fltk.customwidget

Base class for creating custom widgets.

CustomWidget allows you to create widgets with custom drawing and event handling by setting the onDraw and onHandle delegates.

The onDraw delegate is called when the widget needs to redraw itself. Use the fltk.draw module functions to draw the widget content.

The onHandle delegate is called when the widget receives an event. Return true if the event was handled, false otherwise.

Example:

import fltk.customwidget;
import fltk.draw;

auto widget = new CustomWidget(10, 10, 100, 100, "Custom");

widget.onDraw = () {
   // Draw a filled rectangle
   setColor(Color.RED);
   fillRect(widget.x, widget.y, widget.width, widget.height);
};

widget.onHandle = (int event) {
   if (event == Event.PUSH) {
      writeln("Mouse clicked!");
      return true;
   }
   return false;
};
