在GTK中显示字体选择对话框＃ [英] Showing Font Selection Dialog in GTK#

问题描述

在我的gtk＃应用程序im试图显示字体选择dialog.Im试图使用下面的代码，但FontSelectionDialog构造函数需要一些参数也控制执行等待一个字体被选中设置字符串 font

有人能指导我吗？

  Gtk.FontSelectionDialog fs = new FontSelectionDialog（）
 fs.Show（）; 
 font = fs.FontName; 
  

解决方案

根据其他问题更新

这应该有助于：

  FontSelectionDialog dialog = null; 
尝试{
 dialog = new FontSelectionDialog（Choose a font）; 
 dialog.Run（）; 
 var name = dialog.FontName; 
 var pattern = @^（？< fontName>。*）\s（？< fontSize> \d +（?: \.\d +）？）$; 
 var regex = new Regex（pattern）; 
 var match = regex.Match（name）; 
 if（match.Success）
 {
 var fontName = match.Groups [fontName]。Value; 
 var fontSize = float.Parse（match.Groups [fontSize]。Value）; 
 var font = new System.Drawing.Font（fontName，fontSize）; 
} 
} finally {
 if（dialog！= null）
 dialog.Destroy（）; 
} 
  

In MY gtk# Application im trying to show the font selection dialog.Im trying to use the following code,but the FontSelectionDialog constructor need some arguments also does the control execution wait for a font to be selected to set the string font

Can someone guide me?

Gtk.FontSelectionDialog fs = new FontSelectionDialog()
            fs.Show ();
            font=fs.FontName;

解决方案

Updated according to additional question

This should help:

FontSelectionDialog dialog = null;
try {
    dialog = new FontSelectionDialog("Choose a font");
    dialog.Run ();
    var name = dialog.FontName;
    var pattern = @"^(?<fontName>.*)\s(?<fontSize>\d+(?:\.\d+)?)$";
    var regex = new Regex(pattern);
    var match = regex.Match(name);
    if(match.Success)
    {
        var fontName = match.Groups["fontName"].Value;
        var fontSize = float.Parse(match.Groups["fontSize"].Value);
        var font = new System.Drawing.Font(fontName, fontSize);
    }
} finally {
    if (dialog != null)
        dialog.Destroy ();
}
