How do I get rid of this anonymous draggable bar in qtcreator?
<p>I wrote a program in qt creator, but it includes this anonymous draggable toolbar that I would like to get rid of. It does not show up in design mode. If I right click on it, it gives me a menu with a checkbox, which I can select to get rid of it while the program is running. What is this bar? How do I get rid of it? If I knew what it was, I could just programmatically tell it to hide when the program loads.</p>

<p>Here are some screenshots demonstrating this weird problem. In the first screenshot, the mouse is pointed at the bar. The second one demonstrates the right-click context menu. The third one shows the program without the bar. The box can also be dragged out of the program's window entirely. I can also upload a picture of that, if necessary.</p>
