I'm trying to create a simple dialog box following the exam at
http://dev.chromium.org/developers/design-documents/views-windowing.
Note that I'm using views as in a standalone app (I'm not embedding
this dialog in Chromium).
I've added 2 views::Textfields to WindowView, but I can't seem to tab
between them. When I press the tab key, it simply inserts a tab into
the editbox.
Here is what I have:
<snip>
#pragma once
#include "views/controls/textfield/textfield.h"
#include "views/view.h"
#include "views/window/dialog_delegate.h"
namespace views {
class Label;
class Textfield;
}
class WindowView : public views::View,
public views::DialogDelegate,
public views::Textfield::Controller {
public:
WindowView();
~WindowView();
// Overridden from views::View:
virtual void Paint(gfx::Canvas* canvas);
virtual void Layout();
virtual gfx::Size GetPreferredSize();
// Overridden from views::DialogDelegate:
virtual std::wstring GetWindowTitle() const { return L"Demo"; }
virtual bool CanResize() const { return true; }
virtual bool CanMaximize() const { return true; }
virtual views::View* GetContentsView() { return this; }
virtual int GetDialogButtons() const { return
MessageBoxFlags::DIALOGBUTTON_OK; }
// Return the view that you want to have initially focused
virtual views::View* GetInitiallyFocusedView();
private:
// Overridden from views::Textfield::Controller:
virtual void ContentsChanged(views::Textfield* sender,
const std::wstring& new_contents);
virtual bool HandleKeystroke(views::Textfield* sender,
const views::Textfield::Keystroke&
keystroke);
views::Label* label1_;
views::Textfield* textbox1_;
views::Label* label2_;
views::Textfield* textbox2_;
DISALLOW_COPY_AND_ASSIGN(WindowView);
};

What am I doing wrong?
