我正在实现一个需要在面板中拖放图像框的应用程序.图像框是从程序中动态添加的,因此我在面板中将autoscroll属性设置为true.但是当我拖出底部的框时面板尺寸减小.我在面板中放置了autosize属性false.面板停靠在另一个面板上.我想在运行时设置面板的大小.我怎样才能实现这一点.
public form1(int[,] dummy,int columnSize,int rowSize)
{
this.dummy= dummy;
numOfColumns = columnSize;
numOfRows = rowSize;
getData();
addIds = addIdArray;
data = mylist;
InitializeComponent();
//panel1.MinimumSize = new Size(columnSize * 40,rowSize * 40);
//panel1.Height = rowSize * 40;
//panel1.Width = columnSize * 40;
//panel4.Height = rowSize * 40;
//panel4.Width = columnSize * 40;
int x,y;
Structures.EmptyRectSpace space = new Structures.EmptyRectSpace();
for (int i = 0; i < data.Count; i++)// set picture Boxes
{
space = (Structures.EmptyRectSpace)data[i];
x = space.startingJ;
y = space.startingI;
int h,w;
h = space.length;
w = space.width;
p = new PictureBox();
p.Width = w * 40;
p.Height = h * 40;
p.BackColor = Color.DarkGreen;
p.Image = Properties.Resources.v;
p.BorderStyle = BorderStyle.FixedSingle;
p.Name = addIdArray[i].ToString();
p.Location = new Point((x + 1 - w) * 40,(y + 1 - h) * 40);
this.panel1.Controls.Add(p);
}
foreach (Control c in this.panel1.Controls)
{
if (c is PictureBox)
{
c.MouseDown += new MouseEventHandler(pictureBox1_MouseDown);
}
}
this.panel1.DragOver += new System.Windows.Forms.DragEventHandler(this.panel1_DragOver);
panel1.DragOver += new DragEventHandler(panel1_DragOver);
panel1.DragDrop += new DragEventHandler(panel1_DragDrop);
panel1.AllowDrop = true;
panel2.AllowDrop = true;
foreach (Control c in this.panel2.Controls)
{
c.MouseDown += new MouseEventHandler(pictureBox1_MouseDown);
}
this.panel2.DragOver += new System.Windows.Forms.DragEventHandler(this.panel2_DragOver);
panel2.DragOver += new DragEventHandler(panel2_DragOver);
panel2.DragDrop += new DragEventHandler(panel2_DragDrop);
}
这是包含面板的表单的构造函数.当它加载时,必须将图片框添加到面板中并实现面板的拖放事件.
请帮帮我..
解决方法
除非我在代码中以编程方式设置最大宽度,否则我无法工作.设计师的最大宽度是多少并无关紧要(或者如果设置了最大宽度).
int newWidth = 200; panel.MaximumSize = new Size(newWidth,panel.Height); panel.Size = new Size(newWidth,panel.Height);
