[veera]

Hi ,
No ....need to call in the run time There is Qmainwindow ui in that i have implemented there is a open pushbutton using style sheet ,if i press its has to open qtabwidget after words .....i will show my tableview in that ,its already connected with database server ..........this is my implementation idea....

@veera

ok if you new a tabwidget with no parent, it should become window
then you just a page to it and it should be it

[veera]

how to add and open the page after click the button?

[veera]

if you don't mind please elaborate the concepts.....

@veera

I think i dont understand what you are asking.

void MainWindow::on_pushButton_2_released()
{
  QTabWidget* tw = new QTabWidget(nullptr);
  tw->addTab(new QPushButton("test"),"MYTAB");
  tw->show();
}

Will show a tabwidget as window with one Qpushbutton as tab

Note. just sample. it will make new each time pushed and not delete it.
A dialog would work better.

sorry the main thing is that it has to open as a tab attached to main window ......

[veera]

/QTabWidget *tabWidget = new QTabWidget;

/*QWidget *tab1 = new QWidget;
QWidget *tab2 = new QWidget;
QWidget *tab3 = new QWidget;
setCentralWidget(tabWidget);
tabWidget->insertTab(0,tab1,"Table_1 Data");
tabWidget->insertTab(1,tab2,"Table2 data");
tabWidget->insertTab(2,tab2,"Table3 data");

// tabWidget->tabRemoved(0);
// ui->tabWidget->removeTab(0);
tabWidget->removeTab(2);
Here i manually creating the widgets there are attaching with QMainwindow ....I dont want to create manually need to dynamically open it need to attached to Qmainwindow.......

@veera said in How to add a widget to QMainwindow in qt creator:

I dont want to create manually need to dynamically open it

But using addTab or insertTab IS dynamically ???????
as versus just adding them in Designer.

[veera]

okay fine how about the display of the tabs need join to main window how we can achieve it ?

[mrjj]

@veera

• display of the tabs need join to main window

the tabs are widgets. you can add any the widgets to main window if you use a layout or another tabwidget.

if you need them as tab still, then another tabwidget is needed.

else im not sure what you mean by "join"

[veera]

okay thanks for the support i will try now ...

@veera

Hopefully it answered what you asked.
I not sure what your real issue was, what you have tried and what didnt work :)

[veera]

Hi In the screen below image I have mentioned like this type in one mainwindow button need to implement i could not understand how to start ........please help me

[jsulm]

@veera Sorry, it is really hard to understand you. Isn't this just a QTabWidget containing another QTabWidgets in its tabs?

[veera]

No it should have some control if you click it it has to open it as a tab need to open as you can see in the image i have uploaded?

[jsulm]

@veera You can either use real buttons or qtabwidget containing other qtabwidget and react on tab switch using
http://doc.qt.io/qt-5/qtabwidget.html#currentChanged
But I don't really understand what you're asking for...

[veera]

I have shown in the image .....i dont need full implementation i just need a sample of the image with only one control needed thats it.

[veera]

single menus control with whenever if you click means it has to open a page or tab with (close X) on it ......thats it.

[jsulm]

@veera What is exactly the problem? You can just connect a slot to clicked() signal of a push button (if you use a push button) and show what ever you need in that slot.

[veera]

please find my screen shots these dialog boxes are opening separately ...i don't want to open it separately need to join them to main window as well as it will not allow to do anything after closing window only we can open another window.....
