no error???? why???

[Shuchi Agrawal]

thanks Cesar but i m able to do it correctly.so my ques was that why the given code does not give error as there is no slot in Ui::MainWindow and when QmessageBox class has not been included, still its not showing error. why??????

[jpn]

Signal slot connections are established at run time. You won't get compilation errors if you misspell something in the connect statement (unless the typo is so bad that it doesn't pass syntactically). The connect statement returns false if the connection fails (and in this case it does print information on the debug output):

Object::connect: No such slot MainWindow::ui.disp()
Object::connect: (sender name: 'pushButton')
Object::connect: (receiver name: 'MainWindow')

You are including the whole QtGui module which leads to including QMessageBox as well.

Are you running the program in Visual Studio? It should appear in the debug output window.

and can u tel me the way to draw line n all on central widget and

Override QWidget::paintEvent() for the widget you want to paint on and use QPainter to draw the line. For example, if you want to paint on the central widget in a main window, you must reimplement the paintEvent() for the central widget, not for the main window.

activate context menu(floating menu)

See this post.

The commercial edition of Qt has at least some loose integration to VS6.
Presumably you have the commercial edition of Qt so try downloading and installing the Qt-VsAddin package. The package should give you some tools for managing Qt project directly from VS.

Another solution is to add "CONFIG += console" to the .pro file to make an additional console window appear for the debug output.

and is the moveDockWindow is the same for Floating window in qt4 or is there some other function or class for same?

You need to always re-run qmake after modifying the .pro file to generate a new makefile. Did you, by any chance, forget that step?

What do you mean by "moveDockWindow"? For example the "Sidebar" in Qt Designer is a QDockWidget. Did you mean that?

I can see two Qt3Support methods called "moveDockWindow":

• Q3MainWindow::moveDockWindow()
• Q3DockArea::moveDockWindow()

Do they have something to do with this? Please be specific with the terms and class names you use. It will be easier for others to interpret the meaning of the post.

i have atached them now.

yes i mean with sidebar only which is QDockWidget class in Qt.
thanks

AFAIK == As Far As I Know

for integrating Qt with Visual Studio check this

I have integrated Qt Open Source edition with Visual Studio 2005. But yes designer is not integrated , u have to copy the ui files and compile.
hope this helps

AFAIR you can't recompile the evaluation version, so configure.exe isn't shipped with it.

Bah sorry, it's reading right there in the first post that you are using an evaluation version. Actually, I have no clue if the evaluation version contains the Qt VsAddin package (which is the only official way to integrate Qt4 into VS6). Can anyone confirm whether it does or not? Sorry for the confusion.

AFAIK it does.

hey jpn,

form.cpp
form.h
form.ui

above are the code.so check them n tel tht is it the right way to paint(draw line n a point) on the central widget on a menu click event?[i think its not the right way, though its working]

by floating window i mean the sidebar which u can see on paint application and which can be dragged to any part of the paint window.
plz see to it..
thaks in advance
