Cara: Mengubah Tipe Kursor

Contoh ini menunjukkan cara mengubah Cursor pointer mouse untuk elemen tertentu dan untuk aplikasi.

Contoh ini terdiri dari file Extensible Application Markup Language (XAML) dan kode di belakang file.

Contoh

Antarmuka pengguna dibuat, yang terdiri dari ComboBox untuk memilih , sepasang RadioButton objek yang diinginkan Cursoruntuk menentukan apakah perubahan kursor hanya berlaku untuk satu elemen atau berlaku untuk seluruh aplikasi, dan Border yang merupakan elemen tempat kursor baru diterapkan.

<StackPanel>
  <Border Width="300">
    <StackPanel Orientation="Horizontal"
                HorizontalAlignment="Center">
      <StackPanel Margin="10">
        <Label HorizontalAlignment="Left">Cursor Type</Label>
        <ComboBox Width="100"
                  SelectionChanged="CursorTypeChanged"
                  HorizontalAlignment="Left"
                  Name="CursorSelector">
          <ComboBoxItem Content="AppStarting" />
          <ComboBoxItem Content="ArrowCD" />
          <ComboBoxItem Content="Arrow" />
          <ComboBoxItem Content="Cross" />
          <ComboBoxItem Content="HandCursor" />
          <ComboBoxItem Content="Help" />
          <ComboBoxItem Content="IBeam" />
          <ComboBoxItem Content="No" />
          <ComboBoxItem Content="None" />
          <ComboBoxItem Content="Pen" />
          <ComboBoxItem Content="ScrollSE" />
          <ComboBoxItem Content="ScrollWE" />
          <ComboBoxItem Content="SizeAll" />
          <ComboBoxItem Content="SizeNESW" />
          <ComboBoxItem Content="SizeNS" />
          <ComboBoxItem Content="SizeNWSE" />
          <ComboBoxItem Content="SizeWE" />
          <ComboBoxItem Content="UpArrow" />
          <ComboBoxItem Content="WaitCursor" />
          <ComboBoxItem Content="Custom" />
        </ComboBox>
      </StackPanel>
      <!-- The user can select different cursor types using this ComboBox -->
      <StackPanel Margin="10">
        <Label HorizontalAlignment="Left">Scope of Cursor</Label>
        <StackPanel>
          <RadioButton Name="rbScopeElement" IsChecked="True"
                       Checked="CursorScopeSelected">Display Area Only</RadioButton>
          <RadioButton Name="rbScopeApplication"
                       Checked="CursorScopeSelected">Entire Appliation</RadioButton>
        </StackPanel>
      </StackPanel>
    </StackPanel>
  </Border>
  <!-- When the mouse pointer is over this Border -->
  <!-- the selected cursor type is shown -->
  <Border Name="DisplayArea" Height="250" Width="400"
          Margin="20" Background="AliceBlue">
    <Label HorizontalAlignment="Center">
      Move Mouse Pointer Over This Area
    </Label>
  </Border>
</StackPanel>

Kode berikut di belakang membuat SelectionChanged penanganan aktivitas yang dipanggil ketika jenis kursor diubah di ComboBox. Pernyataan pengalih memfilter pada nama kursor dan mengatur Cursor properti yang Border bernama DisplayArea.

Jika perubahan kursor diatur ke "Seluruh Aplikasi", OverrideCursor properti diatur ke Cursor properti Border kontrol. Ini memaksa kursor untuk berubah untuk seluruh aplikasi.

    ComboBox source = e.Source as ComboBox;

    if (source != null)
    {

        // by setting the Cursor property
        switch (selectedCursor.Content.ToString())
