GTK +改变字体旋转按钮 [英] GTK+ change font to spin button

问题描述

  flow_spin = gtk_spin_button_new_with_range（100,1500,25）;我在GTK +中创建了一个旋转按钮。 
  

我想改变它的字体和大小。我搜索了一下，以便找到一种解决方法，因为它看起来似乎旋转按钮小部件本身并没有改变它的格式，但没有任何工作。

这：

  flow_spin.Child.ModifyFont（FontDescription.FromString（Courier 16））; 
  

以及此，无效：

  flow_spin.Markup =< span size ='38000'>大文字< / span>; 
  

至于这个，加号和减号按钮变大了，但是文字区域保持不变：

  gtk_widget_set_size_request（flow_spin，50，50）; 
  

我看看是否可能有类似这样的方法？

  gtk_label_set_markup（GTK_LABEL（label），< span font ='8'foreground ='black'weight ='normal'> 100< / span>） ; 
  

由于我是C以及GTK +的初学者，因此我们将不胜感激。

解决方案

Gtk支持用于样式的CSS。您可以使用gtk_css_provider_load_from_file（）在您的程序中加载CSS文件。

所以，只需在GtkWidget上添加样式提供程序即可。

I created a spin button in GTK+ like this:

flow_spin = gtk_spin_button_new_with_range (100,1500,25);

and I want to change it's font and size. I googled in order to find a workaround because it seems that the spin button widget doesn't change it's format natively, but nothing worked.

This:

flow_spin.Child.ModifyFont(FontDescription.FromString("Courier 16"));

as well as this, didn't work:

flow_spin.Markup = "<span size='38000'>big text</span>";

As for this, the plus and minus buttons got bigger, but the text area remained the same size:

gtk_widget_set_size_request ( flow_spin,50, 50);

I look if possibly for a method, similar to this ?

gtk_label_set_markup (GTK_LABEL (label), "<span font='8' foreground='black' weight='normal'>100</span>");

Since I am a beginner at C as well as GTK+, any suggestions would be appreciated.

解决方案

Gtk supports CSS for styling. You can load a CSS file in your program with gtk_css_provider_load_from_file().

So, just add a style provider on GtkWidget you want to stylish.
