which ide/editor/database work best with qt4?

[Brandybuck]

The standard reply is "use whatever tools you like best". Do you have an IDE you like? Then use it! I know people successfully using Qt with dev-c++, Eclipse, Visual Studio, KDevelop, XCode and plain old Emacs. Use what you like!

It's not our job to tell you what you should like!

But I would caution you NOT to get too attached to one tool. Use whatever tools you want, but also know how to survive without them. A competent programmer can survive with just a shell and text editor if necessary.

cool!!! i like the way u answer my doubts

i have plenty of tools, dev-c++, borland c++ builder 5.5, visual c++... and i never found out which i prefer the most

but i think i'll use borland c++ 5.5 compiler and notepad++ editor, so, how to make these become good friends with QT4? i do hope that borland c++, qt, and sqlite3 can be very good couples

i'm now buckle up, u take the wheel, and show me the wondorous of the QT world

Get the new "C++ GUI Programming with Qt 4" book if you can. Otherwise the tutorials that come with Qt should be sufficient. Notepad++ is a good editor.

why? there are modifications between qt3 and qt4?

i just change my mind, i will use notepad++ as my editor and i just compile it from command prompt, easiest way!

thanks for the help

now another problem arise

#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QPushButton hello("Hello world!");
hello.resize(100, 30);

hello.show();
return app.exec();
}

when i make, the following message scared me

C:\Qt\4.1.4\hello>qmake -project

C:\Qt\4.1.4\hello>qmake

Do you have the Qt debug libraries built? It looks like you don't.

[kkool84]

i did, but after half an hour, the build debug libraries still stuck at the same place, i guessed it is done, so, i close the prompt

run again now, hope it finish soon

oh, man, qt is load more fun than i thought

[kkool84]

i have mingw 5.0.3 install in my notebook by the default path, when i install qt, it tolds me that it cannot find "w32api.h" in my mingw, what is wrong with that?

i ignore the message and install it anyway, then i begin to build debug libraries, it stuck at qtmd5.cpp, after half an hour, it is still at the same place, and what the hxxx is wrong with that?

That file contains the Win32 API. You need it. It is supposed to come with MinGW. Did you install MinGW before you installed Qt? Qt specifically looks for this file when it is installed.

This is very strange. I haven't seen an error like that in years. I think you may have a bad installation of MinGW. Try installing it again. If it still doesn't work, I would consider posting detailed information on the problem to qt-interest mailing list.

i had mingw installed before i proceed to qt!!!!! and i stuck again ORZ

i uninstalled qt, mingw, and install again, qt by using qt's downloaded mingw, everything seems perfect

but, u know, i stuck when i build debug libraries, for half an hour, nothing happen

Really nothing? Is your CPU idle? Qt compilation can take even few hours.

uh-oh, not a damn thing after 1hour
i try to install on my another centrino notebook, works fine, too fine.
when i work on this centrino duo, not working. i installed and uninstalled and again and again and again...........and again. it just stuck in the build debug libraries.

[jacek]

it just stuck in the build debug libraries.

Maybe you don't have enough free space on your hard drive? How much RAM do you have?
