How to get cursor position in status bar?

Vladislav Gospodinov

Hello...This question may sound silly to some of you but I've been stuck on it for few days and can't find any answer... So I need to have the mouse position x and y displayed in the status bar. So far I add new string to the table, in the indicators array, afx_msg void OnUpdateCurPos(CCmdUI *pCmdUI) in the message map and ON_UPDATE_COMMAND_UI(ID_INDICATOR_CURSOR,OnUpdateCurPos) When I run it's there but can't find the right way to update the cords. I think it must work with ON_MOUSEMOVE func...I've tried several codes in ON_MOUSEMOVE and OnUpdateCurPos but it doesn't work at all... Working with SDI.

What does your OnUpdateCurPos() and OnMouseMove() functions look like? Have you called SetCapture()?

Well that is the problem :P I've added SetCapture() when you press LButton, but I'm not rly sure if I need it?

void CMainFrame::OnLButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
SetCapture();
CFrameWnd::OnLButtonDown(nFlags, point);
}

void CMainFrame::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
if(GetCapture()==this){
posX=point.x;
posY=point.y;
}
CFrameWnd::OnMouseMove(nFlags, point);
}

void CMainFrame::OnUpdateCursor(CCmdUI *pCmdUI){
CString pos;
pos.Format(ID_INDICATOR_CURSOR,posX,posY);
m_wndStatusBar.SetPaneText(m_wndStatusBar.CommandToIndex(ID_INDICATOR_CURSOR),pos);
}

Well atleast now the sting is updated with 0's. Its defined as " x: %d ,y: %d ". So the OnUpdateCursor() is working but not with the right values...

What happens when you change your Format statement to

pos.Format(" x: %d ,y: %d " ,posX,posY);

Vladislav Gospodinov

Nothing. Stays the same:

"x: 0 , y: 0"

It that the value of pos immediately after the Format() call?

Vladislav Gospodinov

Yes... Seems like OnMouseMove doesn't update posX and posY. If I do :

void CMainFrame::OnUpdateCursor(CCmdUI *pCmdUI){
CString pos;
posX=100;
posY=200;
pos.Format(L" x: %d ,y: %d ",posX,poxY);
m_wndStatusBar.SetPaneText(m_wndStatusBar.CommandToIndex(ID_INDICATOR_CURSOR),pos);
}

It does put

"x: 100,y: 200"

in the status bar...

So, it looks like GetCapture() != this, perhaps have a look at this[^] article.

In OnMouseMove(), what is the value of point.x and point.y?

I can't rly get the debuger to stop there ... It's kinda like skipping it all? Any other way of checking ?

Try this!

void CDlgStatusBarDlg::OnMouseMove(UINT nFlags, CPoint point)
{
CString s;
s.Format("X=%d Y=%d",point.x,point.y);
m_bar.SetPaneText(0,s);
CDialog::OnMouseMove(nFlags, point);
}

TRACE().

So it doesn't TRACE() anything at all when called in

CMainFrame::OnMouseMove

so it's like it doesn't get the mouse moving at all in MainFrame class... it does trace correct values if I call it in the View class

CpositionView::OnMouseMove

however I can't find a way to send them from View to MainFrame, although I have included ***View.h and taka them like

CpositionView::positionX

I get a lot of errors :P
