Wpf Panel Background problem

由 狂风中的少年 提交于 2021-02-04 16:11:11
问题 When i don't set background of my panel i can not get mouse events on that. why this behaviour? I am able to get mouse events on panel by setting Background to Transparent which is null by default. Whats the difference between Background null and Transparent? 回答1: When Background=null it doesn't issue any drawing command to MILCore when rendering, and it doesn't count the control's entire area in hit testing. When Background=Transparent , it issues an ordinary drawing command to MILCore when

How does IOS manage memory of backgrounded apps?

由 a 夏天 提交于 2021-01-29 07:02:38
问题 I have an IOS app that during testing seems to work fine until... The app has been in the background for quite some time, say 24 hours... and meanwhile lots of activity has taken place in other apps (videos, audio, location... battery going low... lots of memory being used). Then when I bring my app back into the foreground, it acts glitchy such as having no audio... and then crashes after a short while. I KNOW this is not the best description, but it has only happened once and I'm not asking

问题 In the interest of avoiding an XY problem, I'm trying to set up an iTerm profile to do the following when I hit the hotkey. cd to ~/my/directory/ start an http server in the background let me stay in ~/my/directory/ The command I'm working with so far is cd ~/my/directory/ && python -m SimpleHTTPServer 8000 &> /dev/null & This works great for starting the server on the project root. The problem is, after it starts running in the background, my pwd is NOT ~/my/directory/. I guess that part is
