POwxWidgets - Add items to sizer via DLL
text
Body
copied!<p>I have a GUI set up with wxWidgets (C++, MSVC) and part of the functionality is to add elements to the GUI via DLL's. Essentially, I would be passing in a sizer to the DLL which will in turn add the elements based on what is in the DLL.</p> <p>Could someone just point me in the right direction on how to get the DLL set up? I have looked, but don't see anything that's similar to what I'm looking for. The programming of the elements is fine with me, I just need to understand how to structure the DLL programming.</p> <p>Help appreciated.</p> <hr> <p>UPDATE</p> <p>I've done something similar to <a href="http://wiki.wxwidgets.org/Programs_That_Support_Plugins" rel="nofollow">http://wiki.wxwidgets.org/Programs_That_Support_Plugins</a>.</p> <p>Essentially, I get Access violation reading location errors whenever I try using wxWidgets components from within the DLL.</p> <p>In the samplePlugin.cpp, If I use</p> <pre><code>void samplePlugin::PerformTasks() { wxMessageBox(_("I would if I could...")); } </code></pre> <p>I get the error. If, however, I use</p> <pre><code>void samplePlugin::PerformTasks() { MessageBox(0,"Testing this thing","Test",0); } </code></pre> <p>which is not wxWidgets, but rather native to the OS, the message box works fine.</p> <p>I've tried adding WXUSINGDLL;WXMAKINGDLL; in the Preprocessor Definitions in MSVC in both the DLL and the App projects. The DLL compiles fine, but I can't even compile the App in that case and get exceptions.</p> <p>Does anyone know how to fix this issue?</p>
