Hi Rahul,

          Firstly, you want a border around the Desktop Screen is
          Secondly, you need a widget at top left corner of screen which has some buttons and shouldnt move around or should be cooupled with the 1st widget.

I would like to keep my design as 2 separate widgets one for just drawing the borders around screen or in future around other applications on desktop and 2nd widget as a title bar as this will allow code modularity but at a lil work from your side.

Some of questions I have are: is title bar movable ? can it move separately and if it can move should the whole paint border move ? In that case you need to override the mousePressEvent and mouseMoveEvent.

If title bar is immovable then it should be pretty simple to implement.

Also, if you want you can keep the 2 widgets as part of a parent widget which will be transparent to mouse events as well.

Let me know if you have any concerns or misunderstood the question.

-Raja.

Hello Raja/ Stefano,

UI Requirement has been modified as mentioned in picture above.
I have posited a question on list but did not got any kind of answer, so I am addressing the problem .

Using this call setAttribute(Qt::WA_TransparentForMouseEvents); makes title bar buttons useless, I fact now we need some portion to accept mouse events and rest don't.

Next challenge is to create a Title bar, as shown above in figure.

Title bar is actually very small and widget is of the size of desktop. Plus there is only one button for close and no other buttons for minimize and maximize.
Apart from it, widget also has some area which is not transparent to mouse events and is visible, where I can have buttons.

Any suggestions and help would be highly appreciated.

Thanks,
Rahul

create a QWidget and get screen geometry using QDesktopWidget.

Set this flags:

setAttribute(Qt::WA_TranslucentBackground);

setAttribute(Qt::WA_TransparentForMouseEvents);
and if you want to draw a border jus override the paint events and create a QPainter object in it and just paint the border.

Take a look to QWidget::setMask to create a widget with "holes" and QDesktopWidget to get desktop geometry.

Hello All,

I am creating a widget which has following requirements.

1. Widget covers an entire screen. Like full screen.

2. Thick blue border.

3. Widget is such that I can see UI in the background. .i.e. I can see my desktop.

To summarize this, it's like putting a border on your desktop. One can also consider it as creating a Frame for a desktop.

Any help is highly appreciated.

Thanks

Rahul
