"mainwindows" Example

[marcel]

STEPS:

1. qmake -project in mainwindows
2. qmake -project in the subfolders (if you deleted the makefiles and .pro files )
3. qmake in mainwindows
4. qmake in subfolders
5 make or nmake in mainwindows

Should work fine and generate all executables in the Release folders.

Hold on!

Calling "qmake -project" destroys a perfectly good project file. You musn't call it. Please bring it back from the original archive and then run qmake and make (without qmake -project).

"-o" option for qmake tells it how to name the Makefile and not where to redirect the messages.

since I ran qmake -project from its original folder I may have destroyed the original.

1) Is there another copy somewhere else?

I cant seem to find this mainwindows example on the Trolltech website. The example comes standard with Qt 4.2.3 (C:\Qt\4.2.3\examples\mainwindows).

2) Should Trolltech have this mainwindows example somewhere on their website?

Thanks in advance!!!

Yes, in a source archive available from for example www.trolltech.com Download the zip and replace the example files.

The top level project file looks as follows:

TEMPLATE      = subdirs
SUBDIRS       = application \
                dockwidgets \
                mdi \
                menus \
                recentfiles \
                sdi
 
# install
target.path = $$[QT_INSTALL_EXAMPLES]/mainwindows
sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS mainwindows.pro README
sources.path = $$[QT_INSTALL_EXAMPLES]/mainwindows
INSTALLS += target sources

TEMPLATE      = subdirs
SUBDIRS       = application \
                dockwidgets \
                mdi \
                menus \
                recentfiles \
                sdi

# install
target.path = $$[QT_INSTALL_EXAMPLES]/mainwindows
sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS mainwindows.pro README
sources.path = $$[QT_INSTALL_EXAMPLES]/mainwindows
INSTALLS += target sources

To copy to clipboard, switch view to plain text mode 

If you didn't ruin project files in subdirectories, this is all you need.

Good progress (I think)!! I went into archive and got a new "mainwindows" example file and ran qmake and make only and it looks like everything ran smoothly. Thanks for that help!

But where is the executable? There is no DEBUG or RELEASE folder under the mainwindows folder.

There is a RELEASE folder in every subfolder (application, dockwidgets, mdi, menus, etc...) that has an executable but I those dont seem seem to work when ran.

I am wonding if only running qmake and make in the mainwindows folder is all I have to do?

Or do I need to go into every subfolder and run qmake and make?

"mainwindows" contains a set of examples in subdirectories. You need Qt libraries to be accessible to run them. Either place Qt libs in a path where your system looks for dlls (like C:\WINDOWS\System) or copy them to the same directory where each executable resides. Then you'll be able to run them.

Wysota, okay went into C:\Qt\4.2.3\lib and opended up the README file.

The README file says "If this directory is empty, you probably forgot to compile the Qt library." My README directory (file) is empty. Is this a cause of my problems? If so, how do I compile the Qt Libraries?
