vb.net - ventana - Cómo mover la forma sin el borde del formulario(visual studio)
mover un formulario sin barra de titulo vb net (5)
Prueba esto:
Public Const WM_NCLBUTTONDOWN As Integer = &HA1
Public Const HT_CAPTION As Integer = &H2
<DllImportAttribute("user32.dll")> _
Public Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
End Function
<DllImportAttribute("user32.dll")> _
Public Shared Function ReleaseCapture() As Boolean
End Function
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown, Panel1.MouseDown
If e.Button = Windows.Forms.MouseButtons.Left Then
ReleaseCapture()
SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0)
End If
End Sub
Utiliza las llamadas a la API de Windows para indicar a la ventana que el usuario está sosteniendo la ventana. Como puede ver, se adjunta al evento MouseDown de formulario, pero puede utilizar cualquier control que desee usar para arrastrar el formulario.
Estoy haciendo una aplicación de formulario de Windows en Visual Studio 2013 Express. Para hacer que la aplicación se vea más personalizada y atractiva, diseñé los formularios en mi aplicación. Establecí el estilo del borde del formulario en ''NINGUNO'' e hice mi propio título y los botones de salir / min / máximo. SIN EMBARGO, la única forma de mover el formulario en tiempo de ejecución es arrastrando la barra de título, y no puedo hacer esto con el borde del formulario y la barra de título desaparecidos. Entonces, ¿es posible mover el formulario sin la barra de título y el borde? ¿Tal vez si tengo mi propia barra de título y trato de controlar la posición de las formas? ¿Cuál es la mejor manera de hacerlo?
Gracias
Si no desea utilizar las llamadas a la API de Windows, puede hacerlo con los eventos de formulario:
Private isMouseDown As Boolean = False
Private mouseOffset As Point
'' Left mouse button pressed
Private Sub Form1_MouseDown(sender As Object,e As MouseEventArgs) Handles Form1.MouseDown
If e.Button = Windows.Forms.MouseButtons.Left Then
'' Get the new position
mouseOffset = New Point(-e.X, -e.Y)
'' Set that left button is pressed
isMouseDown = True
End If
End Sub
'' MouseMove used to check if mouse cursor is moving
Private Sub Form1_MouseMove(sender As Object, e As MouseEventArgs) Handles Form1.MouseMove
If isMouseDown Then
Dim mousePos As Point = Control.MousePosition
'' Get the new form position
mousePos.Offset(mouseOffset.X, mouseOffset.Y)
Me.Location = mousePos
End If
End Sub
'' Left mouse button released, form should stop moving
Private Sub Form1_MouseUp(sender As Object, e As MouseEventArgs) Handles Form1.MouseUp
If e.Button = Windows.Forms.MouseButtons.Left Then
isMouseDown = False
End If
End Sub
Tan simple como esto, agregue este código a su Form-Class:
#Region " Move Form "
'' [ Move Form ]
''
'' // By Elektro
Public MoveForm As Boolean
Public MoveForm_MousePosition As Point
Public Sub MoveForm_MouseDown(sender As Object, e As MouseEventArgs) Handles _
MyBase.MouseDown '' Add more handles here (Example: PictureBox1.MouseDown)
If e.Button = MouseButtons.Left Then
MoveForm = True
Me.Cursor = Cursors.NoMove2D
MoveForm_MousePosition = e.Location
End If
End Sub
Public Sub MoveForm_MouseMove(sender As Object, e As MouseEventArgs) Handles _
MyBase.MouseMove '' Add more handles here (Example: PictureBox1.MouseMove)
If MoveForm Then
Me.Location = Me.Location + (e.Location - MoveForm_MousePosition)
End If
End Sub
Public Sub MoveForm_MouseUp(sender As Object, e As MouseEventArgs) Handles _
MyBase.MouseUp '' Add more handles here (Example: PictureBox1.MouseUp)
If e.Button = MouseButtons.Left Then
MoveForm = False
Me.Cursor = Cursors.Default
End If
End Sub
#End Region
