Previously, the only way to select all the module labels was with the
following kind of selector:
```css
.modules-left > widget > label,
.modules-center > widget > label,
.modules-right > widget > label {
/* ... */
}
```
(and a matching block for the `box` containers).
Now, this can be expressed as
```css
label.module, box.module {
/* ... */
}
```
This reverts commit 2d33c20231 and
reapplies various patches for memory leaks.
The reason for the revert was a bug for a maximum duration interval
which caused sleep_for() to cause unpredictable behavior.
There were two main issues with fmtlib and C++20 mode:
- `fmt::format` defaults to compile-time argument checking and requires
using `fmt::runtime(format_string)` to bypass that.
- `std::format` implementation introduces conflicting declarations and
we have to specify the namespace for all `format`/`format_to` calls.
Mouse-over tooltips set on the label only appear once the mouse hovers
over exactly the label. Other apps (e.g. firefox) show the tooltip once
the pointer hovers the button. Not solely its label. With this commit we
get the same behaviour.
Fixes issue where the class parameters in style.css would have no
effect.
The CSS now references the GtkButton instead of the GtkLabel. Removing
all style-classes from the custom module GtkButton however removes
any properties set via style.css. Thus, the default classes 'flat' and
'text-button' are added on every update of these modules.
The AButton class is designed as full a substitute to ALabel. The
GtkButton attribute 'button_' is initialized with a label. This
label can the be referenced by the subsequent inheritors of AButton
instead of the GtkLabel attribute 'label_' of ALabel.
For convenience a GtkLabel* 'label_' attribute is added to AButton.
If the button cannot be clicked it is disabled, effectively acting
like its label predecessor.
GtkButton seems to catch one-click mouse events regardless of the
flags set on it. Therefore, 'signal_pressed' is connected to a
function creating a fake GdkEventButton* and calling 'handleToggle'
(for details on this possible bug in GTK see:
https://stackoverflow.com/questions/45334911 )
In accordance with other GtkButtons (i.e. the sway/workspace ones)
set_relief(Gtk::RELIEF_NONE) is called on the 'button_' instance.
When adding a custom module with a name, e.g.:
```jsonc
{
...,
"custom/foo#bar": { },
...
}
```
The custom module does not retain the `bar` class as it should, because
all the classes are replaced with the runtime output:
1b4a7b02f4/src/modules/custom.cpp (L141-L147)
Avoid removing the module instance name class so css class behavior is
consistent between all modules.
This commit fixes the issue where the process would restart immediately
and the thread would sleep after the process has restarted, and not
before.
Fixes#621
