how to implement a gui in cpp code?

[Charrua]

I started another thread (https://www.leadwerks.com/community/topic/16553-handling-widgets-created-cpp-side-and-lua-side/) because i started with a gui in lua and then has the need to create and handle some widgets in cpp code, i had some troubles and guessed that the problem was in a bad parameter usage/passage.

So I decided to make it work only in cpp code and i found that the test (event->source == butt1) never gets true, the same problem that i have when calling a method from lua passing the event peeked from the queue.

Relevant parts of my code:

/* globals */
GUI* gui;
Widget* butt1;

 

/* in App::Start */
gui = Leadwerks::GUI::Create(context);
butt1->Button("Quit",30,30,100,50,gui->GetBase());

/* function to process events */
bool App::ProcessEvent(Event* event){

    if (event->id == Event::WidgetAction) {
        System::Print("widget action!");
        if (event->source == butt1) {
            System::Print("butt1 pressed");
            butt1->Hide();
            return false;   //quit
        }
    }
    return true;
}

 

inside App::Loop

    while (EventQueue::Peek()){
        System::Print("event queue peek");
        Event event = EventQueue::Wait();
        if (ProcessEvent(&event)==false) return false;
    }

what am I doing wrong?

thanks in advance

at a first glanse i would say.

This:

butt1->Button("Quit",30,30,100,50,gui->GetBase());

Should be this:

butt1 = Widget::Button("Quit",30,30,100,50,gui->GetBase());

Also i advice to always add a panel script to your gui when you create one.
This neutralizes certain problems you could come across.

	gui = GUI::Create(context);
	gui->GetBase()->SetScript("Scripts/GUI/Panel.lua");
	gui->GetBase()->SetObject("background", new Vec4(0,0,0,0));

while (EventQueue::Peek())
{
	auto event = EventQueue::Wait();
	if (event.id == Event::WidgetAction)
	{
		if (event.source == button) {

I have this in main loop keeping things simple.

Worse case use debugger to see what is happening in ProcessEvent.

thank's

I test the panel thing as GrozenDev suggested and works! but.. always a but i found other problem, not related with the gui itself.., it's related to latest beta, visual studio 2017.. don't know exactly ... will see

Thanks i found my error 

it was 

Leadwerks::Widget::Button("", (this->window->GetWidth() / 2) + 100, 250, 100, 55, panel);

TO

Leadwerks::Widget::Button("", (this->window->GetWidth() / 2) + 100, 250, 100, 55, gui->GetBase());
