Hi
Even when I read the post a few times, im not really sure what you ask about.

Do you ask how to make tabs dynamic ?
Or just widgets at runtime?

Do you ask how to connect on to MS SQL server
which is running in Ubuntu 16.10 ( i though it only runs on windows)
or what do you ask about ?

for database , you can start here
http://doc.qt.io/qt-5/qtsql-index.html

leave the data base part ....i want implement mainwindow with some ribbon panel controls on it if i am try to click it has to open the another window which has to open attached with mainwindow not separately thats it ...this much i need to achieve initially.

veera

MS Sql also runs in Linux now ....that part already implemented now i need to implement ui as similar as ribbon control need to open multiple windows or widgets attached with mainwindow....

veera

How about the Qt Cascaded style sheets ,by using we can achieve ?

mrjj

Ok
So tasks are
1: Create ribbon like widget.
Try to use http://doc.qt.io/qt-5/qtabwidget.html#details
When it works, you can style it ( with stylesheets) to make it look more like an ribbon.
stylesheets from here http://developers-club.com/posts/48963/

2:

click it has to open the another window which has to open attached with mainwindow
What do you mean by attached here?
if you open a dialog with the mainwindows as parent, its both blocks the mainwindow and is
very attached to it.
void mainwindow::somebuttonpress() {
MyDialog dialog(this);
dialog.exec();
}

Thanks for your valuable reply.......if add any dialog designer class without button to my qt project if there is a pushbutton in mainwindow.ui after that dialog window is opening it separately...i don't want to open it has a seperate window .....that has to attached to mainwindow as a tab.......in screen sheet you can see it.......

during run time need to open the tabs like this please find my screen shot of the UI as like this ..... ,only minimum buttons like open button..... means need to open like this .....

mrjj

Ok but it has function for that.
http://doc.qt.io/qt-5/qtabwidget.html#addTab
so you can also do it run time.

veera

okay ....how to open the qtabs widget after pressing pushbutton from the mainwindow during the run time?

mrjj

@veera

you mean after you called addTab to add it ?

veera

No it has to call Qtabwidget with single tab...

veera

is it possible to implement ??

mrjj

Hi
Who has to call ?
You can use addTab to add a tab
and u show() to show it

Do you have the tabwidget in UI file?
You from button you just add tab.
Tab can be any widget you like.

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....

mrjj

@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.....

mrjj

@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.
