Whisker Menu: adapt its appearance to our GTK theme in Xfce

For a long time I have been using Whisker Menu like my menu in panel Xfce Regardless of my distribution changes, however lately I have had to spend many hours in front of the monitor at night and I prefer that the colors of things that I use a lot are darker.

At first I thought that Whisker was not following / using my theme gtk, but then I found out by words of its creator which is treated as a regular or normal window (It cannot be a Gtk Menu due to the Widgets it uses cause problems) and therefore if it follows the colors of the theme, but those of the windows, not those that correspond to the menus:

Whisker Menu is a regular window and therefore it matches the GTK theme of regular windows. It can not be a GtkMenu because of the widgets it uses (believe me, I tried), so it does not match the theming of menus

But right there Graeme details how this can be easily modifiable through adjustments in the file .gtkrc-2.0.

In my case I went from this:

Whisker Menu by default

Modified Whisker Menu

To this:

And I did it according to what he mentions in the aforementioned page, the following code modifies the right or categories panel and the menu. bg refers to the background, and fg to the front, in these cases to the texts. The 3 states NORMAL, ACTIVE y PRELIGHT they refer to the unselected, selected and selected state respectively but not with the cursor over it.

Set the colors for Whisker Menu

style "WhiskerNegro"
{
bg[NORMAL] = "#404040"
bg[ACTIVE] = "#606060"
bg[PRELIGHT] = "#808080"
fg[NORMAL] = "#ccc"
fg[ACTIVE] = "#fff"
fg[PRELIGHT] = "#fff"
}
widget "whiskermenu-window*" style "WhiskerNegro"

While this modifies the left panel or view of the elements:

style "ArbolNegroNumix"
{
base[NORMAL] = "#2D2D2D"
base[ACTIVE] = "#D64937"
text[NORMAL] = "#ccc"
text[ACTIVE] = "#fff"
}
widget "whiskermenu-window*TreeView*" style "ArbolNegroNumix"

And finally this changes the appearance of the input / search box:


style "Busqueda"
{
base[NORMAL] = "#2D2D2D"
base[ACTIVE] = "#D64937"
text[NORMAL] = "#ccc"
text[ACTIVE] = "#fff"
}
widget "whiskermenu-window*GtkEntry*" style "Busqueda"

The colors are of course "to the consumer's taste", so adapt them according to your needs. For the changes to take effect it is necessary to close the session and log in again, however if you prefer to avoid the hassle or have important things open you can restart the Xfce panel with xfce4-panel -r
