我试图开发一个自定义的组合框(其是在工具条)在其项目5的字体样,我将显示的,因为他们看。
问题:我不能设定大小的每一个项目。 该 MeasureItem 事件不会着火,我不能找出原因。
不错但不完全是我的节奏! ^^
这是我的代号:
Public CorpusFontStyleTitre1 As Font = New Font(New FontFamily("Lato"), 18, FontStyle.Bold, 3)
Public CorpusFontStyleTitre2 As Font = New Font(New FontFamily("Lato"), 16, FontStyle.Underline Or FontStyle.Bold, 3)
Public CorpusFontStyleTitre3 As Font = New Font(New FontFamily("Lato"), 14, FontStyle.Underline Or FontStyle.Bold, 3)
Public CorpusFontStyleTitre4 As Font = New Font(New FontFamily("Lato"), 12, FontStyle.Underline, 3)
Public CorpusFontStyleCorpsdeTexte As Font = New Font(New FontFamily("Lato"), 12, FontStyle.Regular, 3)
Public Structure CorpusFontStyleItem
Dim strTextStyleName As String
Dim fontTextStyle As Font
Public Overrides Function ToString() As String
Return strTextStyleName
End Function
End Structure
Private Sub frmCorpusManagement_Load(sender As Object, e As EventArgs) Handles MyBase.Load
LoadcmbFontStyle()
cmbFontStyle.ComboBox.DrawMode = DrawMode.OwnerDrawFixed
AddHandler cmbFontStyle.ComboBox.DrawItem, AddressOf cmbFontStyle_DrawItem

End Sub
Private Sub cmbFontStyle_MeasureItem(ByVal sender As Object, ByVal e As MeasureItemEventArgs)
Select Case e.Index

e.ItemHeight = 50

e.ItemHeight = 40

e.ItemHeight = 30

e.ItemHeight = 20

e.ItemHeight = 10
End Select
End Sub
Private Sub cmbFontStyle_DrawItem(ByVal sender As Object, ByVal e As DrawItemEventArgs)
e.DrawBackground()
Dim myItem As CorpusFontStyleItem = DirectCast(cmbFontStyle.Items(e.Index), CorpusFontStyleItem)
e.Graphics.DrawString(myItem.strTextStyleName, myItem.fontTextStyle, New SolidBrush(Color.Black), e.Bounds)
e.DrawFocusRectangle()
End Sub
