Re: [paragui-users] Bug in WidgetList

Hi Alex,

I can only provide a demonstration at the moment. I've try it with 1.0.3 and 
1.0.4beta. I hope it helps to understand the problem.

(Cause of the missing update of PG_Application the hide of the WidgetList is 
not to seen on the screen. But there is a Debug Message).

Source:

#include <pgapplication.h>
#include <pgbutton.h>
#include <pgwidgetlist.h>

PARAGUI_CALLBACK(exit_handler) {
    PG_Application* app = (PG_Application*) clientdata;
    app->Quit();
    return true;
}

PARAGUI_CALLBACK(show_handler) {
    PG_WidgetList* list = (PG_WidgetList*) clientdata;
    list->SetVisible(true);
    list->Update();
    std::cerr << "Hide" << std::endl;
    return true;
}

PARAGUI_CALLBACK(hide_handler) {
    PG_WidgetList* list = (PG_WidgetList*) clientdata;
    list->SetVisible(false);
    list->Update();
    std::cerr << "Hide" << std::endl;
    return true;
}


int main(int argc, char* argv[]) {
    PG_Application app;
    app.LoadTheme("default");
    app.InitScreen(640, 480, 16, SDL_SWSURFACE);

    PG_Button myButton(NULL,1,PG_Rect(260, 100, 120, 50),"Exit!");
    myButton.SetEventCallback(MSG_BUTTONCLICK, exit_handler, &app);
    myButton.Show();

    PG_WidgetList list(NULL,PG_Rect(10,10,150,150));
    list.EnableScrollBar(true, PG_SB_VERTICAL);
    list.SetTransparency(0);
    list.Show();

    PG_Button myButtonHide(NULL,1,PG_Rect(260, 0, 120, 50),"Hide!");
    myButtonHide.SetEventCallback(MSG_BUTTONCLICK, hide_handler, &list);
    myButtonHide.Show();

    PG_Button myButtonShow(NULL,1,PG_Rect(260, 50, 120, 50),"Show!");
    myButtonShow.SetEventCallback(MSG_BUTTONCLICK, show_handler, &list);
    myButtonShow.Show();

    app.Run();
    return 0;
}


Compile Option:

g++ -I/usr/include/paragui -I/usr/include/SDL -I/usr/include/freetype2 
-L/usr/lib -lparagui -lSDL -lfreetype WidgetListBug.cpp
