setGeometry Unable to set geometry

@jsulm , what I meant was displayed in the console.

Hi
It might be the old bug
https://bugreports.qt.io/browse/QTBUG-73258

I have seen it on Linux with 5.9 even its listed as 5.12

you can try set minimumsize on it to
1246x801 if you haven't done already.

• QRect(0,0 732x480)
  when do you print this out ? The window must be visible at that time
  or the numbers might mean nothing.

@mrjj , thank you, I just tried that, still the same:

QWindowsWindow::setGeometry: Unable to set geometry 732x480+-2928+446 on QWidgetWindow/'MainWindowWindow'. Resulting geometry:  738x497+-2928+446 (frame: 8, 31, 8, 8, custom margin: 0, 0, 0, 0, minimum size: 732x480, maximum size: 16777215x16777215).

Hello!

I have the same issue previously. I fixed it by increasing the size of window/dialog. Try to change the width/height of your window.
For example, set 740x480 or 740x500. Please let me know if this works for you. Happy coding!

@Cobra91151 , size isn't a problem :). really it isn't, it does look like a bug as I'm not sure why the message is reporting -2928 for the width?

[Cobra91151]

@SPlatten

I do not think -2928 is the width. It is the rect.x() position. In your case the width is 732, height - 480, x - 2928 and y - 446.

You can check out the source:

void QWindowsWindow::setGeometry(const QRect &rectIn)
{
    QRect rect = rectIn;
    // This means it is a call from QWindow::setFramePosition() and
    // the coordinates include the frame (size is still the contents rectangle).
    if (QWindowsGeometryHint::positionIncludesFrame(window())) {
        const QMargins margins = frameMargins();
        rect.moveTopLeft(rect.topLeft() + QPoint(margins.left(), margins.top()));
    }
    if (m_windowState == Qt::WindowMinimized)
        m_data.geometry = rect; // Otherwise set by handleGeometryChange() triggered by event.
    if (m_data.hwnd) {
        // A ResizeEvent with resulting geometry will be sent. If we cannot
        // achieve that size (for example, window title minimal constraint),
        // notify and warn.
        setGeometry_sys(rect);
        if (m_data.geometry != rect && (isVisible() || QLibraryInfo::isDebugBuild())) {
            qWarning("%s: Unable to set geometry %dx%d+%d+%d on %s/'%s'."
                     " Resulting geometry:  %dx%d+%d+%d "
                     "(frame: %d, %d, %d, %d, custom margin: %d, %d, %d, %d"
                     ", minimum size: %dx%d, maximum size: %dx%d).",
                     __FUNCTION__,
                     rect.width(), rect.height(), rect.x(), rect.y(),
                     window()->metaObject()->className(), qPrintable(window()->objectName()),
                     m_data.geometry.width(), m_data.geometry.height(),
                     m_data.geometry.x(), m_data.geometry.y(),
                     m_data.frame.left(), m_data.frame.top(),
                     m_data.frame.right(), m_data.frame.bottom(),
                     m_data.customMargins.left(), m_data.customMargins.top(),
                     m_data.customMargins.right(), m_data.customMargins.bottom(),
                     window()->minimumWidth(), window()->minimumHeight(),
                     window()->maximumWidth(), window()->maximumHeight());
        }
    } else {
        QPlatformWindow::setGeometry(rect);
    }
}

So, I think the widget geometry is smaller than the layout contents, that is why it reports such issue. You can try to adjustSize method (https://doc.qt.io/archives/qt-5.9/qwidget.html#adjustSize) or you can set it manually.

Code:

mpMainWnd->adjustSize();
mpMainWnd->show();

For example in your case it reports as 738x497 to fix this issue or make it bigger as I suggested in my previous post.

@Cobra91151 , I've now changed the minimum width and height to 1200x800, still getting:

QWindowsWindow::setGeometry: Unable to set geometry 1200x800+-3162+286 on QWidgetWindow/'MainWindowWindow'. Resulting geometry:  1206x817+-3162+286 (frame: 8, 31, 8, 8, custom margin: 0, 0, 0, 0, minimum size: 1200x800, maximum size: 16777215x16777215).

I took a screen shot of the window and pasted into Paint, the size of the final window is 1208x849.

@SPlatten

Ok. It would be better to create some minimal test project to reproduce this issue, so I can find a solution.
The reason could be a missing parent, widgets size/layouts issue etc.

[SPlatten]

@Cobra91151 , thank you, but sorry, that would take more time than I have right now.

@Cobra91151 If the MainWindow is the at the top level of the application, there isn't a parent is there?

[Cobra91151]

@SPlatten said in setGeometry Unable to set geometry:

@Cobra91151 If the MainWindow is the at the top level of the application, there isn't a parent is there?

If you mean something like this:

Code:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Dialog w;
    w.show();
    return a.exec();
}

Then no parent is needed. But, if you have some object class in which you check what dialog to display as the top level, then I would suggest setParent to the app object:

Code:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MyStartup obj;
    obj.setParent(&a);
    return a.exec();
}

But I do not think it will fix your issue. Have you tried for example: setFixedSize method to check if this issue still exists? Also, you can set setWindowFlags method: Qt::MSWindowsFixedSizeDialogHint to make window not resizable on Windows just for a test.

Additionally, you can try to find what causes it using the code below in your main method (main.cpp):

#ifdef QT_DEBUG
    qputenv("QT_FATAL_WARNINGS", "1");
    qputenv("QT_MESSAGE_PATTERN",
            "Type: %{type}\nProduct Name: %{appname}\nFile: %{file}\nLine: %{line}\nMethod: %{function}\nThreadID: %{threadid}\nThreadPtr: %{qthreadptr}\nMessage: %{message}");
 #endif

It will work only in Debug mode and should display more details about your issue. Without any code it is hard to find the root of your issue.
