[SOLVED]Help on QDialog..

M_31

I have created a dialog window (ui_TestDlg) without any class definition. i mean without (TestDlg.cpp & TestDlg.h) files, just a design form alone.

And I have only ui_TestDlg.h file . I just want to show this UI form from my MianWindow ( mainwindow.cpp).
Becoz i am not going to do any operation on this Dialog window.

I tried several ways to find show() or exec() menthod of this ui_testDlg ...but i am not able to get the same..

the sample codes are here

@
// mainwindow.h
Ui_TestDlg *ui_tstDlg;

//mainwindow.cpp
ui_tstDlg=new Ui_FindComputersDlg;
///ui_tstDlg.show(); ---- this function is not available ...

The information you are providing is not sufficient to give any decent comment or advice.

However, I would suggest that you are using Qt creator to setup the dialog box and try from there.
Also you could start with the "dialog examples":http://doc.qt.nokia.com/4.7/examples-dialogs.html as an entry point.

Of course that function isn't available. An Ui class isn't a QWidget. See here:

If you want to just show something, you might consider using QSplashScreen.

For this dialog, though, try:

Add namespace declaration to mainwindow.h:
@namespace Ui {
class Ui_TestDlg;
}@
Initialise the dialog with (new Ui::Ui_TestDlg)
Call ui_tstDlg.setupUi(QObject *parent).

Might work, although it's just a quick thought and I may have missed something important.
