wxSystemThemedControl allows to use the "system theme" (i.e. the theme used by the system applications such as file manager and which can, surprisingly, be different from the default one). Currently it is only implemented for wxMSW and does nothing under the other platforms. Use wxSystemThemedControl for wxDataViewCtrl, wxListCtrl and, optionally, if wxTR_TWIST_BUTTONS style is specified, wxTreeCtrl to give them more native appearance under MSW. Closes #16414.

/**
|
|
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.
