Microsoft Excel中可能有两种控件。有旧版表单控件和ActiveX控件。创建遗留表单控件是可能的。 ActiveX控件要复杂得多。

旧版表单控件存储在每张VML图纸中。 Apache poi已经具有XSSFVMLDrawing类，因为单元格注释也部分存储在VML绘图中。但是，在apache poi中，该类通常不完整，并且设置了其方法的可访问性，因此该类无法轻松扩展。似乎apache poi开发人员经常明确希望阻止其类的扩展。

对于旧版Checkbox控件，我们需要一个复选框形状类型，然后在此VML绘图中需要复选框形状。

以下代码创建两个旧的复选框。

方法XSSFVMLDrawing getVMLDrawing(XSSFSheet sheet)从图纸中获取VML绘图，或者如果尚不存在，则创建一个新的绘图。

方法void addCheckboxShapetype(XSSFVMLDrawing drawing)向图形添加了一个新的复选框形状类型。

方法void addCheckbox(XSSFVMLDrawing drawing,int col1,int dx1,int row1,int dy1,int col2,int dx2,int row2,int dy2,String label,boolean checked)向具有给定位置和标签的图形添加一个新的复选框形状，并具有一个Checked元素，该元素在选中时包含1，在未选中时包含0。

请注意，对于上述解决方案，如FAQ N10025中所述，需要所有模式ooxml-schemas-1.4.jar（旧版本的较低版本）的完整jar。
