C# DevExpress XtraMessageBox自定义字体,字体大小,自定义按钮大小,自定义Icon

1.使用XtraMessageBoxForm,自定义Icon

2.重写XtraMessageBoxForm,自定义消息字体,标题字体

3.注册XtraMessageBoxForm的Showing事件,自定义按钮字体及按钮大小

 

具体代码如下,只写了简单两种方法,可自己扩展,赋值MessageBoxIcon可以显示想要的Icon

 

    public static class UIMessageBox
    {
        static UIMessageBox()
        {
            MessageBoxForm.MessageBoxFont = new Font("Arial", 14F); //定义字体类型
        }

        static readonly Icon MessageBoxIcon = null;


        public static void Show(string message)
        {
            ShowInternal(null, message, "Notice", SystemIcons.Information, DialogResult.OK);
        }

        public static void Show(Control owner, string message)
        {
            ShowInternal(owner, message, "Notice", SystemIcons.Information, DialogResult.OK);
        }

private static DialogResult ShowInternal(Control owner, string message, string caption, Icon messageIcon, params DialogResult[] dialogResults) { MessageBoxForm form = new MessageBoxForm(); form.Icon = MessageBoxIcon; XtraMessageBoxArgs args = new XtraMessageBoxArgs(owner, message, caption, dialogResults, messageIcon, 0); args.Showing += Args_Showing; return form.ShowMessageBoxDialog(args); } private static void Args_Showing(object sender, XtraMessageShowingArgs e) { MessageButtonCollection buttons = e.Buttons as MessageButtonCollection; SimpleButton btn = null; foreach (var dialog in (DialogResult[])Enum.GetValues(typeof(DialogResult))) { btn = buttons[dialog] as SimpleButton; if (btn != null) { btn.Size = new Size(Convert.ToInt32(btn.Width * 1.2), Convert.ToInt32(btn.Height * 1.2)); //按钮大小 btn.Font = e.Form.Font; //按钮字体 } } } } internal class MessageBoxForm : XtraMessageBoxForm { internal static Font MessageBoxFont = new Font("Arial", 10F); public MessageBoxForm() { Appearance.Font = MessageBoxFont; } protected override FormPainter CreateFormBorderPainter() { return new MessageBoxFormPainter(this, LookAndFeel); } } internal class MessageBoxFormPainter : FormPainter { internal MessageBoxFormPainter(Control owner, ISkinProvider provider) : base(owner, provider) { } protected override void DrawText(GraphicsCache cache) { string text = Text; if (text == null || text.Length == 0 || TextBounds.IsEmpty) return; AppearanceObject appearance = new AppearanceObject(GetDefaultAppearance()); appearance.Font = Owner.Font; appearance.TextOptions.Trimming = Trimming.EllipsisCharacter; Rectangle r = RectangleHelper.GetCenterBounds(TextBounds, new Size(TextBounds.Width, appearance.CalcDefaultTextSize(cache.Graphics).Height)); DrawTextShadow(cache, appearance, r); cache.DrawString(text, appearance.Font, appearance.GetForeBrush(cache), r, appearance.GetStringFormat()); } protected override int CalcTextHeight(Graphics graphics, AppearanceObject appearance) { return (int)(graphics.MeasureString(Text, Owner.Font).Height); //标题栏的高度 } }

 

调用时:

UIMessageBox.Show("This is a message");
