AdiIRC

It's all about the font you use, "themes" are just color themes, but some also set a custom font, make sure you are using a fixed width font such as Consolas.

Edit. AdiIRC uses "Verdana" as default font, it is not fixed width.

Thank you!

So, I went in File|Options|Fonts,
clicked the: Font|'Messages'|'Browse' button, and in the "Choose font" window there I changed it from Verdana to Consolas.

Just one thing I noticed, regarding this:

just color themes, but some also set a custom font,

I've noticed that in the: Font|'Messages'|'Browse' button|"Choose font" window ,
the "Font" dropdown value remains "Verdana" in all cases (i.e. unless I manually change it to e.g. "Consolas"), no matter what theme I switch to.
e.g. if I switch (from the 'Default' theme) to the 'mirc' theme -----> as I saw, mirc.ini contains this line: "CONF_font=FixedSys 9"
then in the "Choose font" window, the Font value still remains "Verdana", instead of changing to "FixedSys".

And, if I tick the "Use Default" checkbox, then it restores to "Verdana",
but, then, it remains "Verdana" no matter what theme I switch to.

Shouldn't the displayed "Font" value be changed according to the currently used theme?
i.e. shouldn't it display the theme's used font, e.g. FixedSys, unless you have manually changed to a different font, e.g. Consolas?

If a theme has a custom font and you check the "Apply Fonts" when applying a theme, the custom font will be overridden.

When you select "Use default" it will always revert to "Verdana" which is the default AdiIRC font.

If you reset theme to default, it will again use "Verdana" since it's the default AdiIRC font.

The "mirc" theme is very old, it's possible that adiirc doesn't pick up the old "CONF_font=" option, I'll check that.

Thank you for fixing this!

I just noticed this:

STR
in a clean 2.9 beta 2017/7/10 x64 installation (i.e. installing 2.8 and then typing /betaup ),
open AdiIRC (it will use the 'Default' theme)
and go to Options|Fonts (its main page).
It will be like this:

('Nicklist font weight' dropdown)| Prefix --> -
('Treebar font weight' dropdown) | Server --> -
('Links font weight') ----------------------> 'Underline' checked

Now (for the purpose of testing) go to File|Themes and switch to the 'Default' theme [and of course have all 10 checkboxes in the 'Apply theme' window checked].
Here is how the Fonts page will be:

('Nicklist font weight' dropdown)| Prefix --> -
('Treebar font weight' dropdown) | Server --> 'Bold' checked
('Links font weight') ----------------------> 'Underline' checked

i.e. the '('Treebar font weight' dropdown) | Server' now has the 'Bold' checkbox enabled.

I have edited the previous post, making the STR as minimal as possible.

Yeah the "Treebar font weight" for servers used to be bold, I fixed this for next beta, thanks.
