Check box usage method

[estamisu]

Hello ALL

Actually I am using Irrlicht I made checkboxes in my game. So I want to do another process when one of the checkboxes is checked. I can not handle it... Is there anyone help me

do you mean a new thread? no multithreading with irrlicht.

If all graphics rendering stays within the main thread, there's no problem with having multi-threading with Irrlicht. So just use the thread API you like and spawn the threads at the proper place. Probably in the event receiver. You need to take care of the thread joining somewhere else, in order to delete them for sure in the end.

hI THANKS FOR YOUR REPLIES BUT I CAN NOT DO IT TILL .

THIS IS MY CODE. SO CAN YOU SUGGEST SOMETHING TO DO:
WHAT I WANT TO IS THAT "WHEN FIRST CHECKBOX IS CHECKED SHOW THE BUTTON WHICH IS "YES THAT'S RIGHT"



}

Code: Select all

if (event.EventType==irr::EET_GUI_EVENT)
		{
			s32 id = event.GUIEvent.Caller->getID();
			IGUIEnvironment* guienv=device->getGUIEnvironment();

		switch(event.GUIEvent.EventType)
		{

			case EGET_BUTTON_CLICKED:
			{
									
					IGUICheckBox* chk = (IGUICheckBox*)guienv->getRootGUIElement()->getElementFromId(MYGUI_BOLD,true);// enen deer ochood button press hiigdeh yum baina
					bool bold = true;//chk->isChecked();
					if(bold)
					{
					ch = (IGUIButton*)guienv->getRootGUIElement()->getElementFromId(MYGUI_HELPBUTTON,true);
					}
					
					IGUICheckBox* chk1 = (IGUICheckBox*)guienv->getRootGUIElement()->getElementFromId(MYGUI_ITALIC,true);
					bool italic = chk1->isChecked();

					IGUICheckBox* chk2 = (IGUICheckBox*)guienv->getRootGUIElement()->getElementFromId(MYGUI_ALPHA,true);
					bool alpha = chk2->isChecked();

					IGUICheckBox* chk3 = (IGUICheckBox*)guienv->getRootGUIElement()->getElementFromId(MYGUI_ANTIALIAS,true);
					bool aa = chk3->isChecked();

					// vector fonts disabled
					//chk = (IGUICheckBox*)env->getRootGUIElement()->getElementFromId(MYGUI_VECTOR,true);
				//bool vec = false;//chk->isChecked()
			}

			case EGET_CHECKBOX_CHANGED:
			
			if(id==MYGUI_BOLD)
			{
			//{		
			//IGUICheckBox* chk = 0;

				IGUICheckBox* ch = (IGUICheckBox*)event.GUIEvent.Caller;

			//if(bold)
			//{
			//	
			//		ch = (IGUIButton*)guienv->getRootGUIElement()->getElementFromId(MYGUI_HELPBUTTON,true);

			}	
			

				}

...


guienv->addGUIElement("GUIEditor");


			IGUIWindow *win =guienv->addWindow(core::rect<s32>(10,10,260,220), true, L"Good Luck for your Test",0, -1);
			win->getCloseButton()->setVisible(false);
			IGUISkin *skin = guienv->createSkin(EGST_WINDOWS_CLASSIC);
			guienv->setSkin(skin);

			//if(guienv)
			//{
			guienv->addButton(core::rect<s32>(35,35,200,50), 0, 0, L"Please choose right word" );
				
				//guienv->addCheckBox(true, rect<s32>(35,35,80,100), 0,0, L"Star");

			s32 xs=10,xp=xs, yp=50, h=20;
				// bold checkbox
			guienv->addCheckBox(false, core::rect<s32>(xp,yp,xp+60,yp+yp),win, MYGUI_BOLD, L"sar");

			xp += 45;

			// italic checkbox
			guienv->addCheckBox(false, core::rect<s32>(xp,yp,xp+80,yp+yp),win, MYGUI_ITALIC, L"nar");

			xp += 45;

			// AA checkbox
			guienv->addCheckBox(false, core::rect<s32>(xp,yp,xp+80,yp+yp),win, MYGUI_ANTIALIAS, L"mangar");

			xp +=40;

			// Alpha checkbox
			guienv->addCheckBox(false, core::rect<s32>(xp,yp,xp+80,yp+yp),win, MYGUI_ALPHA, L"teneg");

			xp = xs;
			yp += (s32)(h*1.5f);
			
				device->getCursorControl()->setVisible(true);

				device->sleep(5, true);

		}
			if(ch)
			{
			guienv->addButton(core::rect<s32>

(35,35,200,50), 0, 0, L"Yes That's right" );
			}
			//win->setVisible(false);

well, what should this be about :

Code: Select all

switch(event.GUIEvent.EventType)
  case GUI_ID_CHECKBOX_VISIBLE:
     for ( u32 i=0; i < mGuiElements.size(); ++i )
    {
      mGuiElements[i]->setVisible( cb->isChecked() );
    }
    break;
  case GUI_ID_CHECKBOX_ENABLED:
    for ( u32 i=0; i < mGuiElements.size(); ++i )
    {
      mGuiElements[i]->setEnabled( cb->isChecked() );
    }
    break;
} 

GUI_ID_CHECKBOX_VISIBLE and GUI_ID_CHECKBOX_ENABLED are not related to event.GUIEvent.EventType in any way !!!
where do you set GUI_ID_CHECKBOX_VISIBLE or GUI_ID_CHECKBOX_ENABLED for the event type !?!?!
