在Gojs中,是否可以提供自定义图标?就我而言,我想使用SVG / PNG图像作为PanelExpanderButton图标。
go.GraphObject.defineBuilder("PanelExpanderButton", function(args) {
var eltname = /** @type {string} */ (go.GraphObject.takeBuilderArgument(args, "COLLAPSIBLE"));
var button = /** @type {Panel} */ (
$("Button",
{ // set these values for the visible binding conversion
"_buttonExpandedFigure": $(go.Picture, {
// desiredSize: new go.Size(10, 10),
source: "assets/images/expand.png"
},
),
"_buttonCollapsedFigure": $(go.Picture, {
// desiredSize: new go.Size(10, 10),
source: "assets/images/collapse.png"
},
)
},
$(go.Picture, { source: "assets/images/expand.png", desiredSize: new go.Size(10, 10) },
new go.Binding("figure", "visible", function(vis) { return vis ? button["_buttonExpandedFigure"] : button["_buttonCollapsedFigure"]; })
.ofObject(eltname)
)
)
);
var border = button.findObject("ButtonBorder");
if (border instanceof go.Shape) {
border.stroke = null;
border.fill = "transparent";
}
button.click = function(e, button) {
var diagram = button.diagram;
if (diagram === null) return;
if (diagram.isReadOnly) return;
var elt = button.findTemplateBinder();
if (elt === null) elt = button.part;
if (elt !== null) {
var pan = elt.findObject(eltname);
if (pan !== null) {
diagram.startTransaction('Collapse/Expand Panel');
pan.visible = !pan.visible;
diagram.commitTransaction('Collapse/Expand Panel');
}
}
}
return button;
});
当面板展开/折叠时,我无法更改图标
我在尝试使用图片,但没有成功
编码愉快!

“图形”必须是Shape.defineFigureGenerator定义的名称之一,包括库中预定义的所有图形名称。因此,您不能以这种方式使用图片。
但是您可以复制和修改https://gojs.net/latest/extensions/Buttons.js中提供的“ PanelExpanderButton”的定义。这样,您可以调整其大小并为其状态提供任意形状。如果您想使用SVG,请注意特定于平台的限制:https://gojs.net/latest/intro/pictures.html#UsingSVGAsPictureSource
