带有自定义标题栏的表单

Question

我使用这段代码来最大化和恢复我的自定义表单。但是当窗体最大化时，它仍然可以拖动，我使用计时器来拖动窗体。

Private Sub btnMaximize_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMaximize.Click, lblTitle.MouseDoubleClick
    Dim maximizeHeight As Integer = Screen.PrimaryScreen.WorkingArea.Height
    Dim maximizeWidth As Integer = Screen.PrimaryScreen.WorkingArea.Width
    Dim maximizeLocation As Point = New Point(0, 0)
    Dim fullscreen As Boolean = False

    If Me.Height = maximizeHeight Or Me.Width = maximizeWidth Or Me.Location = maximizeLocation Then
        fullscreen = True
    Else
        fullscreen = False
    End If

    If fullscreen = True Then
        Me.Size = New Size(1000, 500)
        Me.Left = (Screen.PrimaryScreen.WorkingArea.Width - Me.Width) / 2
        Me.Top = (Screen.PrimaryScreen.WorkingArea.Height - Me.Height) / 2
    ElseIf fullscreen = False Then
        Me.Location = New Point(0, 0)
        Me.Size = New Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height)
    End If
End Sub

Private Sub pnlBar_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lblTitle.MouseDown
    MoveTmr.Start()
    refpositions()
End Sub

Private Sub MoveTmr_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles MoveTmr.Tick
    Me.Location = oloc - ocur + System.Windows.Forms.Cursor.Position
    refpositions()
End Sub

Private Sub pnlBar_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lblTitle.MouseUp
    MoveTmr.Stop()
    refpositions()
End Sub

Private Sub RszTmr_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles RszTmr.Tick
    Me.Size = appSize - curPos + Cursor.Position
    refpositions()
End Sub

Answer 1

您可以用代码或可视化方式创建面板，然后放置dock。顶部然后，您可以在窗口的侧面或中间放置一个标签，在窗口的左侧放置一个图片框创建按钮以关闭最小化和最大化或其他按钮，并在上面添加好友代码以通过标题栏移动表单，就像在windows中一样

我使用Mousedown、Mouseup和Mousemove事件来移动我的表单。

Public Class Form1

Private Is_Dragged As Boolean = False
Private M_DownX As Integer
Private M_DownY As Integer

Private Sub Form1_MouseDown(sender As Object, e As MouseEventArgs) Handles Me.MouseDown

    If e.Button = MouseButtons.Left Then
        Is_Dragged = True
        M_DownX = e.X
        M_DownY = e.Y
    End If

End Sub
Private Sub Form1_MouseUp(sender As Object, e As MouseEventArgs) Handles Me.MouseUp

    If e.Button = MouseButtons.Left Then
        Is_Dragged = False
    End If

End Sub
Private Sub Form1_MouseMove(sender As Object, e As MouseEventArgs) Handles Me.MouseMove

    If Is_Dragged Then
        Dim tmp_pnt As Point = New Point()

        tmp_pnt.X = Me.Location.X + (e.X - M_DownX)
        tmp_pnt.Y = Me.Location.Y + (e.Y - M_DownY)
        Me.Location = tmp_pnt
        tmp_pnt = Nothing

    End If

End Sub

End Class

最大化我的状态。

Private Sub Btn_Main_Max_Click(sender As Object, e As EventArgs) Handles Btn_Main_Max.Click

    Static IsAlreadyResized As Boolean

    If Not IsAlreadyResized Then
        Me.WindowState = FormWindowState.Maximized
        IsAlreadyResized = True
        Exit Sub
    End If

    If IsAlreadyResized Then
        Me.WindowState = FormWindowState.Normal
        IsAlreadyResized = False

    End If

 End Sub

使：

Dim fullscreen As Boolean = False

一个类变量。

然后编辑此代码以适应您的变量：

Private Sub Mover_Tick(sender As System.Object, e As System.EventArgs) Handles Mover.Tick
    If fullscreen = false Then
         Dim pt As New Point((Me.Location.X + (MousePosition.X - mPosX)), (Me.Location.Y + (MousePosition.Y - mPosY)))
         Me.Location = pt
         mPosX = MousePosition.X
         mPosY = MousePosition.Y
    End If
End Sub

编辑：

还要实现这一点：

Private Sub Title_StartDrag(sender As System.Object, e As MouseEventArgs) Handles Title.MouseDown
    mPosX = MousePosition.X
    mPosY = MousePosition.Y
    If e.Button = Windows.Forms.MouseButtons.Left Then
        Mover.Start()
    End If
End Sub

Private Sub Title_StopDrag(sender As System.Object, e As MouseEventArgs) Handles Title.MouseUp
    Mover.Stop()
End Sub

你也可以说“我”来让事情变得更简单。WindowsState=FormWindowsState。最大化
