How to make specific sides of rectangle to be resizable?

本文关键字：调整 何使矩      更新时间：2023-09-26

我想在Graphiti中调整矩形的几条或单侧的大小。如果有人有任何想法，请帮帮我。

提前谢谢。

在1.0.0版本中，您可以覆盖Figure.showResizeHandles方法。示例参见HorizontalBus图

/**
 * @method
 * Callback to update the visibility of the resize handles
 * 
 * @param {graphiti.Canvas} canvas
 * @param {graphiti.ResizeHandle} resizeHandle1 topLeft resize handle
 * @param {graphiti.ResizeHandle} resizeHandle2 topCenter resize handle
 * @param {graphiti.ResizeHandle} resizeHandle3 topRight resize handle
 * @param {graphiti.ResizeHandle} resizeHandle4 rightMiddle resize handle
 * @param {graphiti.ResizeHandle} resizeHandle5 bottomRight resize handle
 * @param {graphiti.ResizeHandle} resizeHandle6 bottomCenter resize handle
 * @param {graphiti.ResizeHandle} resizeHandle7 bottomLeft resize handle
 * @param {graphiti.ResizeHandle} resizeHandle8 leftMiddle resize handle
 * @template
 */
 showResizeHandles: function(canvas, resizeHandle1, resizeHandle2, resizeHandle3, resizeHandle4, resizeHandle5, resizeHandle6, resizeHandle7, resizeHandle8)
 {
    resizeHandle4.setDimension(resizeHandle4.getWidth(), this.getHeight());
    resizeHandle8.setDimension(resizeHandle4.getWidth(), this.getHeight());
    this._super(canvas, resizeHandle1, resizeHandle2, resizeHandle3, resizeHandle4, resizeHandle5, resizeHandle6, resizeHandle7, resizeHandle8);
    resizeHandle1.hide();
    resizeHandle2.hide();
    resizeHandle3.hide();
    resizeHandle5.hide();
    resizeHandle6.hide();
    resizeHandle7.hide();
 },

这将在右侧和左侧创建两个具有父对象全高的调整大小控制柄图

1.0.0版本将于9月17日发布
