Detailed Description

A valuator that displays the number like a text box. This is indended for showing the user a number, there is no way for the user to change the number. It is much lighter weight than using an Output widget for this.

There is no way for the user to change the number, but calling value() will change it.

Member Function Documentation

void ValueOutput::draw ( void  ) [virtual]

Fltk calls this virtual function to draw the widget, after setting up the graphics (current window, xy translation, etc) so that any drawing functions will go into this widget.

User code should not call this! You probably want to call redraw().

The default version calls draw_box() and draw_label(), thus drawing the box() to fill the widget and putting the label() and image() inside it to fill it, unless the align() flags are set to put it outside.

Information on how to write your own version is here.

Reimplemented from fltk::Widget.

int ValueOutput::handle ( int  event) [virtual]

The base class handle() accepts FOCUS and recognizes a number of keystrokes that adjust the value. A subclass can call this to get these keystrokes, it can also do it's own keystroke handling if it wants.

Reimplemented from fltk::Valuator.
