well,that's hard to describe,let's see some code:
in main.cpp:
struct App : public TopWindow
{
ULeftCtrl Left;
URightCtrl Right;
....
CppSQLite3DB database;//that is another
String exeDML(const char* szSQL);
//this routine to parse szSQL and record every INSERT or UPDATE with acture ROWID.
....
}
GUI_APP_MAIN
{
App().Run();
}
in LeftCtrl.h(represent Left Pane) somewhere
want to call database.xxx and exeDML()
==================================================
static Vector<Ctrl *> Ctrl::GetTopCtrls();
static Vector<Ctrl *> Ctrl::GetTopWindows();
is that get App struct?
if not this not help,I can define database pointer in LeftCtrl.h and then in App::App() make this pointer point to database,but I got no idea with exeDML.I have to consider trigger or some other way.
