To create a custum widget, this is as simple as complex.
|
|
The first things to do is to choice a methode to display you widget:
|
|
:** [b]Direct mode:[/b] display on openGL engine with your prefered methode (some help for shaders)
|
|
:** [b]Compositing:[/b] display with a toolbox for drawing on openGL
|
|
:** [b]Shaper:[/b] this is a special mode of compositing
|
|
:** [b]Add capacity:[/b] this could be interesting to increase some capacity of a widget...

#include <ewol/widget/Widget.h>

namespace appl {
|
|
class myWidget : public ewol::Widget {
|
|
public:
|
|
myWidget(void) {};
|
|
~myWidget(void) {};
|
|
public: // herited function
|
|
void draw(void);
|
|
void onRegenerateDisplay(void);

}

We can show that we had two function, the first is call every time we render the widget (as the number of fps) "draw()".
|
|
And the second that is call only when we need to redraw the widget (after the user call markToRedraw() ) "onRegenerateDisplay()".
