If the child widgets are larger than the size + of this object then scrollbars will appear so that you can scroll over + to them: + \image html Fl_Scroll.png + \image latex Fl_Scroll.png "Fl_Scroll" width=4cm + + If all of the child widgets are packed together into a solid + rectangle then you want to set box() to FL_NO_BOX or + one of the _FRAME types. This will result in the best output. + However, if the child widgets are a sparse arrangement you must + set box() to a real _BOX type. This can result in some + blinking during redrawing, but that can be solved by using a + Fl_Double_Window. + + By default you can scroll in both directions, and the scrollbars + disappear if the data will fit in the area of the scroll. + + Use Fl_Scroll::type() to change this as follows : + <UL> + <LI>0 - No scrollbars </LI> + <LI>Fl_Scroll::HORIZONTAL - Only a horizontal scrollbar. </LI> + <LI>Fl_Scroll::VERTICAL - Only a vertical scrollbar. </LI> + <LI>Fl_Scroll::BOTH - The default is both scrollbars. </LI> + <LI>Fl_Scroll::HORIZONTAL_ALWAYS - Horizontal scrollbar always on, vertical always off. </LI> + <LI>Fl_Scroll::VERTICAL_ALWAYS - Vertical scrollbar always on, horizontal always off. </LI> + <LI>Fl_Scroll::BOTH_ALWAYS - Both always on. </LI> + </UL> + + Use <B> scrollbar.align(int) ( see void Fl_Widget::align(Fl_Align) ) :</B> + to change what side the scrollbars are drawn on. + + If the FL_ALIGN_LEFT bit is on, the vertical scrollbar is on the left. + If the FL_ALIGN_TOP bit is on, the horizontal scrollbar is on + the top. Note that only the alignment flags in scrollbar are + considered. The flags in hscrollbar however are ignored. + + This widget can also be used to pan around a single child widget + "canvas". This child widget should be of your own class, with a + draw() method that draws the contents. The scrolling is done by + changing the x() and y() of the widget, so this child + must use the x() and y() to position its drawing. + To speed up drawing it should test fl_push_clip(). + + Another very useful child is a single Fl_Pack, which is itself a group + that packs its children together and changes size to surround them. + Filling the Fl_Pack with Fl_Tabs groups (and then putting + normal widgets inside those) gives you a very powerful scrolling list + of individually-openable panels. + + Fluid lets you create these, but you can only lay out objects that + fit inside the Fl_Scroll without scrolling.
