I am writing a simple application with Python3, Gtk3 and Webkit2. One of the elements is a webview, but I want the webview to be transparent to the background set for the parent container - in this case a Gtk.Paned in a Gtk.Box where the GtK.Box can optionally have a background image set.
Most of the solutions I've found out there give you a webview that is transparent to the screen/desktop. Like this solution:
Is it possible to render web content over a clear background using WebKit?
This is not quite what I want. Is there any way to choose what webview is transparent to? Or another approach that produces the desired result?
Good question, but as far as I know it's not currently possible.

I'm trying to resolve for my self the issue stated in this post from 2011:
https://bugreports.qt.io/browse/QTBUG-19008
Using the stylesheet approach does not work however.
What I would like to do (regarding my own GUI project) is ensure that the images on any disabled QLabels appears the same as when those QLabels are enabled.
Any help in resolving this particular problem would be awesome. Thanks.
Ok. So disabling the GUI is a problem if you have custom graphics for all the widgets because mid-grey boxes appear everywhere. So what is the solution?
Ekhumoro has provided one solution but here is another:
If you are using Animated GIFs there is no problem - they won't turn mid-grey.
If you are using static images (PNGs) all you have to do is make sure the background is transparent so that only the visible image will turn mid-grey for the duration that those graphics are disabled.
This may not be elegant but it is a workaround that can be considered.
I was able to make a full screen blur with the depth of field post process which I want to use for the background both my pause menus and my in game HUD. The issue is that when I want to use it for my in game UI it needs to only be rendered under the HUD and not the entire screen. Is there any way the I can mask the post process to a UMG widget for simplicity?
The other solution that I thought of was to create a material and mask it off in the material. The problem is that PostProcessInput0 already has the blur applied and I can't use the SceneColor any more, so I don't have a way to get the original texture without the blur. Is there any way to do this?
Cheers.
Just started working with this awesome external but have a couple of questions.
When the control is evoked, is it always the top layer or can I have a background transparent image on top of it so I can frame the control nicely?
Also, my testing seems to read most Barcodes but when it comes down to reading Barcodes on hard drives, the control does not want to decode those.... Too dense of bar code pattern?
I am very impressed thus far with the ease of use of your externals. Makes we want to code more for mobile devices!
an overlaying transparent image is not possible, as far as i know.
but couldn´t you use
command mergZXingControlSetRect pLeft,pTop,pRight,pBottom
to define the rect of that scanner after creation
or
command mergZXingControlCreate pLeft,pTop,pRight,pBottom
to create the scanner control in the specified rect.
Set the rect smaller than the width and the height of the screen.
You could then use an underlying image, which is displayed outside of the scanner rect, to show the frame around scanner control. Did not test it myself, but i would assume that this should work.
Unfortunately the native controls in externals and the ones the engine provides are added as views on top of the LiveCode view. That means you can't intermingle LiveCode controls with them. One thing that some users have done is add a web view with a transparent background and a load a png image. If you create the barcode view first and the web view second then the web view will be on top.
I'm creating a custom camera UI using UIImagePickerController cameraOverlayView property. However, I'd like to keep some of the existing UI -- specifically the flash and camera selection buttons at the top.
My thought was that I'd keep showsCameraControls = YES set the cameraOverlayView to my custom UI and then use [picker.view bringSubviewToFront:overlayView] to make sure my controls on the bottom are sitting on top of the default controls.
Alas, this does not work. I've tried moving the overlay to the front of the view hierarchy in various places without luck. Is there any UIImagePickerController hackery that could achive this? It seems a shame not to be able to reuse at least some of the camera controls while still customizing the UI.
Further investigation it appears this is not possible. You either have to use all of the default cameara UI or none of it.
i want to have default text in a textfield which disappears when the textfield gets focus. similar to the google search box in firefox.
also with java me is it possible to set a background image for a display.
The answer of your second question is easy. Unless you use canvas, it is not possible.
AFAIK you cannot handle focus events on a textfield in J2ME so it is not possible.
