[Qgis-developer] Plugin Development C++ Windows - Any response? Just enough!

Fri Feb 25 13:04:29 EST 2011

Thank you all for the guidance you provided. I was able to run the plugin_buidler.py to generate the base C++ files. I was also able to generate the visual c++ project files by using cmake-gui and you may even be surprised to hear that it compiled with out complaining and telling me it is offended by such and such item, etc. Where that leads me is still not clear but I have no complaints right now, just thanksgiving.

Hi devs,
I also had problems to get the startup on c++ plugins development. Mainly because there was no Plugin Builder for C++. So we had to write everything from scratch and many are repetitive tasks. 
I though about writing a plugin builder for c++ but it never got out of planning phase. Anyone interested in developping?

Best regards,
Mauricio

Maaza - once you have QGIS building from source in windows the process

for building a new plugins is quite simple. Just copy and paste a

simple plugin folder like copyright plugin, name the folder something

like myplugin or whatever and then work through each and every file in

that dir (using search and replace where it makes sense to do so) to

make it your own. Look in the CMakeLists.txt - its not that hard -

typically you just need to add your .h and .cpp files to the list. If

you are able to use linux, you can even more easily just use the

plugin_builder.py script in that src/plugins directory and it will

generate for you a 'hello world' C++ plugin.

All that said you will need to understand Qt4 to do anything useful

once you get going...

Have fun!

Regards

Tim
