4x less memory consumption than bl-hotcorners

"Pretty simple hot corners implementation for X server written in modern C++"

Not sure about the mem use, but the cpu usage is about the same as bl-hotcorners, and a C++ program is likely to be more efficient than a python script.

It polls the mouse position every 60ms, which is a bit wasteful to my taste, but this can be changed before compiling, by editing src/Manager.h (line#22), in the extracted directory (I used 300):

const int UPDATE_INTERVAL_IN_MS = 60;

cd to lwa-hot-corners-master/, and if you want to install in $HOME/bin, do

export DESTDIR=''
PREFIX="$HOME" make
PREFIX="$HOME" make install

Create a config file, such as .config/lwa-hotcornersrc, like this:

top_left_command=gmrun
top_right_command=
bottom_left_command=
bottom_right_command=
hold_duration=500
disable_on_fullscreen=false

To run it at login, add this command to your autostart

lwa-hot-corners ~/.config/lwa-hotcornersrc &

Hi! I am author of the program.

I've updated repository.

Changes:
- by default logs are disabled
- disable calls with empty command
- change default update interval in order to make update less often
- allow to change interval via config(update_interval=value in ms)

Please feel free to provide more feedback!

Hello and good day!

I am wanting to use your script in a few different wm's, but am having trouble with the hotcorners not working unless another window is opened. Openbox works as expected.

The others I am using are fluxbox, pekwm, and jwm. Hotcorners works fine in these so long as another window is open as well. ( I should note that I just grabbed the script, and did not "install" as such. Unsure if this could have an impact.)

The fullscreen option in the rc makes no difference to this behavior.

Anyway, really digging you work! On Openbox, lwa-hot-corners is flawless so far.)

I used lwa-hot-corners today!

I had an interesting issue, I got it running in a terminal using the & append, and it worked, but I would lose it when I closed the shell.

I tried running lwa-hot-corners ~/.config/lwa-hotcornersrc & from the Run Program dialog using alt-F2, but it didn't seem to activated from what I was monitoring in htop.

I did find the nohup command as an option, and that seems to be working for me now, as

nohup lwa-hot-corners ~/.config/lwa-hotcornersrc &

I'm wondering if I've done something wrong? And if I need the 'nohup' command in the autostart script?
