Gtk＃多文件过滤器 [英] Gtk# Multiple File Filter

问题描述

我只想在GTK＃File Chooser中显示图像文件

  fc.SelectMultiple = true; 
 FileFilter filter = new FileFilter（）; 
 filter.Name =图片文件; 
 filter.AddPattern（* .jpg; *。jpeg; *。png; *。tif; *。bmp; *。gif; *。tiff）; 
 fc.Filter = filter; 
  

这不起作用。文件选择器不显示任何文件。
有人可以建议我采取适当的方式来做到这一点。 来自文档的样本， AddPattern 方法用于添加单个 一次模式。与WinForms实现和类似的实现不同，它并不是一次设置所有模式，而是为之前添加的任何模式添加一个额外的模式。

因此，请尝试分割您的命令：

  fc.SelectMultiple = true; 
 FileFilter filter = new FileFilter（）; 
 filter.Name =图片文件; 
 filter.AddPattern（*。jpg）; 
 filter.AddPattern（*。jpeg）; 
 filter.AddPattern（*。png）; 
 filter.AddPattern（*。tif）; 
 filter.AddPattern（*。bmp）; 
 filter.AddPattern（*。gif）; 
 filter.AddPattern（*。tiff）; 
 fc.Filter = filter; 
  

I want to display only image files in GTK# File Chooser

        fc.SelectMultiple = true;
        FileFilter filter  = new FileFilter();
        filter.Name = "Image files";
        filter.AddPattern ("*.jpg;*.jpeg;*.png;*.tif;*.bmp;*.gif;*.tiff");
        fc.Filter = filter;

This does not work.The file chooser does not show any Files. Can someone suggest me a proper way to do this.

解决方案

As shown in the sample from the docs, the AddPattern method is meant for adding a single pattern at a time. In contrast to the WinForms implementation and similar implementations, it does not set all patterns at a time, instead it adds one additional pattern to whatever has been added before.

Therefore, try splitting up your command:

fc.SelectMultiple = true;
FileFilter filter  = new FileFilter();
filter.Name = "Image files";
filter.AddPattern("*.jpg");
filter.AddPattern("*.jpeg");
filter.AddPattern("*.png");
filter.AddPattern("*.tif");
filter.AddPattern("*.bmp");
filter.AddPattern("*.gif");
filter.AddPattern("*.tiff");
fc.Filter = filter;
