Newbie to Winapi.Learnt the basics of winapi and tips of creating child window in firebreath plugin.
Searched tutorials,got answers.But don't know What Am i Doing wrong here? Following is my code>>My main objective is to create a textbox functioning like that in MSWord on aparent plugin(windowed firebreath plugin) window handle whereby I can edit,modify the text as well as move and resize the textbox.Also, I am not able to fire many events like WM_LBUTTONDOWN and more on the child window.
int WINAPI childwindow::LoadForm()
{
HWND pluginWnd=win->getHWND();
HINSTANCE pluginInstance = (HINSTANCE)GetWindowLong(pluginWnd, GWL_HINSTANCE);
HWND demoWnd = CreateWindowEx(WS_EX_CLIENTEDGE, TEXT("Edit"),TEXT("text to be written"),WS_CHILD|WS_VISIBLE|
ES_MULTILINE|ES_AUTOVSCROLL|ES_AUTOHSCROLL|WS_BORDER|WS_VSCROLL|WS_HSCROLL, 10, 10, 300, 100, pluginWnd, (HMENU)IDC_MAIN_EDIT, pluginInstance , NULL);
//SUBCLASSING=============REFERENCE>>(http://cboard.cprogramming.com/windows-programming/148771-subclassing-edit-box.html)
PreviousSubclassedEditProc=(WNDPROC)GetWindowLong(demoWnd, GWL_WNDPROC);//WNDPROC PreviousSubclassedEditProc;
SetWindowLong(demoWnd, GWL_WNDPROC,(LONG_PTR)&childwindow::CustomWinProc);
SetWindowText(demoWnd,_T("LALALA"));
//======================
ShowWindow(demoWnd, SW_SHOWNORMAL);
UpdateWindow(demoWnd);
return EXIT_SUCCESS;
}
LRESULT CALLBACK childwindow::CustomWinProc( HWND chWnd, UINT uMsg, WPARAM wParam, LPARAM lParam )
{
HWND textBoxInput,button,tempHandle=0;
HINSTANCE hInstance = (HINSTANCE)GetWindowLong(chWnd, GWL_HINSTANCE);
switch(uMsg)
{
case WM_CREATE:
{
return 0;
break;
}
case WM_MOUSEACTIVATE:
{
SetFocus(chWnd);
break;
}
case WM_DESTROY:
{
PostQuitMessage(0);
return 0;
}
case WM_LBUTTONDOWN:
{
dragWindow = true;
tempHandle=SetCapture(chWnd);
break;
}
case WM_LBUTTONUP:
{
ReleaseCapture();
tempHandle=NULL;
dragWindow = false;
break;
}
case WM_MOUSEMOVE:
{
if(dragWindow==true)
{
RECT mainWindowRect;
POINT pos;
int windowWidth, windowHeight;
pos.x = (int)(short) LOWORD(lParam);
pos.y = (int)(short) HIWORD(lParam);
GetWindowRect(chWnd,&mainWindowRect);
windowHeight = mainWindowRect.bottom - mainWindowRect.top;
windowWidth = mainWindowRect.right - mainWindowRect.left;
ClientToScreen(chWnd, &pos);
SetWindowPos(chWnd, NULL, pos.x, pos.y, windowWidth,windowHeight, SWP_NOZORDER);
ShowWindow(chWnd,SW_SHOWNORMAL);
}
break;
}
case WM_KILLFOCUS:
{
LPCWSTR buffer[1024];
SendMessage(chWnd,
WM_GETTEXT,
sizeof(buffer)/sizeof(buffer[0]),
reinterpret_cast<LPARAM>(buffer));
break;
}
default:
{
return DefWindowProc(chWnd,uMsg,wParam,lParam);
}
}
return TRUE;
}
The above child window is being made on a parent windowed firebreath plugin handle.
I also want to get the text from the child textbox window.but that's not possible till I get this right.I saw one google grouptutorials and this which has helped me a lot to get the basics.But the above problem is bugging me from last day.
Any takers for this question?
