I propose something like:
enum ViewMode
{
viewmode_PageLayout,
viewmode_Normal,
viewmode_Outline
};
(excuse my syntax, i haven't used enums in years.)
In the document class, under public: (or protected: if a GetViewMode ()
function is implemented publically):
ViewMode mDocMode;
this variable is linked to the set of menu items (that havent been
implemented yet) that select view mode.
This becomes usefull, for example, in the margin code:
mMarginSizeX = 0;
mMarginSizeY = 0;
if (mDocMode != viewmode_Normal)
{
mMarginSizeX = x;
mMarginSizeY = y;
// set up margin widgits ...
}
where x and y are #define'd constants with default margin size and
mMarginSizeX and Y are hypothetical member variables that define the size
of the margins.
I havent looked very much at the source, but this would make it way
easier to have alternative views.
