Documentation:

||||
|
||||
The MarginView is designed to be a self contained component that manages
|
||||
the display of a BBox control that shows a graphic of a page and its'
|
||||
margings. The component also includes text fields that are used to mofify
|
||||
the margin values and a popup to change the units used for the margins.
|
||||
|
||||
There are two interfaces for the MarginView component:
|
||||
|
||||
1) Set methods:
|
||||
- page size
|
||||
- orientation
|
||||
|
||||
Get methods to retrieve:
|
||||
- margins
|
||||
- page size
|
||||
|
||||
The method interface is available for the parent Component to call on
|
||||
the MarginView in response to the Window receiveing messages from
|
||||
other BControls that it contains, such as a Page Size popup. The
|
||||
Get methods are used to extract the page size and margins so that
|
||||
the printer driver may put these values into a BMessage for printing.
|
||||
|
||||
2) 'Optional' Message interface:
|
||||
- Set Page Size
|
||||
- Flip Orientation
|
||||
|
||||
The message interface is available for GUI Controls, BPopupMenu to send
|
||||
messages to the MarginView if the parent Window is not used to handle
|
||||
the messages.
|
||||
|
||||
General Use of MarginView component:
|
||||
|
||||
1) Simply construct a new MarginView object with the margins
|
||||
you want as defaults and add this view to the parent view
|
||||
of the dialog.
|
||||
|
||||
MarginView *mv;
|
||||
mv = new MarginView(viewSizeRect, pageWidth, pageHeight);
|
||||
parentView->AddChild(mv);
|
||||
|
||||
* you can also set the margins in the constructor, and the units:
|
||||
|
||||
mv = new MarginView(viewSizeRect, pageWidth, pageHeight
|
||||
marginRect, kUnitPointS);
|
||||
|
||||
! but remeber to have the marginRect values match the UNITS :-)
|
||||
|
||||
2) Set Page Size with methods:
|
||||
|
||||
mv-SetPageSize( pageWidth, pageHeight );
|
||||
mv->UpdateView();
|
||||
|
||||
3) Set Page Size with BMessage:
|
||||
|
||||
BMessage* msg = new BMessage(CHANGE_PAGE_SIZE);
|
||||
msg->AddFloat("width", pageWidth);
|
||||
msg->AddFloat("height", pageHeight);
|
||||
mv->PostMessage(msg);
|
||||
|
||||
4) Flip Page with methods:
|
||||
|
||||
mv-SetPageSize( pageHeight, pageWidth );
|
||||
mv->UpdateView();
|
||||
|
||||
5) Flip Page with BMessage:
|
||||
|
||||
BMessage* msg = new BMessage(FLIP_PAGE);
|
||||
mv->Looper()->PostMessage(msg);
|
||||
|
||||
Note: the MarginView DOES NOT keep track of the orientation. This
|
||||
should be done by the code for the Page setup dialog.
|
||||
|
||||
6) Get Page Size
|
||||
|
||||
BPoint pageSize = mv->GetPageSize();
|
||||
|
||||
7) Get Margins
|
||||
|
||||
BRect margins = mv->GetMargins();
|
||||
|
||||
8) Get Units
|
||||
|
||||
uint32 units = mv->GetUnits();
|
||||
|
||||
where units is one of:
|
||||
kUnitInch, 72 points/in
|
||||
kUnitCM, 28.346 points/cm
|
||||
kUnitPoint, 1 point/point
