How to save non-MainWindow size/position [Solved]

[kloveridge]

I am writing a desktop application that has a main window and two pop up windows (lets call those the Log and Browser).

I figured out how to save size/position of the main window using this code:

void MainWindow::writePositionSettings()
{
	QSettings qsettings("esp", "lotus");
	qsettings.beginGroup("mainwindow");
	qsettings.setValue("geometry", saveGeometry());
	qsettings.setValue("savestate", saveState());
	qsettings.setValue( "maximized", isMaximized() );
	if ( !isMaximized() ) {
		qsettings.setValue( "pos", pos() );
		qsettings.setValue( "size", size() );
	}
	qsettings.endGroup();
	qDebug() << "Saving main window size and position.";
}

void MainWindow::readPositionSettings()
{
	QSettings qsettings( "esp", "lotus" );

	qsettings.beginGroup( "mainwindow" );
	restoreGeometry(qsettings.value( "geometry", saveGeometry() ).toByteArray());
	restoreState(qsettings.value( "savestate", saveState() ).toByteArray());
	move(qsettings.value( "pos", pos() ).toPoint());
	resize(qsettings.value( "size", size() ).toSize());
	if ( qsettings.value( "maximized", isMaximized() ).toBool() )
		showMaximized();
	qsettings.endGroup();
}

This works with my main window. My original assumption was I could "daisy chain" the storage pattern by putting similar code in my Browser and Log window. but Qt complained it didn't recognize the commands. I wondered if QSettings was just for a main window and not auxiliary windows. Just hoping for Qt Guru to give me some pointers.

Sure you can use QSettings to save any Windows, Dialog geometry,

Just make sure you load the settings and use a different "group" so your settings do not clash togethers.

Here is a working example of one of my QDialog:

 void WorkoutDialog::loadInterface() {

QSettings settings("MaxPowerVelo", "PowerVelo");

settings.beginGroup("WorkoutDialog");


resize(settings.value("size", QSize(1024, 768)).toSize());
move(settings.value("pos", QPoint(200, 200)).toPoint());

QList<int> mySize;
mySize.append( settings.value("splitter0", 2).toInt() );
mySize.append( settings.value("splitter1", 35).toInt() );
mySize.append( settings.value("splitter2", 37).toInt() );
mySize.append( settings.value("splitter3", 27).toInt() );
ui->splitter->setSizes(mySize);



bool wasFullscreen = settings.value("fullscreen", false).toBool();
settings.endGroup();

if (wasFullscreen) {
    wasFullscreenOnOpen = true;
    showFullScreenWin();
}
else {
    wasFullscreenOnOpen = false;
    this->setSizeGripEnabled(true);
    ui->widget_topMenu->setMinExpandExitVisible(false);
    ui->widget_topMenu->updateExpandIcon();
}

}

void WorkoutDialog::saveInterface() {



//// ------------ Save interface
QSettings settings("MaxPowerVelo", "PowerVelo");

settings.beginGroup("WorkoutDialog");
settings.setValue("size", size());
settings.setValue("pos", pos());


QList<int> sizeNow = ui->splitter->sizes();
settings.setValue("splitter0", sizeNow.at(0));
settings.setValue("splitter1", sizeNow.at(1));
settings.setValue("splitter2", sizeNow.at(2));
settings.setValue("splitter3", sizeNow.at(3));


if (this->isFullScreen()) {
    settings.setValue("fullscreen", true);
}
else {
    settings.setValue("fullscreen", false);
}

settings.endGroup();
}

I only had a few minutes this morning to really try this. I will give it another shot tonight.

You actually answered one of my other questions about how to save sub-components (like a splitter) in your pasted code. So you can stick a "I am awesome" gold star to your forehead for the day. ;)

Hehe glad I could help!

"I am awesome" Max (for the day) :)
