信息系统开发平台OpenExpressApp - 支持WPF主题样式

  OpenExpressApp中有一个项目【OpenExpressApp.Module.WPF.Style】,它作为以后UI样式扩展用,以前只是放在那里,其实没有做什么工作,主要也就是告诉大家后期会增加主题样式。前期做框架、做引擎时,由于侧重点不一样,所以有时经常被人说做出来的东西真丑:)所以最近就花了两天把样式扩展加进来了。目前主要从网上下载了微软的一些样式,还没有扩充OEA内部控件的样式,界面如下图:

ThemeManager

  在【OpenExpressApp.Module.WPF.Style】中有一个ThemeManager.cs单元,这是主题管理的唯一一个类,其余都是各个主题的样式文件。这些都是从网上下载的,由于比较简单,就不做具体介绍了,只把代码附上:

代码
public static class ThemeManager
{
public static ResourceDictionary GetThemeResourceDictionary(string theme)
{
if (theme != null)
{
// Assembly assembly = Assembly.LoadFrom("OpenExpressApp.Module.WPF.Style");
string packUri = String.Format(@"/OpenExpressApp.Module.WPF.Style;component/{0}/Theme.xaml", theme);
return Application.LoadComponent(new Uri(packUri, UriKind.Relative)) as ResourceDictionary;
}
return null;
}

public static string[] GetThemes()
{
string[] themes = new string[]
{
"朴素","朦胧蓝","ExpressionDark", "ExpressionLight", "RainierOrange", "RainierPurple", "RainierRadialBlue",
"ShinyBlue", "ShinyRed", "ShinyDarkTeal", // "ShinyDarkGreen",
"ShinyDarkPurple",
"DavesGlossyControls", "WhistlerBlue", "BureauBlack", "BureauBlue", "BubbleCreme",
"UXMusingsRed", "UXMusingsGreen", "UXMusingsRoughRed", "UXMusingsRoughGreen", "UXMusingsBubblyBlue"
};
return themes;
}

public static void ApplyTheme(this Application app, string theme)
{
ResourceDictionary dictionary
= ThemeManager.GetThemeResourceDictionary(theme);

if (dictionary != null)
{
app.Resources.MergedDictionaries.Clear();
app.Resources.MergedDictionaries.Add(dictionary);
}
}

public static void ApplyTheme(this ContentControl control, string theme)
{
ResourceDictionary dictionary
= ThemeManager.GetThemeResourceDictionary(theme);

if (dictionary != null)
{
control.Resources.MergedDictionaries.Clear();
control.Resources.MergedDictionaries.Add(dictionary);
}
}

#region Theme

/// <summary>
/// Theme Attached Dependency Property
/// </summary>
public static readonly DependencyProperty ThemeProperty =
DependencyProperty.RegisterAttached(
"Theme", typeof(string), typeof(ThemeManager),
new FrameworkPropertyMetadata((string)string.Empty,
new PropertyChangedCallback(OnThemeChanged)));

/// <summary>
/// Gets the Theme property. This dependency property
/// indicates ....
/// </summary>
public static string GetTheme(DependencyObject d)
{
return (string)d.GetValue(ThemeProperty);
}

/// <summary>
/// Sets the Theme property. This dependency property
/// indicates ....
/// </summary>
public static void SetTheme(DependencyObject d, string value)
{
d.SetValue(ThemeProperty, value);
}

/// <summary>
/// Handles changes to the Theme property.
/// </summary>
private static void OnThemeChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
string theme = e.NewValue as string;
if (theme == string.Empty)
return;

ContentControl control
= d as ContentControl;
if (control != null)
{
control.ApplyTheme(theme);
}
}

#endregion
