In addition to reporting the mouse events in the implementation of MouseEventHandler,
the native window can be dragged by pressing the left mouse button. To realize this feature
we register WM_MOVE and move the window to its new position with SetWindowPos().
// MouseEventHandler.cpp
#include "MouseEventHandler.h"
// ----------------- Selector -------------------------------WindowHandler *
selectWindowHandler(JNIEnv * env, jobject obj, int select)
{
return new MouseEventHandler(env, obj);
}
// ----------------- class MouseEventHandler ---------------// Constructor, initialize base class
MouseEventHandler::MouseEventHandler(JNIEnv * env,
jobject obj)
: WindowHandler(env, obj)
{}
// Select which windows message will call evMsg()
bool MouseEventHandler::wantMsg(UINT uMsg)
{
return (uMsg == WM_CREATE ||
WM_LBUTTONDOWN ||
WM_LBUTTONUP ||
WM_LBUTTONDBLCLK ||
WM_MOVE ||
WM_PAINT ||
WM_DESTROY);
}
// Event procedure
// Return false, if message is handled by this procedure,
// true to invoke DefWindowProc()
bool MouseEventHandler::evMsg(HWND hWnd, UINT message,
WPARAM wParam , LPARAM lParam)
