I would like to make the plugin "lowerthird" appear only when the video is paused.
I.E listen to the pause event, and display the text from lower third plugin...
Thanks!
Popcorn events activate based on the time. So you would have to make an event, hide it using CSS, then make it visible on pause.

Is it possible (e.g. by overwriting a prototype) to filter (enable/disable) events globally in KONVA?
use case:
I have an interactive app built with KONVA. At the beginning, I want to show a "demonstration" of the user interface: I'm displaying a moving second mouse cursor and fire events which are handled by the app to demonstrate possible interactions. All is working, but during the demonstration, the app should not listen to real mouse events, only to the simulated ones (having a special property set in event object).
For that use case, just set listening: false for your stage. It will disable ALL events on the stage and its children.
You can turn off events just for demonstration. As soon as it is done, you can turn mouse/touch/pointers events on with listening: true.
I use the TTaskbar component in my Delphi application to show the progress of the current operation in the TaskBar.
At the beginning it should show a "Indeterminate" progress (known as pbsMarquee in the context of a ProgressBar).
If I set the status the "indeterminate" animation is only display a single time. I expect it to animate all the time until I change the ProgressState:
tbTaskBar.ProgressState := TTaskBarProgressState.Indeterminate;
Any thing I am missing? What I need to do to dislay the animation all the time?
is there a way to disable multiclicks? By multiclicks I mean 3-or more clicks. I would like to have only singleClick or doubleClick. The third click should be always registered as singleClick (clicks=1). event.mouse.clicks should always be <= 2.
Another problem is the interval between clicks. If I click multiple times on the same spot between 1-2 seconds, it is always registered as a multiClick (event.mouse.clicks keeps rising). Only if I move the cursor a bit, clicks would lover to 1. How can I change this behavior so the interval between click and doubleClick will be around 1/4 second?
Solution is to have a separate thread which reads the SDL information, then do a debounce algorithm to remove the unwanted clicks. I did this for a touch screen, which is too sensitive. After filtering, you should get what you want. Then the filtered events you put in a queue (std::deque) which can be used for the real user interface to get events.
The open source project https://sourceforge.net/p/sdl2ui/wiki/Home/ has a class CdialogEvent which is may just what you need.
I have a web page which can be janky to scroll if certain styles are applied. My question is how can I systematically test the effect of individual styles. I don't want to just manually scroll down the page each time, I want to perform some replicable action so I can easily compare the effect of two different stylesheets. Is it possible to record and replay a sequence?
In Chrome you can try using:
console.timeline('description');
// your code
console.timelineEnd('description');
You'll get a deprecation warning, but it works to record a timeline.
OR
You could use The Intern http://theintern.io/ to automate the repeated task you want to do, for instance scrolling down the page.
In that case, you would write a test case for each style change, scroll the page while measuring with the Frame Timing API
https://github.com/GoogleChrome/frame-timing-polyfill
Each test would expect the frame rate to be above a certain value.
I want my frame to be always on top, but I want it to be really on top. I want no other windows to hide it, even if they are also "always on top". I'm using wx.STAY_ON_TOP and wx.FRAME_FLOAT_ON_PARENT, but still there are windows that appear on top of mine. Also, the taskbar appears on top of my frame, while I'd like it to be behind my frame.
I've tried a lot of things that didn't work, detailed here.
Any idea how to make my frame really on top?
Because their is no standard method in doing so, as it is most often an undesired effect, you can possibly achieve this by frequently setting the topmost flag again to "overrule" any other applications going for the topmost position. You could do this using a timer which sets the value every x ms, or you can try and only set the ontop flag again when the window has lost focus. The events to set the ontop flag are:
EVT_SET_FOCUS
EVT_KILL_FOCUS
Try using this:
wx.Frame.SetFocus()
