Problems with QActiongroup, QMenu, Qsettings

Hi everyone,

I have QMenu - LegendPositionSubMenu where I can choose the position of the legend on my plot, there are 4 QActions inside QActiongroup: right, left,top,bottom.
I want to save the position in Qsettings, for this I wrote writeSettings():

Code:

---

void CLegendMenu::writeSettings()
{
	QSettings settings;
	settings.beginGroup("legendSettings");
	//add the value of CurrentPosition
	settings.setValue("position", CurrentPosition);
	settings.endGroup();
}

---

Current position is of the enum type Position.
and I read it:

Code:

---

void CLegendMenu::readSettings()
{
	//read the currentPosition
	QSettings settings;
	settings.beginGroup("legendSettings");
 
  if (settings.value("position")== 0)
	{
 
	}
	else if (settings.value("position")== 1)
	{
	}
	settings.endGroup();
}
etc....

I am stucked here, because I want check action inside the menu according to the CurrentPosition value, so it can emit signal trigged(action) and for this I have already working connection.

Thank you
I don't know how to perform it

If you want to display the CurrentPosition in the QAction/QMenu, then you need to build the QAction/QMenu dynamically as and when the user selects the QMenu

I want to save CurrentPosition when I close my application and then restore when I open it again using Qsettings. QMenu is building up every time I open the application.

See if ths example helps

Code:

---

#include <QMenu>
#include <QAction>
#include <QSettings>
#include <QApplication>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QMenu menu("Position Menu");
    QSettings* settings = new QSettings("settings.ini", QSettings::IniFormat, &a);
 
    settings->beginGroup("Position");
    bool up = settings->value("up", false).toBool();
    bool right = settings->value("right", false).toBool();
    bool down = settings->value("down", false).toBool();
    bool left = settings->value("left", false).toBool();
    settings->endGroup();
 
    QAction* up_action = menu.addAction("up");
    up_action->setCheckable(true);
    up_action->setChecked(up);
 
    QAction* right_action = menu.addAction("right");
    right_action->setCheckable(true);
    right_action->setChecked(right);
 
    QAction* down_action = menu.addAction("down");
    down_action->setCheckable(true);
    down_action->setChecked(down);
 
    QAction* left_action = menu.addAction("left");
    left_action->setCheckable(true);
    left_action->setChecked(left);
 
    menu.show();
 
    a.connect(&menu, SIGNAL(aboutToHide()), SLOT(quit()));
 
    int ret = a.exec();
 
    up = up_action->isChecked();
    right = right_action->isChecked();
    down = down_action->isChecked();
    left = left_action->isChecked();
 
    settings->beginGroup("Position");
    settings->setValue("up", up);
    settings->setValue("right", right);
    settings->setValue("down", down);
    settings->setValue("left", left);
    settings->endGroup();
 
    return ret;
}
