我正在为Autodesk Inventor创建一个AddIn(3D绘图软件),目前我正在玩位置限制。
我创建了一个自定义用户菜单,用于快速编辑某些值,在本例中为高程和方向值。
首先,我使用textbox.textchanged
事件来更改约束值。但这不是100%的工作。按高程1000的示例将改变高程4次(按每个数字)。
现在我开始使用validated event
了。这样做效果更好,但我希望在按下Enter
按钮时让文本框启动验证。为此,我掀起了这个,但这不正确,我很确定。我该怎么写这个呢?
下面的代码有效,但我希望有一个正确的方法来实现结果。
Private Sub tbElevationValue_TextChanged(sender As Object, e As EventArgs) _
Handles tbElevation.Validated
' If the elevation parameter and textbox value are the same
' The sub must be aborted
If CDbl(tbElevation.Text) = oElevationParameter.Value * 10 Then Exit Sub
' Check the entered value
Dim oValue As Double
If tbElevation.Text = "" Then
oValue = 0
tbElevation.Text = 0
Else
oValue = tbElevation.Text
End If
' Set the parameter value
oElevationParameter.Value = oValue / 10
' Update the document
EM_AddIn.StandardAddInServer.m_inventorApplication.ActiveDocument.Update()
End Sub
Private Sub tbOrientation_TextChanged(sender As Object, e As EventArgs) _
Handles tbOrientation.Validated
' If the orientation parameter and textbox value are the same
' The sub must be aborted
If CDbl(tbOrientation.Text) = cRandiansToDegrees(oOrientationParameter.Value) Then Exit Sub
' Check the entered value
Dim oValue As Double
If tbOrientation.Text = "" Then
oValue = 0
tbOrientation.Text = 0
Else
oValue = tbOrientation.Text
End If
' Set the parameter value
oOrientationParameter.Value = cDegreesToRandians(oValue)
' Update the document
EM_AddIn.StandardAddInServer.m_inventorApplication.ActiveDocument.Update()
End Sub
Private Sub OrientationElevationEnterKey_Pressed(sender As Object, e As Windows.Forms.KeyEventArgs) Handles tbElevation.KeyUp, tbOrientation.KeyUp
If e.KeyCode = Windows.Forms.Keys.Enter Then
CType(sender, Windows.Forms.TextBox).Parent.Focus()
CType(sender, Windows.Forms.TextBox).Focus()
End If
End Sub

我认为你的方式正确。为每个TextBox对象注册key_down事件可能会很痛苦,但你的想法很好。
您可以将key_down事件侦听器设置为您的表单。
尝试这样的事情:
Private Sub Main_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.KeyCode.Enter Then
MyBase.Focus() ' this will cause the currently focused control to validate
End If
End Sub
