有一个问题:
public var panelProcess:VBox;
panelProcess = new VBox();
panelProcess.addChild(sf);
panelProcess.setStyle("horizontalAlign","center");
panelProcess.setStyle("verticalAlign","center");
panelProcess.setStyle("backgroundcolor",0xe9e9e9);
panelProcess.buttonMode = true;
panelProcess.useHandCursor = true;
panelProcess.toolTip = "Click to cancel request";
PopUpManager.addPopUp(panelProcess, apc, true); //apc is DisplayObject
PopUpManager.centerPopUp(panelProcess);
单击 ChartItem 时,我在图表顶部创建了一个 PopUpManager,但我发现图表的 Datatip 比 PopUpManager 更重要。当鼠标悬停事件在 ChartItem 上时,Datatip 显示,然后 PopUpManager 被创建,但 datatip 并没有消失,它在 PopUpManager 之上,我该怎么办?帮助!
