[SOLVED] A widget update question

Hi , I am trying to update some widget by load some infortmation using self define function.

But the program crash every time when I set some attribute of the widget I want to update.

For example , here's my code:

class MyOwnGUI : public Ogre::FrameListener, public OIS::MouseListener
{
public:
MyOwnGUI()
{
enemyInfo = mGUI->createWidget<MyGUI::Progress>("Progress", 200 , 0 , 300, 22, MyGUI::ALIGN_TOP ,"Main");
enemyInfo->setEnabled(true);
enemyInfo->setProgressRange(100);
enemyInfo->setProgressPosition(100);

button = mGUI->createWidget<MyGUI::Button>("Button", 10,10, 300, 80, MyGUI::Align::Bottom, "Main");
button->eventMouseButtonClick = MyGUI::delegates::newDelegate(this,&MyOwnGUI::exit);
}
void updateInfo(Monster *m)
{
enemyInfo->setProgressPosition(m->getHP());
}

void MyOwnGUI::exit(MyGUI::WidgetPtr _widget)
{
button->hide();
}

private:
MyGUI::ProgressPtr enemyInfo;
MyGUI::ButtonPtr button;
};


Also , I tried to update the "enemyInfo" in exit function, and won't be crash .

So I am thinking maybe it's happened because I did't register the function , or losing something like widget as the parameter with the function...?

If it doen , can you guys teach me how to do that?

Don't know how to set/register the widget update function by some self define parameter like the example above ( Monster *m ).

Stuck for more than one day , maybe it's a newbie question.

But I really don't know how to figure it out.

Plz give me some advice. Thx for reading.

Thx for reply .

Still . I try to update the ProgressBar at last and crash.

But log seems no record that?

Can anyone give some advice 0.0??

Or some other ways to update widget in self define function with own parameter

Any help ~~ ?

All your code looks correct. Check that you use correct input parameters (for example check that Monster *m is not null). Also debug your program and find where you have crash.

I found it !!!

Sorry , I am a idlot >"<

I just check the Monster *m is not null , and create the receive GUI function at the monster class.

But forget to call the receiveGUI function to initial the gui at monster class.

So all the widget are null at the class.

At first I think it's because my function's parameter cause the crash.

But turns our is modified the null widget cause the crash.

Sorry

And thanks Altren , and my.name ^^.
