Scroll calendar to prev/next month

[skligys]

I was thinking how I could see the previous/next months in the new calendar tooltip, and could not see a good way.

• One option is to always display 3 months (as in cal -3) but then the tooltip is huge.
• Awesome WM scrolls to previous month on left click and to next month on right click but that doesn't match left/right click actions in other modules.
• Mouse scroll up/down could scroll months but right now scrolling seems to be reserved to executing external executables.

Please advise!

@maximbaz I'll go if possible by using https://developer.gnome.org/gtkmm/stable/classGtk_1_1Calendar.html
and replace the tooltip widget with the calendar one that can give an output like this:

Using gtkmm you can IMO do something like this.
Get the tooltip window using:

auto window = label_. get_tooltip_window();
auto widget = window.get_child()
window.remove(widget); // In order to replace current widget
window.add(GtkCalendar);

I don't know if it's gonna work, but it's worth a try. 😄

Thanks for the input, this is an interesting idea!

(keeping a mind that I have very little C++ experience 😛) here's what I managed to investigate so far:

• most importantly, in update() method label_.get_tooltip_window() always returns null for me, I speculate that the window is only being created when the tooltip is actually being rendered on screen and update() is called before that
• trying to create a completely new window for the tooltip doesn't crash waybar, but then the tooltip simply doesn't show up at all:

  auto gtkCalendar = Gtk::Calendar();
  auto gtkCalendarWindow = Gtk::Window();
  gtkCalendarWindow.add(gtkCalendar);
  gtkCalendar.show();
  label_.set_tooltip_window(gtkCalendarWindow);

• trying to find some examples of drawing this calendar I only found this reference: https://gitlab.gnome.org/GNOME/gnome-panel/-/blob/master/modules/clock/calendar-window.c#L1598

Any hints are very appreciated 🙂

@skligys or anyone else, if you have some ideas, do feel free to jump in 😉

@maximbaz You may need to use set_has_tooltip(true), can you try?

[Alexays]

And try to set the tooltip on the event_box parent

[maximbaz]

Thanks! As far as I could see setting set_has_tooltip(true) on label_, event_box_ or event_box_.get_parent() had no effect; get_tooltip_window() still returns null and set_tooltip_window() as in the snippet above still does nothing, nothing appears on hover.

Hi @skligys , @maximbaz calendar scrolling is supported by the clock module. See Clock WIKI + there's open #2019 which implements of module action redefinition

[LukashonakV]

Hi @skligys , @maximbaz #2019 is merge into the master.
So now your are able to redefine Clock actions on your wish.
Please see:

1. Module actions config
2. Wiki clock

If it's Ok for you , please close an issue.
Thank you

[skligys]

Yes, thank you very much for code changes. I rebuilt waybar, and am using calendar with your changes. Works very well for me.

Closing the bug.
