傳統(tǒng)的窗口菜單都是左對(duì)齊，是否可以右對(duì)齊，或窗口菜單左右分開(kāi)呢？
當(dāng)然可以！
新建一個(gè)工程，添加菜單（本例需要3列），添加四個(gè)按鈕控件，一個(gè)時(shí)間控件
添加以下代碼：
Option Explicit
Private Type menuItemInfo
cbSize As Long
fMask As Long
fType As Long
fState As Long
wID As Long
hSubMenu As Long
hbmpChecked As Long
hbmpUnchecked As Long
dwItemData As Long
dwTypeData As String
cch As Long
End Type
Private Declare Function SetMenuItemInfo Lib "user32" Alias "SetMenuItemInfoA" (ByVal hMenu As Long, ByVal un As Long, ByVal
bool As Boolean, lpcMenuItemInfo As menuItemInfo) As Long
Private Declare Function GetMenuItemInfo Lib "user32" Alias "GetMenuItemInfoA" (ByVal hMenu As Long, ByVal un As Long, ByVal
b As Long, lpMenuItemInfo As menuItemInfo) As Long
Private Declare Function GetMenu Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function DrawMenuBar Lib "user32" (ByVal hwnd As Long) As Long
Public a As Integer
Private Sub Command1_Click()
Unload Me
Me.Show
Dim my_menuItemInfo As menuItemInfo
Dim return_value As Long
With my_menuItemInfo
.cbSize = 44
.fMask = 16
.cch = 128
.dwTypeData = Space$(128)
End With
return_value = GetMenuItemInfo(GetMenu(Me.hwnd), 3, 1, my_menuItemInfo)
my_menuItemInfo.fType = 16384
return_value = SetMenuItemInfo(GetMenu(Me.hwnd), 3, 1, my_menuItemInfo)
DrawMenuBar GetMenu(Me.hwnd)
Me.Refresh
Me.WindowState = 1
End Sub
Private Sub Command2_Click()
Dim my_menuItemInfo As menuItemInfo
Dim return_value As Long
With my_menuItemInfo
.cbSize = 44
.fMask = 16
.cch = 128
.dwTypeData = Space$(128)
End With
return_value = GetMenuItemInfo(GetMenu(Me.hwnd), 0, 1, my_menuItemInfo)
my_menuItemInfo.fType = 16384
return_value = SetMenuItemInfo(GetMenu(Me.hwnd), 0, 1, my_menuItemInfo)
DrawMenuBar GetMenu(Me.hwnd)
Me.Refresh
Me.WindowState = 1
End Sub
Private Sub Command3_Click()
Unload Me
Me.Show
Dim my_menuItemInfo As menuItemInfo
Dim return_value As Long
With my_menuItemInfo
.cbSize = 44
.fMask = 16
.cch = 128
.dwTypeData = Space$(128)
End With
return_value = GetMenuItemInfo(GetMenu(Me.hwnd), 1, 1, my_menuItemInfo)
my_menuItemInfo.fType = 16384
return_value = SetMenuItemInfo(GetMenu(Me.hwnd), 1, 1, my_menuItemInfo)
DrawMenuBar GetMenu(Me.hwnd)
Me.Refresh
Me.WindowState = 1
End Sub
Private Sub Command4_Click()
Unload Me
Me.Show
Dim my_menuItemInfo As menuItemInfo
Dim return_value As Long
With my_menuItemInfo
.cbSize = 44
.fMask = 16
.cch = 128
.dwTypeData = Space$(128)
End With
return_value = GetMenuItemInfo(GetMenu(Me.hwnd), 2, 1, my_menuItemInfo)
my_menuItemInfo.fType = 16384
return_value = SetMenuItemInfo(GetMenu(Me.hwnd), 2, 1, my_menuItemInfo)
DrawMenuBar GetMenu(Me.hwnd)
Me.Refresh
Me.WindowState = 1
End Sub
Private Sub Timer1_Timer()
If Me.WindowState = 1 Then Me.WindowState = 0
End Sub
運(yùn)行一下，如何？
注意四個(gè)按鈕不同的一個(gè)參數(shù)，那表示左邊有幾個(gè)菜單項(xiàng)
