[英]How to move a button from an array of buttons by mouse? C#
I'm really new to C# coding. 我真的是C#编码的新手。 I got an array of buttons and I want to move the button I'm left clicking by mouse.
我有一系列按钮,我想移动鼠标左键单击的按钮。 Any advice?
有什么建议吗?
private void CreateTable(Button[] Tabla)
{
int horizotal = 45;
int vertical = 45;
for (int i = 0; i < Tabla.Length; i++)
{
Tabla[i] = new Button();
Tabla[i].BackColor = Color.Azure;
Tabla[i].Size = new Size(45, 45);
Tabla[i].Location = new Point(horizotal, vertical);
if ((i == 14) || (i == 29) || (i == 44) || (i == 59) || (i == 74) ||
(i == 89) || (i == 104) || (i == 119) || i == 134 || i == 149 || i == 164 || i == 179 || i == 194 || i == 209)
{
vertical = 45;
horizotal = horizotal + 45;
}
else
vertical = vertical + 45;
this.Controls.Add(Tabla[i]);
}
}
This is the code that creates my buttons. 这是创建我的按钮的代码。
First of all, you add mouseeventhandler your buttons then you declare the mouseeventshandler like this. 首先,添加mouseeventhandler您的按钮,然后像这样声明mouseeventshandler。
private void CreateTable(Button[] Tabla)
{
int horizotal = 45;
int vertical = 45;
for (int i = 0; i < Tabla.Length; i++)
{
Tabla[i] = new Button();
Tabla[i].BackColor = Color.Azure;
Tabla[i].Size = new Size(45, 45);
Tabla[i].Location = new Point(horizotal, vertical);
if ((i == 14) || (i == 29) || (i == 44) || (i == 59) || (i == 74) ||
(i == 89) || (i == 104) || (i == 119) || i == 134 || i == 149 || i == 164 || i == 179 || i == 194 || i == 209)
{
vertical = 45;
horizotal = horizotal + 45;
}
else
vertical = vertical + 45;
Tabla[i].MouseDown += new MouseEventHandler(button_down);//adding Down handler
Tabla[i].MouseMove += new MouseEventHandler(button_move);//adding Move handler
this.Controls.Add(Tabla[i]);
}
}
private void button_down(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
starting.X = e.Location.X;
starting.Y = e.Location.Y;
}
}
private void button_move(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
((Button)sender).Left += e.Location.X - starting.X;
((Button)sender).Top += e.Location.Y - starting.Y;
}
}
sender is caller of the handler and we know it is a button. 发送者是处理程序的调用者,我们知道它是一个按钮。 So we can use it like this.
因此我们可以像这样使用它。 ı think this code is perfect for you but your problem is using buttons for letter.
我认为该代码对您而言是完美的,但是您的问题是使用字母按钮。 You can use picturebox for letter and theyare more proper than buttons.
您可以将图片框用于字母,它们比按钮更合适。 Finally I think you should declare field your buttons array.
最后,我认为您应该声明字段您的按钮数组。
