A basic GUI lib for Skia based projects. The only base layer for this GUI is currently SDL.
A SKiaGui program creates an SDLSkiaApp instance. This app object handles the event loop.
Create a SDLSkiaWindow and hand it a WindowClient, which handles the window's events.
A typical main.cpp looks like this
int main(int argc, char** argv) {
SDLSkiaApp app;
auto wndClient = GraffelWindowClient();
if (app.createWindow("My App", (int)(app.dm.w * 0.7), (int)(app.dm.h * 0.7), wndClient, 0))
app.startEventLoop();
return 0;
}
A WindowClient is used to interact with the actual window. A basic WindowClient would simply add visual components to the window.
class MyWindowClient : public WindowClient
{
private:
SplittableArea mainView;
UIElement toolbar;
UIElement *button1;
...
public:
void initialize() override; //create the mainView and other visual components and setup the hierarchy.
SplittableArea* getMainView() override { return &mainView; } //only required override. The Window must know the top of the visual's hierarchy.
initialize(); //note that these are NOT virtual functions
onIdle();
//not that an absolute minimum of events is implemented in the ClientWindow interface. Most event handling happens in the visual components.
