Coordinates widget

[A Former User]

I have a dockWidget with its original position and then I move it...after that I moved it I want that I press a button and it gets its original position in MainWindow..but I can't, Can you help me?

@vale88 Did you store its original position somewhere?

@jsulm said in Coordinates widget:

Did you store its original position somewhere

yes but if write move(100, 40) I don't obtain its position relative to MainWindow

[jsulm]

@vale88 I guess because it is inside a widget (central widget) not main window. How do you store original coordinates (can you show the code)?

[A Former User]

@jsulm #include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDebug>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
real_pos= ui->dockWidget_2->mapToGlobal(QPoint(100,40));

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::on_pushButton_clicked()
{
ui->dockWidget_2->setFloating(true);
}

void MainWindow::on_pushButton_2_clicked()
{
ui->dockWidget_2->move(real_pos.x(), real_pos.y());

}

@vale88 If I don't mistake, you must not use mapToGlobal because it converts widget coordinates to screen coordinates. If you want to move widget relative to MainWindows you must move to 100,40.

So real_pos = QPoint(100, 40);

@CP71 I tried but the problem remains...I have a problem with dockwidget..they stick to mainwindow..so I must do a function with move

[CP71]

@vale88 Do you have a layout?

[A Former User]

@CP71 I put dockwidget in a layout of a stacked widget

[CP71]

@vale88 I suppose that layout is the problem, layout is placing your widget.
This explains because you can't position your widget as you wish.

@CP71 I want posizionate my dockwidget wherever I want, but I can't because the dockwidget attached to the MainWindow

@vale88 Only thing that comes to mind is to move your widget out of the layout. If it is possible for your UI.
