定義

執行設定這個控制項的指定範圍的工作。Performs the work of setting the specified bounds of this control.

protected:
 virtual void SetBoundsCore(int x, int y, int width, int height, System::Windows::Forms::BoundsSpecified specified);
protected virtual void SetBoundsCore (int x, int y, int width, int height, System.Windows.Forms.BoundsSpecified specified);

參數

x
Int32 Int32 Int32 Int32

控制項的新 Left 屬性值。The new Left property value of the control.

y
Int32 Int32 Int32 Int32

控制項的新 Top 屬性值。The new Top property value of the control.

width
Int32 Int32 Int32 Int32

控制項的新 Width 屬性值。The new Width property value of the control.

height
Int32 Int32 Int32 Int32

控制項的新 Height 屬性值。The new Height property value of the control.

specified
BoundsSpecified BoundsSpecified BoundsSpecified BoundsSpecified

BoundsSpecified 值的位元組合。A bitwise combination of the BoundsSpecified values.

範例

下列程式碼會覆寫SetBoundsCore方法,以確保控制項維持固定的大小。The following code example overrides the SetBoundsCore method to ensure that the control remains a fixed size. 此範例中,您需要直接或間接衍生自類別Control類別。This example requires that you have a class that is either directly or indirectly derived from the Control class.

protected:
   virtual void SetBoundsCore( int x, int y, int width, int height, BoundsSpecified specified ) override
   {
      // Set a fixed height and width for the control.
      UserControl::SetBoundsCore( x, y, 150, 75, specified );
   }
protected override void SetBoundsCore(int x, int y, 
   int width, int height, BoundsSpecified specified)
{
   // Set a fixed height and width for the control.
   base.SetBoundsCore(x, y, 150, 75, specified);
}
Protected Overrides Sub SetBoundsCore(x As Integer, _
  y As Integer, width As Integer, _
  height As Integer, specified As BoundsSpecified)
   ' Set a fixed height and width for the control.
   MyBase.SetBoundsCore(x, y, 150, 75, specified)
End Sub

備註

一般而言,對應至不包含在繫結參數specified參數傳入其目前值。Typically, the parameters that correspond to the bounds not included in the specified parameter are passed in with their current values. 例如, HeightWidth,或X或是Y的屬性Location屬性可以傳入控制項的目前執行個體的參考。For example, the Height, Width, or the X or Y properties of the Location property can be passed in with a reference to the current instance of the control. 不過的接受傳入的所有值,並套用至控制項。However all values passed in are honored and applied to the control.

boundsSpecified參數代表的控制項項目Bounds變更您的應用程式。The boundsSpecified parameter represents the elements of the controls Bounds changed by your application. 比方說,如果您變更Size的控制項boundsSpecified參數值是Size的值BoundsSpecifiedFor example, if you change the Size of the control, the boundsSpecified parameter value is the Size value of BoundsSpecified. 不過,如果Size調整以回應Dock所設定的屬性boundsSpecified參數值是None的值BoundsSpecifiedHowever, if the Size is adjusted in response to the Dock property being set, the boundsSpecified parameter value is the None value of BoundsSpecified.

注意

在 Windows Server 2003 系統上,大小Form受到監視的高度與最大像素寬度。On Windows Server 2003 systems, the size of a Form is restricted by the maximum pixel width and height of the monitor.

給繼承者的注意事項

當覆寫SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified)衍生類別時,請務必呼叫基底類別的SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified)方法,以強制變更控制項的界限。When overriding SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified) in a derived class, be sure to call the base class's SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified) method to force the bounds of the control to change. 在衍生的類別可以加入大小限制SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified)方法。Derived classes can add size restrictions to the SetBoundsCore(Int32, Int32, Int32, Int32, BoundsSpecified) method.
