i painted the line using a and b by mfc.
for example,

        CStatic* stc = (CStatic *)GetDlgItem(IDC_STATIC_ENERGY); // i want to draw in ID_PANEL1, instead of IDC_STATIC_ENERGY
	CRect rect;

	CClientDC dc(stc);
	stc->GetClientRect(&rect);
	CBrush brush;
	brush.CreateSolidBrush(RGB(255, 255, 255));
	FillRect(dc, &rect, brush);

	dc.MoveTo(0, rect.bottom/2);
		for (int n=0; n<frameN; n++)
		{
			//dc.LineTo(n/amp_scale2,2*feature2d[n][0]);
			dc.LineTo(n,2*feature2d[n][0]);
		}
		brush.DeleteObject();

As I tried to draw the data in the wxWidgets.
While reading the Reference, one by one, is not easy to learn.
please teach me about draw data(line) by wxwidgets.

This shows you how a create a wxPanel for custom drawings:
https://wiki.wxwidgets.org/Drawing_on_a_panel_with_a_DC

And this is the reference for wxDC:
http://docs.wxwidgets.org/trunk/classwx_d_c.html

Most method names are similar to MFC.

i make source in mfc about connect CRect with CClientDC.
CStatic* stc = (CStatic *)GetDlgItem(IDC_STATIC_ENERGY);
CRect rect;
CClientDC dc(stc);
stc->GetClientRect(&rect);

hm....Perhaps, if i connect wxRect and wxclient, i can draw data..

wxRect rect;
wxClientDC dc(Panel1);

but I failed to find about connect wxRect and wxclient in Reference.
How should the connection?

Code: Select all

wxRect rect = Panel1->GetRect();
