Hi,

I'm trying to create a 'static-linked plugin system' like is done for e.g. plugin/bmp and plugin/png. The plugins should provide a GUI to allow the users to set some configuration. Providing the controls works for buttons, but adding a treectrl results in a distorted UI (the text in the provided is not centered anymore) and a memory leak.

What am I doing wrong? Is this not supported or is this a bug somewhere in the upp code?

For an example see the code below.

Best regards,

Martin

#include <CtrlLib/CtrlLib.h>
using namespace Upp;

/* Plugins */
static StaticCriticalSection sAnyStoragePlugin;
class StoragePlugin {
	typedef StoragePlugin *(*StorageFactory)();
	template <class T> static StoragePlugin *FactoryFn() { return new T; }
	static void AddPlugin(StorageFactory f) { INTERLOCKED_(sAnyStoragePlugin)Map().Add(f()); }
	static Array<StoragePlugin>& Map() { static Array<StoragePlugin> x; return x; }

public:
	template <class T> static void Register() { AddPlugin(&StoragePlugin::FactoryFn<T>); }
};

class DiskStorage : public StoragePlugin {
	TreeCtrl  c;  // <<<< Comment me to get a correct GUI and remove the memory leak
	Button    b;
};

INITBLOCK {
	StoragePlugin::Register<DiskStorage>();
}

/* App */
class DeBunny : public TopWindow {
	Button button;
	    
public:
	typedef DeBunny CLASSNAME;
	DeBunny() {
            Add(button.SetLabel("&I'm an Ultimate++ button!").VCenterPos(20).HCenterPos(200));
	};
};

GUI_APP_MAIN
{
	DeBunny().Run();
}
