有没有一种合适的方式来调整项目的权利从.NET Windows.Forms的?
Is there a proper way to align items to the right for ListBoxes from the .net Windows.Forms?
您可以使用
example_box = ListBox()
example_box.RightToLeft = RightToLeft.Yes
这使右对齐,而且打印您的项目从右到左。同样的格式做一些非常奇怪的事情在这里:
This enables the right alignment, but also prints your items right to left. Also the formatting does some really strange things here:
%一二4.72被显示为一二4.72%
'% one two 4.72' gets displayed as 'one two 4.72 %'
有关数字只是这工作得很好,但感觉相当靠不住的。有没有更好的办法呢?
For digits only this works quite well, but feels rather wonky. Are there better solutions?
从右至左的布局是为在阿拉伯和Hewbrew文化,他们写的文字从右到左。这也会影响文本渲染,你找到了一个副作用。您需要使用所有者描述得到它,你想要的方式。添加一个新类到您的项目并粘贴下面所示的code。编译。从工具箱顶部的新控件到窗体中。
RightToLeft layout is meant for the Arabic and Hewbrew cultures, they write text right-to-left. It also affects how text is rendered, you found a side-effect. You need to use owner-draw to get it the way you want it. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.
using System;
using System.Drawing;
using System.Windows.Forms;
class ReverseListBox : ListBox {
public ReverseListBox() {
this.DrawMode = DrawMode.OwnerDrawFixed;
}
protected override void OnDrawItem(DrawItemEventArgs e) {
e.DrawBackground();
if (e.Index >= 0 && e.Index < this.Items.Count) {
var selected = (e.State & DrawItemState.Selected) == DrawItemState.Selected;
var back = selected ? SystemColors.Highlight : this.BackColor;
var fore = selected ? SystemColors.HighlightText : this.ForeColor;
var txt = this.Items[e.Index].ToString();
TextRenderer.DrawText(e.Graphics, txt, this.Font, e.Bounds, fore, back, TextFormatFlags.Right | TextFormatFlags.SingleLine);
}
e.DrawFocusRectangle();
}
}
