Description

+ This container widget lets you maneuver around a set of widgets much +larger than your window. If the child widgets are larger than the size +of this object then scrollbars will appear so that you can scroll over +to them: +

Fl_Scroll widget.

+

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 arrangment 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.

+

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 it's 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 it's 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. Be sure to leave +space for the scrollbars, as Fluid won't show these either.

+

You cannot use Fl_Window as a child of this since the +clipping is not conveyed to it when drawn, and it will draw over the +scrollbars and neighboring objects.

+

Fl_Scroll widgets should not be nested. Having an Fl_Scroll +inside another Fl_Scroll may result in drawing errors when resizing.

+

Methods

+ +

Fl_Scroll::Fl_Scroll(int x, int y, int +w, int h, const char *label = 0)

+ Creates a new Fl_Scroll widget using the given position, +size, and label string. The default boxtype is FL_NO_BOX. +

virtual Fl_Scroll::~Fl_Scroll()

+ The destructor also deletes all the children. This allows a +whole tree to be deleted at once, without having to keep a pointer to +all the children in the user code. A kludge has been done so the +Fl_Scroll and all of it's children can be automatic (local) +variables, but you must declare the Fl_Scrollfirst, so +that it is destroyed last. +

void Fl_Widget::type(int)

+ By default you can scroll in both directions, and the scrollbars +disappear if the data will fit in the area of the scroll. type() + can change this: + + +

void Fl_Scroll::scrollbar.align(int)

+ This is used 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. + +

Fl_Scroll::bbox(int &x, int &y, int &w, int &h)

+ +

[protected] This method returns the bounding box for the interior of the scrolling +area, inside the scrollbars. + +

int Fl_Scroll::xposition() const

+ Gets the current horizontal scrolling position. + +

int Fl_Scroll::yposition() const

+ Gets the current vertical scrolling position. + +

void Fl_Scroll::position(int w, int h) +

+ Sets the upper-lefthand corner of the scrolling region. + + -- cgit v1.3.1
