how to enable middle mouse button emulation? #4607
-
|
Hi, xpra works great for our legacy X11/Motif app, except it requires a middle mouse button for some functionality. On XQuartz on macOS, we can work around this by enabling middle mouse button emulation, which treats option+left click as a middle mouse click. Unfortunately, with xpra, I have not been able to get middle mouse button emulation to work. I have tried the various solutions here, but they do not seem to work: https://askubuntu.com/questions/160164/how-do-i-enable-middle-mouse-button-emulation. Does xpra have its own setting for middle mouse button emulation? Thanks, |

Doesn't your mac have a middle button? I fail to see how this could be an xpra bug. |

No, it does not have a middle mouse button, so macOS cannot send a middle click. I would like the X server to be able to convert option + left-click into a middle click. XQuartz does this, and Xorg used to be able to do this (haven't tested in a long time). |

Apparently adding Nonetheless, I would like to be able to do this with Xpra, since acquiring a real 3-button mouse is not a realistic option for all of our users. |

I think this should be implemented as a client option, not a server-side fixed setting, something like: Please file an xpra feature request issue. |
