When I open a page of my application in the browser, I can see the debug toolbar at the bottom of the page. When I click on the timeline, however, the data is shown in a canvas.
I'm blind, and thus can't interact with a canvas through my screen reader. I'm wondering if there's a way to view the timeline data, without having it drawn on a canvas?

I have a popup in my app which can be moved by the user to another screen. The popup is show in intervals. When the user unplug or turn off the screen and the popup is shown, actually it is not, because the screen is off. How to detect when the popup (Qt quick Window type widget) is really visible for the user?
So the console preview panel at the bottom of the page remembers how big you had it last time you previewed. Usually this is great! But somehow mine is currently maximized, so the only thing that shows up is the Page dropdown at the top of the page (and anything in the console, if I switch between pages and the pages have things that log on load). The rest is just white console. Any idea how to get back the default view where the console is 20% of the bottom of the page? There is no visible dragging bar frame thing anywhere.
I can change my preview to console=0 to be able to use it, but I'd like a way to restore the default position of the panel.
Normally you should be able to hover on the top border of the console panel and resize it as you wish. An icon will appear, similar as in the image below:
Nonetheless, if you are doing your previews on a mobile device such as a tablet, then such thing is not possible to do. Therefore; a hacky way to do it would be to put the following code on the onAttach event handler of the page that is loading:
var splitPanel = widget.root.getElement().parentElement
.parentElement.parentElement.parentElement
.parentElement.parentElement.children[0].children[3];
splitPanel.style.height = "75px";
Nota bene: this is intended to ONLY work in preview
I am working on a Touchscreen application.
For this I Need to Change the current window if user clicks on the Screen (Position doesn't matter).
For this I Need a to make my button (which is currently the same size as the current window) invisble, so user can see the Labels etc.
Any idea how to make Buttons invisible in PyQt4?
I recommend you not use a button to do this. Instead, either put an event filter on the QApplication instance, so any widgets in your window get events only if you determine they should; OR put a transparent panel widget over the touch area, with a mouse click event handler for that panel. Either method supports arbitrary complexity of widgets inside your touch area (labels and tables to display information etc). Main disadvantage with event filter approach is that all application events (from all threads) will be filtered. This could affect performance (you'd have to test, may not be any noticeable differenc), but it is simpler to implement than the transparent panel.
When in landscape mode, the UISplitViewController displays the detail and master views.
The detail view has an AdBanner in it. However, when we set the AdBanner's CurrentContentSizeIdentifier to SizeIdentifierLandscape the banner is too wide for the detail view.
How can we put AdBanners in the Detail view of a UISplitViewController?
If a banner with ADBannerContentSizeIdentifierPortrait fits, you could use that.
Or you could put the ad banner view on top of the UISplitViewController's view in the UIWindow and construct your sub-controllers in such a way that it looks right with the ad banner overlapped, although that may give you other problems when it comes to orientation updates.
Or you could try adding the ad banner as a subview of the UISplitViewController's view, and possibly also adjust the positions of its other subviews to try to get things to not overlap, but this may or may not be allowed if you want your app approved for the app store.
Otherwise you're just out of luck.
I have two overlapping images. I touch the topmost image and start moving (touchmove) finger around. All subsequent touchmove events are received by that image. In the middle of this interaction I want the events to go to the image underneath, so that I can move it around instead.
How to change the event source to the image underneath? That is, once an object has started receiving touch events, how do I change the target of those events?
I suspect that Joe Blow is talking about handling touch events in the context of a native iPhone app built with Objective-C.
Eric's question is about handling touch events in Mobile Safari with JavaScript.
I could be confused though...
