[mouni]

Hi,


I am trying to move frameless widget according to screen geometry .... i want xpos constant 175 and y pos should move can anybody give some code....

Do you mean you just want to spawn buttons/labels/... on the screen at will? Because then you are in luck I wasted a complete day figuring that out


frmMain is my QMainWindow. btnExtraButton is a button i can press to add a extra button on frmMain. btnRemveAll removes them all.
oListButton is defined by (in frmMain.h) :

using namespace std;
...
	vector<QPushButton*> oListButton;
...
private slots:
	void oTest();

using namespace std;
...
	vector<QPushButton*> oListButton;
...
private slots:
	void oTest();

To copy to clipboard, switch view to plain text mode 

void frmMain::on_btnExtraButton_clicked()
{
	QPushButton *buttonA = new QPushButton(this); //create new button, with this as parent
 
	oListButton.insert(oListButton.end(), buttonA); // use a normal std::vector to store the button, so I can later check which button was pressed
 
        int iXlocation = 50;
        int iYlocation = 50;
        int iHeight = 100;
        int iWidth = 100;
	buttonA->setGeometry(iXlocation , iYlocation , iHeight , iWidth ); // coordinate (0,0) is in the left upper corner. Maybe i switched height en width, you'll find out soon enough
 
	buttonA->show(); // so you can actually see it
 
	QObject::connect(oListButton[oListButton.size() - 1], SIGNAL(clicked()), this, SLOT(oTest()));  //add the last button in the vector to a connect (just so something happened when it got pressed)
}
 
void frmMain::on_btnRemoveAll_clicked()
{
	for (int a = 0; oListButton.size() > a; a++)
	{
		QObject::disconnect(oListButton[a], SIGNAL(clicked()), this, SLOT(oTest()));
		oListButton[a]->hide();
		oListButton[a]->deleteLater();
	}
	oListButton.clear();
}
 
void frmMain::oTest()
{
	QObject* obj = sender(); //obj is now the object of the sender, which i will find in my vector with a for-loop
	int iTest = -1;
	for (int a = 0; oListButton.size() > a; a++)
	{
		if (oListButton[a] == sender())
		{
			iTest = a;
		}
	}
 
}

void frmMain::on_btnExtraButton_clicked()
{
	QPushButton *buttonA = new QPushButton(this); //create new button, with this as parent

	oListButton.insert(oListButton.end(), buttonA); // use a normal std::vector to store the button, so I can later check which button was pressed
      
        int iXlocation = 50;
        int iYlocation = 50;
        int iHeight = 100;
        int iWidth = 100;
	buttonA->setGeometry(iXlocation , iYlocation , iHeight , iWidth ); // coordinate (0,0) is in the left upper corner. Maybe i switched height en width, you'll find out soon enough

	buttonA->show(); // so you can actually see it

	QObject::connect(oListButton[oListButton.size() - 1], SIGNAL(clicked()), this, SLOT(oTest()));  //add the last button in the vector to a connect (just so something happened when it got pressed)
}

void frmMain::on_btnRemoveAll_clicked()
{
	for (int a = 0; oListButton.size() > a; a++)
	{
		QObject::disconnect(oListButton[a], SIGNAL(clicked()), this, SLOT(oTest()));
		oListButton[a]->hide();
		oListButton[a]->deleteLater();
	}
	oListButton.clear();
}

void frmMain::oTest()
{
	QObject* obj = sender(); //obj is now the object of the sender, which i will find in my vector with a for-loop
	int iTest = -1;
	for (int a = 0; oListButton.size() > a; a++)
	{
		if (oListButton[a] == sender())
		{
			iTest = a;
		}
	}

In your "clear all" slot you can just use qDeleteAll, to delete all buttons

qDeleteAll(oListButton);
oListButton.clear();

qDeleteAll(oListButton);
oListButton.clear();

To copy to clipboard, switch view to plain text mode 

In the oTest slot you can also cast the sender instead of looping through the container if you need the object by its actual type

QPushButton *button = qobject_cast<QPushButton*>(sender());

QPushButton *button = qobject_cast<QPushButton*>(sender());

To copy to clipboard, switch view to plain text mode 

If you just need the index, then I would suggest using a QVector instead of std::vector and using QVector::indexOf().
