I have a similar question as asked in How to know if QListWidgetItem is hidden by scroll? and the answer to that question didn't fix my problem.
Basically I have a QScrollArea having QGridLayout. This layout has many QToolButtons. Based on some condition, all these QToolButtons need to be updated. To update all of them always is not so efficient, so I want to update only the buttons which are visible in the current active window. How can I achieve this? isVisible() doesn't help here.
Thanks in advance!
You can use QWidget::visibleRegion() to check whether widget is visible and paint events can occur for widget.
if (!button->visibleRegion().isEmpty())
{
//button is visible
}
I've got div with overflow="scroll" on it, which is displaying content (icefaces app). I've got event for right mouse button with displaying context menu of element of this content, but context menu is displaying inside of this div, i must scroll to see this context menu. This context menu is hidden div - after mouse click it's set to visible.
It's physically putted inside of scroll panel (and it unfortunatelly must be inside). Anyone have idea how to resolve this problem (i tried everything from google). Maybe some js trick or something like that? ;)
Problem is that i need it out of this scroll ;)
Thanks a lot.

As per screen :
you can see that as soon as numberpad popping up. its overlapping the some text field, I have in the app. moreover its not having have done or return button so that I can make numpad go away. I have made button to make keyboard go away but I want some more professional way.
please suggest. how can I add return or done button with keyboard and if there is another possible way I can reduce the size of keyboard.
As far as i know it is not possible to make the keybord smaller but what you can do is make your view move up once you have tapped on a UITextField this code will help you with that
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.25];
self.view.frame = CGRectMake(0,-10,320,400);
[UIView commitAnimations];
}
Now to the next issue u have to dismiss the keyboard I like to make it so that the user can just tap the background and it will resign the first responder. You can do that like this
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
In dismissKeyboard
-(void)dismissKeyboard
{
[aTextField resignFirstResponder];
}
Hope this helps

When I click on any filter and then I click to "all" filter, the content moves a little bit to the left. Why?
Because your scrollbar is appearing.
I think vertical scroll bar display when clicked on the all filter. that's problem.
I've got an Horizontal List. It contains 6 XML Nodes at the moment. But what I'd like to do is remove the scrollbar so that an button can function to scroll through the nodes instead.
Has anyone achieved this, if so how did you go about it?
Thanks in advance
You can usually remove the scroll bar by setting the horizontalScrollPolicy or verticalScrollPolicy to off.
After that, I believe you can scroll the list by setting the verticalScrollPosition or horizontalScrollPosition
