I'm not sure I understand where you're clicking, can you include a screenshot?

Please also specify the specific xpra version you are using at both ends. (as per ReportingBugs)

Xpra version is 2.3.4.Cannot include screenshot. I clicked the application of gedit on win7 task manager,which remoted from rhel7.4, but no minimized. I discovered this problem just on the gedit of rhel7.4.

OK, so we're talking about the task manager icon, that's a bit clearer now.

version at both ends
Xpra version is 2.3.4.
Is that at both ends?

Why is this not running the latest supported version? (2.4.2 right now)

Please post the client log by adding -d metadata to the command line.

It seems to not trigger minimized event when I clicked the icon of gedit from task manager, but clicking the gedit minimization button can minimize.

I find that the gedit remoted from rhel7.4 is without border, so the window stytle cannot include "WS_MINIMIZEBOX".

I can reproduce this with any recent server OS. This looks like a "feature" of those newer gnome applications with CSD.
Client-Side-Decoration strikes again: by moving the responsibility for drawing the window controls and the title bar to the client application, they make it much more difficult to remote those applications when there isn't the same set of features available the operating system we remote to.

I'm really not sure how to solve this: forcing the window border would make it really ugly as the window would then have two title bars with the two sets of minimize and maximize buttons...

Unless you can suggest another solution, I will probably close this as 'wontfix'.

Nothing we can do. It's a gnome feature.

Note: there is a project called gtk3-nocsd which removes CSD - this may work for you.
Just be aware that Debian / Ubuntu packaged it wrong so it can cause crashes: #1981.
