Post subject: | getLastActiveChart problem |
Hi, In my plugin code, I'd like to determine the current (active) chart. For context variable of type IPluginContext I call getLastActiveChart(). As a result I get the active tab chart object - this is OK. But when this code is run just after starting the platform (without clicking on any tab) - accessing the chart object is not possible - it ends with IllegalStateException (until I click on any tab). Best regards, Marcin |

The workaround for this case is to set programmaticaly one of the existing tabs as active. private IChart getActiveChart() { IChart ret = context.getLastActiveChart(); if (!ret.isAlive()) { // we've got non-accessible chart object Set<IChart> currentCharts=context.getCharts(); if ((currentCharts==null)||(currentCharts.isEmpty())) return null; IChart chart = currentCharts.iterator().next(); chart.setFocus(); // switch to this tab return chart; } return ret; } |
