HUG MSGDIALOG ignores BASEXFTDPI

[barryk]

This seems like a bug. In the Puppy Forum we are test 'proxy-setup', to which I have added internationalizartion and dpi size adjustment:

murga-linux.com/puppy/viewtopic.php?p=502836#502836

At the start of the program:

OPTION INTERNATIONAL TRUE
INCLUDE "hug.bac"

REM fix window font layout regardless of dpi...
REM 78 is the xft dpi when I designed the layout...
HUGOPTIONS("BASEXFTDPI 78")

font_sans$="DejaVu Sans 12"
font_mono$="Monospace 13"

Puppies deault xft dpi is 78. I tested with Xft.dpi in ~/.Xresources set to 96 and found that the main window drew bigger on the screen so all the text continued to fit very nicely.

However, not so for MSGDIALOG:

REM define some info boxes...
err_dlg1=MSGDIALOG(INTL("Sorry, the password entries are not the same"),400,100,3,2)
yes_dlg1=MSGDIALOG(INTL("Great, you have modified the proxy server settings. Note, you can see the result in files /etc/profile.d/http_profile and /etc/profile.d/ftp_profile. However, MOST IMPORTANT, you must reboot for this to take effect"),500,160,0,1)
no_dlg1=MSGDIALOG(INTL("You have chosen NOT to use a proxy server. Note, if you previously did have a proxy server enabled, you MUST REBOOT for the change to take effect"),500,140,0,1)

...these boxes remain the same size, so the text is truncated.

Note also, I specified fixed sizes for the fonts, so:
label_pass=MARK(INTL("Password:"),80,20)
ATTACH(mainwin,label_pass,10,190)
FONT(label_pass,font_sans$)
password1=PASSWORD(150,20)
ATTACH(mainwin,password1,100,190)
TEXT(password1,password$)
FONT(password1,font_mono$)

...with the reasoning that if a user has a GTK theme with different size default fonts then by using FONT I will ensure that proxy-setup window always remains looking the same.
However, it seems that I cannot apply FONT to MSGDIALOG

...so, I wonder if it might be possible for a global font specification, say "Sans 12", that will override the GTK default and apply to all widgets.

Peter, I am keeping you busy

Hi Barry,

Well, for the 'BASEXFTDPI' option this is a bug - I simply forgot that the FILEDIALOG and MSGDIALOG widgets have their own resizing function. This is fixed now in HUG v0.36.

The font situation is a different story. It may be possibly to apply a generic style to the whole GUI, but this morning the site with GTK documentation is not reachable. I will check it when they are back up again.

Peter

Your wish is my command

Such a setting relates to the behavior of HUG as a whole, it seems this should be added as another HUGOPTION.

So now you can set the global font for the whole of the HUG program as follows:

INIT
HUGOPTIONS("FONT Arial 24")
<...more statements...>
DISPLAY

Of course the 'Arial 24' is just an example, can be any other font name, e.g. 'Sans Italic 12', or 'Courier 14' and so on.

It is available in HUG v0.37.

Best regards
Peter

Hi, I tried it, but it doesn't work for me. I tried different things, but only the default GTK font displays. Here is the start of my proxy-setup program:

REM setup proxy server for wget
REM Barry Kauler, my first BaCon GTK program using HUG
REM (c) Copyright Barry Kauler Nov 2010, license GPL v3 /usr/share/doc/legal
REM 20110310 internationalization and dpi improvements in BaCon

REM .po/.mo files have 'charset=UTF-8', so LANG must also have .utf8 (or .UTF-8)...
REM however puppy users often set en_US not en_US.utf8, so append if missing...
lang$=EXEC$("echo -n $LANG | sed -e 's%\\.utf8%%' -e 's%\\.UTF-8%%' -e 's%$%.utf8%'")
SETENVIRON "LANG", lang$

OPTION INTERNATIONAL TRUE
INCLUDE "hug.bac"

REM fix window font layout regardless of dpi...
REM 78 is the Xft.dpi in /root/.Xresources when I designed the layout...
HUGOPTIONS("BASEXFTDPI 78")

REM User may have GTK theme font size too big/small. set to required size...
HUGOPTIONS("FONT DejaVu Sans 12")

[Pjot]

Well, are you sure you are using the latest HUG include?

This is my code:

INCLUDE "hug.bac"

INIT

HUGOPTIONS("FONT Arial 24")

win = WINDOW("Hello world", 200, 100)
msg = MSGDIALOG("Goodbye world", 300, 200, 0, 1)

SHOW(msg)
DISPLAY

Below this is the result. Note that the titlebar of the dialog must be changed in your Window manager.

regards
Peter

I was using hug.bac 0.37. I downloaded 0.38, downloaded and compiled latest bacon.bac from beta directory.

I used your example, and it still doesn't work.

Note, your example has "INIT", but I thought the docs stated that isn't required? Anyway, putting it in or leaving it out makes no difference.

Wary Puppy has GTK 2.20.1 -- I wonder if that matters?

Dear Peter,

I used hug 0.38 and got the same result as Barry

With kind regards,
vovchik

PS. Could it be a .gtkrc-2.0 setting that indicates font type and size that is preventing the selection and resizing?

[Pjot]

Barry, Vovchik,

So tried in my Puppy virtual environment and you folks are right. It took me some time to find out the cause of the problem, but it seems that my global font implementation needed a 'global Xsettings Manager' (whatever that may be). Probably this is not available in Puppy Linux?

Anyway I have found another way of setting the font for the whole HUG application which works both for my systems and also for Puppy. At least it works for Wary 5.1.1.

Can you try again with HUG v0.39?

Thanks,
Peter

[vovchik]

Dear Peter,

Thanks. A very interesting finding on your part regarding font management. I tried HUG 0.39 and it does change the font size and attributes (Bold, Oblique, etc.) but not the font itself. It still comes up default - in my case as DejaVu Sans - no matter what I specify. So HUG 0.39 is more than halfway there already but, in my case, misses the actual font name.

With kind regards,
vovchik

Hi Vovchik,

You must specify a font which actually exists in your Linux environment, otherwise GTK will fall back to the default.

If you run 'bacongui' and activate the dialog for changing the font, you can see a list of fonts available on your system. Can you try to exactly use one of these with HUG?

Thanks,
Peter

EDIT: there appeared to be a typo in the HUG include after all, please get the latest and try again...

[vovchik]

Dear Peter,

It now works like a charm. Thanks!

With kind regards,
vovchik

Yes, it is absolutely fantastic!

I have written a HOWTO to get consistent layout:
