/**
|
||
|
|
A helper class making it possible to use system theme for any control.
|
||
|
|
|
||
|
|
Under MSW, there an alternative theme available for the list and list-like
|
||
|
|
controls since Windows Vista. This theme us used by Windows Explorer list
|
||
|
|
and tree view and so is arguably more familiar to the users than the standard
|
||
|
|
appearance of these controls.
|
||
|
|
|
||
|
|
This class is used in wxWidgets to enable this system theme in wxTreeCtrl,
|
||
|
|
wxListCtrl and wxDataViewCtrl and thus give them the same, familiar look.
|
||
|
|
It can also be used as a helper for implementing custom controls with the same
|
||
|
|
appearance. Notice that when using this class it is especially important
|
||
|
|
to use wxRendererNative::DrawItemSelectionRect() and
|
||
|
|
wxRendererNative::DrawItemText() to draw the control items to ensure that
|
||
|
|
they appear correctly under all platforms and Windows versions.
|
||
|
|
|
||
|
|
The following example shows implementation of a system theme enabled wxVListBox:
|
||
|
|
@code
|
||
|
|
#include <wx/systhemectrl.h>
|
||
|
|
|
||
|
|
class MyListCtrl : public wxSystemThemedControl<wxVListBox>
|
||
|
|
{
|
||
|
|
public:
|
||
|
|
MyListCtrl(wxWindow* parent)
|
||
|
|
{
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
EnableSystemTheme();
|
||
|
|
}
|
||
|
|
|
||
|
|
void OnDrawItem(wxDC& dc, const wxRect& rect, size_t n) const wxOVERRIDE
|
||
|
|
{
|
||
|
|
wxRendererNative::GetDefault().DrawItemText(this, dc, "Item #x", rect);
|
||
|
|
}
|
||
|
|
};
|
||
|
|
@endcode
|
||
|
|
|
||
|
|
On non-MSW platforms this class currently does nothing but is still
|
||
|
|
available, so that it can be used in portable code without any conditional
|
||
|
|
compilation directives.
