Errata for Cross-Platform GUI Programming with wxWidgets
Errors will be corrected in future reprints. Please report errors to Julian Smart at firstname.lastname@example.org.
Error on P. xii
At the top of the page, the page reference “31” should read “131”.
Error on P. 1 Reported 2006-09-21
At the end of the first paragraph, “available parts” should read “available ports”.
Error on P. 52

Error on P. 63
Figure 4-5 repeats the MDI screenshot from Figure 4-6, and should instead show the following picture.
Error on P. 72
In the example code for the wxPanel, this code:
wxPanel* panel = new wxPanel(frame, wxID_ANY, wxDefaultPosition, (500,300));
wxPanel* panel = new wxPanel(frame, wxID_ANY, wxDefaultPosition, wxSize(500,300));
Error on P. 73
wxNotebook *notebook = new wxNotebook(this, wxID_ANY, wxDefaultPosition, wxDefaultSize); wxImageList *imageList = new wxImageList(16,16,true, 3); imageList->Add(wxIcon(copy_xpm)); imageList->Add(wxIcon(paste_xpm)); imageList->Add(wxIcon(cut_xpm)); wxPanel1 *window1 = new wxPanel(notebook, wxID_ANY); wxPanel2 *window2 = new wxPanel(notebook, wxID_ANY); wxPanel3 *window3 = new wxPanel(notebook, wxID_ANY); notebook->AddPage(window1, wxT("Tab One"), true,0); notebook->AddPage(window2, wxT("Tab two"), false,1); notebook->AddPage(window3, wxT("Tab three"), false,2);
should instead read:
wxImageList *imageList = new wxImageList(16,16,true, 3); imageList->Add(wxIcon(copy_xpm)); imageList->Add(wxIcon(cut_xpm)); imageList->Add(wxIcon(paste_xpm)); notebook->SetImageList(imageList); wxPanel *window1 = new wxPanel(notebook, wxID_ANY); wxPanel *window2 = new wxPanel(notebook, wxID_ANY); wxPanel *window3 = new wxPanel(notebook, wxID_ANY); notebook->AddPage(window1, wxT("Tab One"), true,0); notebook->AddPage(window2, wxT("Tab two"), false,1); notebook->AddPage(window3, wxT("Tab three"), false,2);
(remove numbering from wxPanel1, wxPanel2, and wxPanel3, add a SetImageList call, switch the ordering of the paste_xpm and cut_xpm lines to match the ordering of the tab icons in Figure 4-9, and add a comma between “false” and “2” on the last line.)
Error on P. 77
In the first example, the lines
int pixelsPerUnixX = 10; int pixelsPerUnixY = 10;

(change Unix to Unit).
Error on P. 94 Reported 2007-11-20

Also, the spacing in the example is wrong, and should be:
// Draw a green rectangle outlined in red dc.SetPen(*wxRED_PEN); dc.SetBrush(*wxGREEN_BRUSH); dc.DrawRectangle(10, 10, 100, 100); // Now fill the green area with black (while green is found) dc.SetBrush(*wxBLACK_BRUSH); dc.FloodFill(50, 50, *wxGREEN, wxFLOOD_SURFACE); // Then fill with blue (until red is encountered) dc.SetBrush(*wxBLUE_BRUSH); dc.FloodFill(50, 50, *wxRED, wxFLOOD_BORDER);
