Textbox mit SFML führt immer zu std::bad_alloc

[MrBambi]

Hallo zusammen, ich wollte in SFML eine Textbox erstellen. Die Klasse sieht so aus:

#include "Textbox.hpp"

	Textbox::Textbox(std::string id, sf::Vector2f position ,sf::Vector2f size ,std::string defaultstring)
	{
		setID(id);
		mPosition = position;
		mSize     = size;
		setBlocked(false);
		mText.setString(defaultstring);
		mText.setCharacterSize(size.y-8);
		mIsActive = false;
		setClicked(false);

		createGraphic();
	}

	void Textbox::reset()
	{
	}

	void Textbox::createGraphic()
	{
		quads = sf::VertexArray(sf::Quads,5);
		lines = sf::VertexArray(sf::LinesStrip,5);

		quads[0].position = sf::Vector2f(mPosition.x , mPosition.y);
		quads[1].position = sf::Vector2f(mPosition.x + mSize.x,      mPosition.y);
		quads[2].position = sf::Vector2f(mPosition.x + mSize.x,      mPosition.y + mSize.y);
		quads[3].position = sf::Vector2f(mPosition.x , mPosition.y + mSize.y);
		quads[4].position = sf::Vector2f(mPosition.x , mPosition.y);

		quads[0].color = sf::Color(255,255,255,255);
		quads[1].color = sf::Color(255,255,255,255);
		quads[2].color = sf::Color(255,255,255,255);
		quads[3].color = sf::Color(255,255,255,255);
		quads[4].color = sf::Color(255,255,255,255);

		lines[0].position = sf::Vector2f(mPosition.x , mPosition.y);
		lines[1].position = sf::Vector2f(mPosition.x + mSize.x,      mPosition.y);
		lines[2].position = sf::Vector2f(mPosition.x + mSize.x,      mPosition.y + mSize.y);
		lines[3].position = sf::Vector2f(mPosition.x , mPosition.y + mSize.y);
		lines[4].position = sf::Vector2f(mPosition.x , mPosition.y);

		lines[0].color = sf::Color(0,0,0,255);
		lines[1].color = sf::Color(0,0,0,255);
		lines[2].color = sf::Color(0,0,0,255);
		lines[3].color = sf::Color(0,0,0,255);
		lines[4].color = sf::Color(0,0,0,255);

		mText.setColor(sf::Color(87,158,56));
		TextboxRect = sf::IntRect(mPosition.x,mPosition.y,mSize.x,mSize.y);
	}

	void Textbox::update(sf::Event *e, sf::RenderWindow *rw)
	{
		updateText();
		checkMouseToBox(e,rw);
	}

	void Textbox::draw(sf::RenderWindow *rw)
	{
		rw->draw(quads);
		rw->draw(lines);
		rw->draw(mText);
	}

	void Textbox::checkMouseToBox(sf::Event *e,sf::RenderWindow *rw)
	{

		if(TextboxRect.contains(static_cast<sf::Vector2i>(sf::Mouse::getPosition(*rw))))
		{
			if(mIsActive == false)
			{
				if(sf::Mouse::isButtonPressed(sf::Mouse::Button::Left))
				{
					if(sf::Event::MouseButtonReleased)
					{
							mIsActive = true; 
							mText.setString("");
					}
				}
			}
		}
	}

	void Textbox::checkEnterdText(sf::Event *e,sf::RenderWindow *rw)
	{
		if(mIsActive == true)
		{
			for (int i = 0; i < 5; ++i)
			{
				quads[i].color = sf::Color(212,212,212);
			}
			mText.setColor(sf::Color(198,28,28));

			if(e->type == e->TextEntered)
			{
				std::string name = ""; 
				if (e->text.unicode < 128)
				{
					if(e->text.unicode != 13)
					{
						 name += static_cast<char>(e->text.unicode);
						 mText.setString(mText.getString()+name);
					}
				}

				if(mText.getLocalBounds().width > Textbox::mSize.x)
				{
					std::string t;
					t = mText.getString();
					t.resize(t.size()-1);
					mText.setString("");
					mText.setString(t);
				}

			}

			if (sf::Keyboard::isKeyPressed(sf::Keyboard::BackSpace))
			{	
				std::string temp;
				temp = mText.getString();
				if(temp.size() >= 1)
				{
					temp.resize(temp.size()-1);
					mText.setString(temp);
				}
			}
		}
		else
		{
			mText.setColor(sf::Color(87,158,56));
			for (int i = 0; i < 5; ++i)
			{
				quads[i].color = sf::Color(255,255,255);
			}
		}

		    if (sf::Keyboard::isKeyPressed(sf::Keyboard::Return))
			{	
				mIsActive = false;
			}
	}

	void Textbox::updateText()
	{
		mText.setPosition(mPosition.x,mPosition.y+mSize.y/2-mText.getCharacterSize()/2-5);
	}

	void Textbox::handle(sf::Event *e,sf::RenderWindow *rw)
	{
		checkEnterdText(e,rw);
	}

	void Textbox::setPosition(sf::Vector2f position)
	{
		mPosition = position;
		createGraphic();
	}

Wenn ich sie nun in einer anderen Datei aufrufen möchte:

Textbox *t = new Textbox(...);

bekomme ich immer einen Fehler names "C++ exception: std::bad_alloc". Weis jemand evtl. woran das liegt?

was sagt der Debugger ?

if(mText.getLocalBounds().width > Textbox::mSize.x) 
                 { 
                     std::string t; 
                     t = mText.getString(); 
                     t.resize(t.size()-1);  // <---------------- nix globb!
                     mText.setString(""); 
                     mText.setString(t); 
                 }
