock); label->setText(name); dock->setWidget(label); dockMainWindow->addDockWidget(dock, KDDockWidgets::Location_OnLeft); } QVBoxLayout* vBoxLayout = new QVBoxLayout(this); vBoxLayout->addWidget(dockMainWindow); } }; class MainWindowTest : public QMainWindow { public: MainWindowTest(QWidget* parent = nullptr, Qt::WindowFlags flags = 0) : QMainWindow(parent, flags) { Widget* widget = new Widget(this); setCentralWidget(widget); show(); } }; int main(int argc, char* argv[]) { QApplication qApplication(argc, argv); MainWindowTest mainWindowTest; qApplication.exec(); return 0; }
