JXA和OmniGraffle

Question

我不知道如何将以下AppleScript转换为JXA ( Mac下的自动化JavaScript)：

tell application id "com.omnigroup.OmniGraffle6"
    tell canvas of front window
        make new line at end of graphics with properties {point list:L, draws shadow:false}
    end tell
end tell

下面是我尝试过的方法，但在执行最后一行时失败，并显示错误"AppleEvent handler failed“：

app = Application('OmniGraffle')

pt1 = app.Point({x:1,y:2})
pt2 = app.Point({x:1,y:2})

L = []
L.push(pt1)
L.push(pt2)

line = app.Line({pointList:L})

app.documents[0].canvases[0].lines.push(line)

有人能帮上忙吗？

谢谢，Aurelien

Answer 1

图形对象(线条、形状等)包含在图形集合中。因此，您必须将最后一行更改为

app.documents[0].canvases[0].graphics.push(line)

Answer 2

还有一个等价但更完整的例子：

(function () {
    'use strict';

    var og = Application("OmniGraffle"),
        ds = og.documents,
        d = ds.length ? ds[0] : null,
        cnvs = d ? d.canvases : [],
        cnv = cnvs.length ? cnvs[0] : null,
        gs = cnv ? cnv.graphics : null;

    return gs ? (
        gs.push(
            og.Line({
                pointList: [[72, 216], [216, 72]],
                drawsShadow: true,
                thickness: 3,
                lineType: 'orthogonal',
                strokeColor: [1.0, 0.0, 0.0],
                headType: "FilledArrow"
            })
        )
    ) : null;

})();
