« on: July 20, 2016, 02:44:17 am »
I use slackware linux.

Hi, can you disable the symbol browser in the code completion plugin's setting dialog?

It is a known issue for wx 3.x under linux.(this issue has asked many times before in our forum) :)

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Yes, it can simply avoid by disable codecompletion plugin, if so, class symbol browser will be gone. I do not think its a good idea.
Thanks all the same.

There is an option to disable just the symbol browser, but leave code completion enabled.
