I'm trying to put two pictures in the QGraphicsScene. One is fixed and the other one is movable. But I succeed only in putting those pictures in the QGraphicsScene, I can't move them. How can I achieve this?
You have to make sure the item is movable. Have a look at QGraphicsItem::setFlag.
You'll have to do something like this :
myImageItem->setFlag(QGraphicsItem::ItemIsMovable, true);

like this, the lines alway cover my other widget. Althought I use Qt::WindowStaysOnTopHint to set other widget, it doesn't work.
how can I solve the problom?
First of all, I'm fairly new with Qt and Qt Creator so go easy if this is a stupid question.
I was practicing using Qt Creator, playing around with css styles. In particular, I'm trying to get the menubar and its menus to look something like this (on Windows): http://i.stack.imgur.com/9lMnQ.png.
However, the closest I've been able to get so far is this: http://i.stack.imgur.com/5Nlen.png.
I've searched online to see if anyone has tried something like this but I wasn't able to find anything.
The only possible solution I can think of is if the menubar item (with no bottom border) could be rendered in above the menu, so that they overlap, covering its top border over the width that they overlap.
If that won't work or is impossible or whatever please do suggest any other solutions/workarounds/hacks.
Thanks in advance!
I think that the only good solution is to avoid any tricks and create a new widget:
Create a new class inherited from QWidget with Qt::Popup attribute.
Place a QMenu into a layout of the widget.
Get a position of QMenuBar item which is clicked using QMenuBar::getActionGeometry.
Calculate position of the widget and of the tab in the widget to be placed over the menubar item.
Customize form of the widget using QWidget::setMask to make it look like a rectangle with a tab.
Show your widget instead of QMenu.
I want to make something like a hud. I have a QGraphicsScene with a huge QPixmap, that I added to a much smaller QGraphicsView. Now I need to add some control elements, like QLabel, QPushButton and QGraphicsEllipseItem. That's, I think, is not a problem. I found this helpful page Graphics View Classes. But how do I anchor this control elements to the View or maybe better said how do I not anchor them? When I drag the QPixmap, then I don't want that the hud is moving with the QPixmap out of the QGraphicsView.
What do I need to do, to solve this problem. Hope someone can help me.
You should just have to create your widgets and specify the QGraphicsView in the constructor like this:
QPushButton *button1 = new QPushButton(view);
i have a window in Qt, on that i am drawing a picture. now i want to place the progressbar over it.
how can i do that?..
steps i am following to do
Create a window,
Draw picture in paint event of window
Then create QGridLayout layout, add your window
Display over it.
suppose i want to add progress bar, over a portion of picture window. how can i do that
i dont think its possible to implement in window paint event.
please assist me
Thanks
You can add the progress bar as child of your QWidget without adding it in the layout. This will draw the QProgressBar into the QWidget. Since you are not using the layout you will have to manually manage the position of the QProgressBar.
I think that just adding a progress bar widget to your grid layout should work.
I have main window and in this window I have QListWidget. I want this list to be central widget in the main window and I know that I can do that by writing code like setCentralWidget(QWidget*) and it works (list is spread on the whole mainwindow) but this isn't reflected in designer when the list is still in this same position and has the same size. Is there any way to make it so the change is visible in designer as well as in the code?
Thank you.
In Designer, right click on an area of the form next to the QListWidget, then choose Layout->Layout Horizontally (or vertically, almost anything is acceptable).
I figured it out. In order to do so I had to choose grid layout for main window and sizePolicy for list as Prefered.
