Programs Using Wxwidgets Hello
Installation guideI know this is a old question but I struggled really hard to find a guide for an installation on wxwidgets. You can use the vckpg importer by Microsoft. Make sure you have git installed before you follow this routine. I will write this for Windows with Visual Studio 2017:. Clone the following repository to a directory of your choice:git clone. Then open up powershell (ps) (run it as admin) and navigate to the cloned vcpkg folder.Now in ps, while you are in the vcpkg folder run the following command.vcpkg integrate install so we have a user-wide integration of the vcpkg paket manager and can #include libraries in our c projects.Now to install wxwidgets 32-Bit run.vcpkg install wxwidgets -triplet x86-windows.
For the 64-Bit Version run.vcpkg install wxwidgets -triplet x64-windows. Now open up the properties of your project in Visual Studio. For the integration of the 64-Bit wxwidgets version choose all configurations and as plattform x64.

Then go to C/C - General - Additional Include Directories and add the following folderpath YOURFOLDERPATHvcpkgpackageswxwidgetsx64-windowsinclude;YOURFOLDERPATHvcpkgpackageswxwidgetsx64-windowslib. Do the same for the x86 configuration but with the wxwidgetsx86-windows folderpath instead. As a last step go to in the properties under C/C - Preprocessor and under the point Preprocessordefinition add the following as extra point WXUSINGDLL=1 (do it for the x64 and for the x86 plattform configuration if you want to use both)Now you should be able to use the library and run the hello world project.
HelloWorldApp & app =:: wxGetApp ;You could be wondering why the frame variable isn't deleted anywhere. By setting the frame as the top window of the application, the application will delete the frame for us (for a more in-depth explanation, see ).Some broken compilers don't allow NULL to be casted to wxFrame. implicitly, so that's why we do it explicitly, just to be on the safe side. Really? Is this true even now? The C standard (which is 5 years old now) requires that NULL, which is 0 (or 0L, or 0s - but not (void.)0) can be cast to any pointer type.
Even MSVC 6 gets this right - anyone using such a broken compiler should probably upgrade.After the frame is constructed, a statusbar is created with the CreateStatusBar method. The text of the statusbar is set to 'Hello World'. Calling Show shows the frame.
Show is a method of the wxWindow class which wxFrame derives from.When OnInit returns false, the application immediately stops. This way you can stop the application when something went wrong during the initialization phase.Thanks to Franky Braem for the initial content for this pageCompilingTo compile under linux using g, use the following command:g HelloWorldApp.cpp `wx-config -libs` `wx-config -cxxflags` -o HelloWorldApp.
