ITransformProvider.Resize(Double, Double) 메서드

정의

컨트롤의 크기를 조정합니다.Resizes the control.

public:
 void Resize(double width, double height);
public void Resize (double width, double height);
abstract member Resize : double * double -> unit
Public Sub Resize (width As Double, height As Double)

매개 변수

width
Double

창의 새 너비(픽셀)입니다.The new width of the window, in pixels.

height
Double

창의 새 높이(픽셀)입니다.The new height of the window, in pixels.

예외

CanResize 속성이 false인 경우If the CanResize property is false.

예제

다음 예제에서는 크기를 조정할 수 있는 사용자 지정 컨트롤에 대해이 메서드를 구현할 수 있는 한 가지 방법을 보여 줍니다.The following example shows one possible implementation of this method for a custom control that can be resized.

/// <summary>
/// Resizes the provider to the specified height and width.
/// </summary>
/// <param name="height">The specified height.</param>
/// <param name="width">The specified width.</param>

        throw new InvalidOperationException("Operation cannot be performed.");

    if (width <= 0 | height <= 0)
        throw new InvalidOperationException("Operation cannot be performed.");

    int widthInt = (int)width;
    int heightInt = (int)height;

    // Resize should never be allowed to place a control outside the 
    // bounds of its container; the control should always be accessible 
    // using the keyboard or mouse.
    // Use the bounds of the parent window to limit the placement 
    // of the custom control.
    Size MaxSize = 
        new Size(this.customControl.formWidth - 20, 
        this.customControl.formHeight - 20);
    Size MinSize = new Size(10, 10);

    if (widthInt > MaxSize.Width)

    if (heightInt > MaxSize.Height)
        heightInt = MaxSize.Height;
    if (widthInt < MinSize.Width)
        widthInt = MinSize.Width;
    if (heightInt < MinSize.Height)
        heightInt = MinSize.Height;

설명

컨트롤에서 호출 될 때 분할 창을 지 원하는,이 메서드가 다른 인접 한 창 크기 조정의 부작용이 있을 수 있습니다.When called on a control that supports split panes, this method can have the side effect of resizing other contiguous panes.

개체 이동, 크기를 조정 하거나 결과 화면 위치가 컨테이너의 및 키보드 또는 마우스에 액세스할 수 없도록 좌표 완전히 것 회전할 수 없습니다.An object cannot be moved, resized, or rotated such that its resulting screen location would be completely outside the coordinates of its container and inaccessible to keyboard or mouse. 예를 들어, 최상위 창이 화면에서 완전히 벗어나거나 이동할 때 또는 자식 개체의 컨테이너의 뷰포트 경계 외부에 이동 됩니다.For example, when a top-level window is moved completely off-screen or a child object is moved outside the boundaries of the container's viewport. 이러한 경우 개체는 컨테이너 경계 내에 있도록 재정의 위쪽 또는 왼쪽 좌표를 사용 하 여 최대한 요청 된 화면 좌표를 가깝게 배치 됩니다.In these cases the object is placed as close to the requested screen coordinates as possible with the top or left coordinates overridden to be within the container boundaries.
