hi,

I need to disable the maximize button in a windows application.

is this possible with some easy property setting?

or do i need to traverse active window and try to disable it myself?

thanx Bas

ok i found a solution,

i created a class in c++ with a single function to correct the main window by getting the main window and correct the window and restrict resize.

the function is called from qml, because i do not know when the window is active.

in main.qml it is active.

    void correctWindowSize() {

        QWindow *mw = getMainWindow();
        if( mw == nullptr ) {
            qDebug() << "WINDOW NOT FOUND";
        }
        else {
            Qt::WindowFlags flags = 0;
            flags |= Qt::Dialog;
//            flags |= Qt::Tool;
//            flags |= Qt::WindowTitleHint;

            mw->setFlags(flags);
            mw->setMinimumWidth(mw->width());
            mw->setMinimumHeight(mw->height());
            mw->setMaximumWidth(mw->width());
            mw->setMaximumHeight(mw->height());
        }
    }

    QWindow* getMainWindow()
    {
        foreach (QWindow *w, qApp->allWindows()) {
            if(w->inherits("QWindow")) {
                qDebug() << "window found";
                return w;
            }
        }
        return nullptr;
    }

Hi Bas,

as the QML App and GameWindow types are based on ApplicationWindow, you can set flags or minimum sizes also from QML:

 

import Felgo 3.0
import QtQuick 2.9

App {

  flags: Qt.Dialog

  // ...
}

Best,
Günther

ok thanx, but how do i restrict the resizing?

[Bas]

sorry i need to read the docs 🙂

[Bas]

ah yes, i saw that the editor was saying invalid property name… that is how i ended up with a weird workaround

[GüntherFelgo Team]

Yes, Qt Creator does not offer properties of the derived type ApplicationWindow in auto-completion at the moment, which is a bit confusing.

[Bas]

hmm

the minimum width/height is not working

 

    contentItem.maximumWidth : 640
    contentItem.maximumHeight : 960
    contentItem.minimumWidth : 640
    contentItem.minimumHeight : 960

 

[GüntherFelgo Team]

You can set the properties directly for the window instead of contentItem:

import Felgo 3.0
import QtQuick 2.9

App {

  flags: Qt.Dialog

  maximumWidth : 640
  maximumHeight : 960
  minimumWidth : 640
  minimumHeight : 960
}
