I have a popover which contains a tableview, once a row has been selected I want to then push on a UIImagePickerController.
According to the documents on the Apple website, I can only present this in a new view controller. How do I present a popover, in a popover? Or is there another way to do it?
The easiest way is to create a delegate and dismiss the tableview on didSelectRowAtIndex using either an exit unWind segue or by dismissing the popover manually using a delegate. Then present the popOver containing the UIImagePickerController. You could also just use the delegate to display a popover along with the tableview although that probably would look cluttered.

Is it possible to detect selected row index with force touch? Did force touch in tableView current row is highlighted. But i can't take info about him when context menu appears. TableView method -didSelectRowAtIndex: not called with this event.
The only thing you can handle programmatically with the Force Touch is the Context Menu and this menu is associated with a specific controller, more information you will find following the link.
About the row highlighting: When you start tapping the system doesn't know what the real action is - the regular touch or the force one. So it is starting to highlight a specific area and only later find out what was the action.
So i have a static tableview with 4 rows, i'm connecting them to different viewcontrollers without using any code instead i'm simply dragging the cell and setting up the segue.
The issue i'm having is that when this segue is performed a navigation controller is automatically generated and embed at the top so i get the following result below.
How could i edit the text and the icon? I want to remove the settings text and use my own custom icon.
It's also worth noting that i have embed other navigation controllers throughout my app. So i'd like to target this view specifically rather than all of my views.
I suspect the accepted answer on this question may help: how to replace/customize back button image in storyboard navigationcontroller
You'll need to do it in your prepareForSegue I believe.
I got a QGraphicsScene that contains QGraphicsItems. On clicking such an item I open a dialog. I now want the item to be displayed in an area of the dialog.
I tried a QGraphicsView (in the dialog) and "pointed" it to the item which works allmost perfectly. The problem is, that it is possible to click the item in the dialog which would open a new dialog.
So my question: is there a easy way to tell QGraphicsView to ignore any input events? If not, is there a easy way to display a QGraphicsItem within a widget?
I am feeling so stupid...
QGraphicsView::setInteractive(false) did the trick.
I am still able to move the icon with the mouse wheel but this can probably be avoided by restricting the scene rect with setSceneRect()
You can install an event filter, on the QGraphicsView, which ignores input events. The Qt documentation states:
In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
I am programming in C++ in QT and trying to make a UI with dynamic tabs having tables inside each of them. For doing the same, I had my TabWidget in the main window, and another widget with just the tableView. As the tabs are dynamically being added to the main window by a button click, I make a new object of my widget and put it in that.
I also have another version of the application in which there are no tabs, just a tableView in the main window.
I am unable to open the context menu in the former case, while it works perfectly for the latter.
I am using the signal "customContextMenuRequested" in both the cases. Don't understand what I need to add for it to work when the tableView is in a child widget.
Some help please?
Thanks already!
Did you check that nothing is involving QAbstractScrollArea, it's possible that in this case it would signal/slot as expected.
This signal is emitted when the widget's contextMenuPolicy is Qt::CustomContextMenu, and the user has requested a context menu on the widget. The position pos is the position of the context menu event that the widget receives. Normally this is in widget coordinates. The exception to this rule is QAbstractScrollArea and its subclasses that map the context menu event to coordinates of the viewport() .
I have the navigationcontroller based viewcontroller and I overriding the root view controller navigation bar back button in to my custom segment control with different purpose. This navigation controller is placed one of the separate tab in the uitabbarcontroller. If this is used as the separate tab bar then no problem.
But if i use this navigationcontroller inside the more option in tabbarcontroller i am not able to come back to the more option list because of backbutton is overridden in my navigationcontroller.
My idea is add one back button only if my navigationcontroller is used more option tab otherwise i need to hidden the back button.
Please help me in this issue?
You can check if a view controller is in the 'more' section as follows:
BOOL isOnMoreNavigationController = [tabBarController.moreNavigationController.viewControllers containsObject:myViewController.navigationController];
From a UI consistency perspective it might be better to always show the back button in its standard position and move your custom buttons to some other place.
