Add proper looking context menu item

‎08-22-2013 08:30 AM

Hi,

 

I have no problem adding my own menu item to any given context menu, however, it does not suit the look and feel of act! (see picture)

 

Any ideas?

I ran into a similar problem this week and after searching for a while, I had to end up writing my own DrawMenu and MeasureMenu methods if I wanted  the menu options looking like Act.

 

Basically, right now, your menu is being drawn by windows, and it doesn't know the custom desgin code Act uses (the icon area in gray, rest is white background, blue highlight border etc etc)

 

You need to set the OwnerDraw property of the menu item to true, and add eventhandlers to the DrawItem and MeasureItem.

 

Here's the code that helped me quite a bit with drawing: http://www.codeproject.com/Articles/4332/Putting-Images-Next-To-MenuItems-In-A-Menu-in-C

 

 

I still have to mess around with mine but it looks close enough at the moment.

Here are two classes you can use to mimic the act! menu style. One is for an icon menu item and the second is for a seperator menu item

 

Usage Example:

Friend Shared WithEvents GroupTreeViewMenu As System.Windows.Forms.MenuItem

 

GroupTreeViewMenu = New IconMenuItem("Group Tree", CType(GetEmbeddedIcon("TreeView16.ico"), Icon), New EventHandler(AddressOf OnMenuItemClick), Nothing)

 

 

Public Class IconMenuItem : Inherits System.Windows.Forms.MenuItem

    Private m_Icon As Icon
    Private m_Font As Font
    Private m_Checked As Boolean


    Public Sub New(ByVal text As String, ByVal icon As Icon, ByVal onClick As EventHandler, ByVal shortcut As Windows.Forms.Shortcut)
        MyBase.New(text, onClick, shortcut)
        OwnerDraw = True
        m_Font = New Font("Microsoft Sans Serif", 8)
        m_Checked = False
        m_Icon = icon
    End Sub

    Public Overloads Sub Dispose()
        m_Font.Dispose()
        m_Font = Nothing
        m_Icon.Dispose()
        m_Icon = Nothing
        MyBase.Dispose()
    End Sub

    Public Property Icon() As Icon
        Get
            Return m_Icon
        End Get
        Set(ByVal value As Icon)
            m_Icon = value
        End Set
    End Property

    Public Property isChecked() As Boolean
        Get
            Return MyBase.Checked
        End Get
        Set(ByVal value As Boolean)
            MyBase.Checked = value
        End Set
    End Property

    Protected Overrides Sub OnMeasureItem(ByVal e As Windows.Forms.MeasureItemEventArgs)
        Dim sf As StringFormat = New StringFormat

        sf.HotkeyPrefix = Drawing.Text.HotkeyPrefix.Show
        sf.SetTabStops(60, New Single() {0})

        MyBase.OnMeasureItem(e)

        e.ItemHeight = 22
        e.ItemWidth = CInt(e.Graphics.MeasureString(GetRealText(), m_Font, 10000, sf).Width) + 10

            sTemp = sTemp & Convert.ToChar(9) & System.ComponentModel.TypeDescriptor.GetConverter(GetType(Windows.Forms.Keys)).ConvertToString(kKeys)
        End If
        Return sTemp
    End Function

    Protected Overrides Sub OnDrawItem(ByVal e As Windows.Forms.DrawItemEventArgs)

Re: Add proper looking context menu item

‎08-26-2013 03:25 PM

i would have to search some of my code, but im sure that the menus are built with Infragistics controls..

 

I just imported the reference to Infragistics and with a few lines of code create a menu item, then added it to the menu.. was simple and straight forward.. of course if they stop using Infragistics then the menu items in a newer ACT version might not work, but for all the current versions it works fine
