Hi ptitjoz,

The same question came up before, like here.

Hello Peter
Thank you for your answer

I added these lines:


lib$ = HUGLIB$("gtk")
IMPORT "gtk_widget_modify_bg(long,int,long)" FROM lib$ TYPE void

and


gtk_widget_modify_bg(Win1,0,"green")

The color changes well but does not match

Small note, in the documentation, it says that this command is deprecated.

gtk_widget_modify_bg has been deprecated since version 3.0 and should not be used in newly-written code.

Use gtk_widget_override_background_color() instead

But how to use it?

Regards

Hi ptitjoz,

Looking at your last questions in the several posts, it seems that you require a more sophisticated usage for HUG. So it may be better for you to use GTK directly, outside the HUG context. You can check and rip the code from HUG for a quick start.

Please realize that HUG is a limited framework, which allows you to quickly create a basic GUI. It does not have advanced features.

It would be even better to use BaCon's native GUI functions, which are designed to approach a graphical toolkit like GTK in a abstract manner.

Having said that, below a simple example of how to set a color of a window. You can find this code in HUG also.

INCLUDE hug

lib$ = HUGLIB$("gtk")

IMPORT "gtk_widget_modify_bg(long,int,long)" FROM lib$ TYPE void ALIAS BGCOLOR

win = WINDOW("Hello world", 200, 200)

gdkcol = g_malloc(HUG_DEFAULT_WIDGET_SIZE)
gdk_color_parse("#00FF00", gdkcol)

BGCOLOR(win, 0, gdkcol)

DISPLAY

The 'gtk_widget_modify_bg' function is deprecated for GTK3. However, HUG is based on GTK2 so never mind that remark in their documentation.

Also, please note that this forum is meant to support BaCon. For specific questions about how to use GTK2, please refer to their documentation or wiki.

Bonsoir ptitjoz,

Obviously you are not bothering the forum

Any question related to BaCon is welcome, how basic it may be. So do not hesitate to keep asking questions! But outside BaCon the forum has its limitations

Cordialement,
Peter

Hello
yes I understand your answer.
My problem is that I know English very poorly and I don't know much about Linux and gtk.
But have no fear, I will be asking more questions or giving you suggestions on Bacon.
Best regards
