Question

I’m having an issue. My textEditBox doesn’t seem to be updating when my Addtext function is called.

Here’s my Addtext:

void CTextBox::AddText(QString string, QString spriteString)  
{

    textBrowser->setText(string + spriteString);
    update();

}

Another class then calls the function and it should add text to the textbox but it doesn’t.

How do you call CTextBox::AddText()? update() only schedules a paintEvent() for later, when the program returns to the event loop. That means that

1. you actually need to have an event loop, ie. at some point you need to call qApp->exec();

2. you need to allow the programm some time to qApp->processEvents() (insert that after update()), if you want any paining done within a blocking while() {...} or something like that.

Edit: Come to think of it, you shouldn’t even need to call update() nor processEvents() if your program returns to the event loop some time after AddText, so there really seems to be an issue with the event loop. Post your main.cpp, will you?
