如何将鼠标光标设置到标签上的指定位置?
How to set the mouse cursor to a specified location on a label?
所以我在 visual basic 6.0 中开发了这个游戏,这是一个迷宫游戏,我希望我的鼠标光标设置在带有迷宫的表单的开始标签上,一旦表单被激活并获得焦点!
Dim label1 As New label=Start
我过去使用 Windows API 完成过类似的任务。在下面的示例中,一个表单包含一个名为 'Label1' 的标签,该标签位于该表单的某处。当表格被激活时,光标将以 'Label1':
为中心
Option Explicit
Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long
Private Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
End Type
Private Sub Form_Activate()
Dim wr As RECT
Dim tb As Long
Dim le As Long
Dim x As Long
Dim y As Long
'calculate coordinates
Call GetWindowRect(Me.hwnd, wr) 'window coordinates
tb = (Me.Height - Me.ScaleHeight) - (Me.Width - Me.ScaleWidth) / 2 'title bar height
le = (Me.Width - Me.ScaleWidth) * 0.5 'left edge of client area
'calculate center of label
x = wr.Left + ScaleX(le + Label1.Left + Label1.Width * 0.5, Me.ScaleMode, vbPixels)
y = wr.Top + ScaleY(tb + Label1.Top + Label1.Height * 0.5, Me.ScaleMode, vbPixels)
SetCursorPos x, y
End Sub
