简介应该是绘画文字后,窗口重绘时清除了那一块区域。所以放窗体的Paint事件里就行了。Private?Sub?Form1_Paint(ByVal?sender?As?Object,?ByVal?e?As?System.Windows.Forms.PaintEventArgs)?Handles?Me.Paint ‘?在?Paint?事件参数中提供了?Graphics.?无需?Create.Using?

C#中使用DrawString绘制文本时怎样使文本居中或右对齐
楼上正解,之所以混在一起,是因为你没擦掉,0-0。擦掉的方法就同楼上所说,有两种:
1. super.paintComponent(g),会调用组件的原始界面重绘一次,这样你上次绘制上去的文本就不在了,也就相当于擦除了;
2. g.clearRect(x,y,w,h),这个就更直白了,就是擦除这个区域
string 和 thread 的区别
format.LineAlignment = StringAlignment.Center; // 更正: 垂直居中
format.Alignment = StringAlignment.Center; // 水平居中
RectangleF 排版框 = new Rectangle(Point.Zero, new Size(nWidth, nHeight));
g.DrawString(_ShowName, stringFont, Brushes.Black, 排版框, format);
C# DrawString函数,怎么有效限制绘制文字的宽度?
thread有时会表示针线的线(用毛/棉做的线),而string没有这种用法。但是表示绳子的时候,几乎相同,但是thread会比较细长,而string只是质量轻,没有对细度和长度方面的暗示。

java入门问题,用了drawString却不显示字串
Graphics 对象有 SetClip(Rectangle) 和 ResetClip() 两个方法,可以先通过前者指定一个有效绘图区域,绘制后再重置有效区域。
比如该 Graphics 的实际是 (0, 0, 200, 200),指定一个 (50, 50, 100, 100) 的矩形作为有效区域,那么超出该范围的部分不会被绘制在 Graphics 上。
Java中c.getGraphics().drawString()是什么意思?
因为 class PanelTest extends JPanel
{
public void PaintComponent(Graphics g)//方法名应该小写,才能重写。
{
super.paintComponent(g);
g.drawString("Hello Java", 75, 100);
}
所以,改为以下:class PanelTest extends JPanel {
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawString("Hello Java", 75, 100);
}
就可以。
否则,不能重写该方法。
整句应该是
Image c=Image.createImage(128,128);
Graphics g=c.getGraphics();
g.drawString("string");
你可能就是
Graphics g=c.getGraphics();
这句不清楚
这句程序的意思是
得到c的画笔g,然后你在后面就可以用g来绘画这张c了
