Update (recreate?) Edit widget without changing scroll pos

I want to highlight on mouse over my talking dialogue response options. This is the code that (almost) works, but there is a problem if the text is larger than the edit widget. The recreated text gets scrolled.

I'd like to save the current scroll position before i clean the edit widget, and restore it after recreating.

void DialogueGui::PrintResponsesForDialogue( Dialogue* dialogue, int x, int y , bool refresh /*= false*/ )

{

	size_t scroll;

	if(refresh)

		scroll = mResponsesGui->getScrollPage();  //this does not work due to the fact it's private

	else

		scroll = 0;



	int i=0;

	mResponses.clear();

	MyGUI::IntPoint point;

	point.top = y - mResponsesGui->getAbsoluteTop();

	mResponsesGui->eraseText(0,mResponsesGui->getTextLength());

	

	for(std::vector<Ogre::String>::iterator it = dialogue->getResponses().begin(); it!= dialogue->getResponses().end(); it++)

	{

		DialogueResponse *response = DialogueManager::getSingleton()->getResponse(*it);

		if(response->areRequirementsFulfilled())

		{

			responseRegion rr;

			rr.coord = mResponsesGui->getTextSize().height - mResponsesGui->getFontHeight(); 

			rr.response = response;

			mResponses.push_back(rr);



			Ogre::UTFString color;

			if(point.top > rr.coord && point.top < rr.coord + mResponsesGui->getFontHeight())

				color = L"#CC4433";

			else color = L"#FFFFFF";

			const Ogre::UTFString& currentDisplay = StringManager::getSingleton()->get(response->getTextID());



			mResponsesGui->addText(color + currentDisplay);



			std::wcout << rr.coord << currentDisplay.asUTF8_c_str() << std::endl;

			mResponsesGui->addText(L"\n");

		}

		++i;

	}

	mResponsesGui->notifyScrollChangePosition(0,scroll);   //this does not work due to the fact it's private

}

Sorry for the a bit messy code.

What for ? I'd need to show a movie. As I add text which size exceeds the size of the edit widget the text gets scrolled down to show the last line. As I recreate the text in a eventMouseMove it is not possible to click the first line. Even if i'd lock scrolling on adding text it wouldn't be the desired effect, because then I would not be able to click the last text line. I need to save the current scroll position before recreating the text, and restore the scroll position afterwards.

The list with multilower case lines is necessary to you?

Something like this, yes, but I handle it myself using a simple Edit widget. All I really need is to get the current Edit widget scroll position, and scroll the text from code.

Leave it for now. Functionality that you need will be implemented soon.
