Hello everyone, i’m new with this framework and i’m trying to make a simple layout example with a few add-ons, the thing is that i don´t know if i can add more than one add-on to the app, i want to use treetable, jfreechartwraper and passwordfield, if it’s possible can sombody help me with that.
The other problem than i’m having, maybe becouse i don´t know how to add the add-ons, is that i want to show a jfreechart in the layout but nothin happens, i added it into a panel, i don´t know if it’s possible to add it into a panel.
The main layout consists of one horizontal split with the treetable as first component and another horizontal split as second component, in the second component of the second split i want to display the jfreechart.
This is the example code i made for the chart.
public class GanttPanel extends Panel implements ChangeListener{
JScrollBar scroller;
SlidingGanttCategoryDataset dataset;
public GanttPanel(){
//super(new BorderLayout());
dataset = new SlidingGanttCategoryDataset(createDataset(), 0, 15);
JFreeChart jfreechart = crearGrafica(dataset);
ChartPanel chartpanel = new ChartPanel(jfreechart);
chartpanel.setPreferredSize(new Dimension(700, 450));
scroller = new JScrollBar(1, 0, 15, 0, 50);
this.addComponent((Component) chartpanel);
scroller.getModel().addChangeListener(this);
//JPanel jpanel = new JPanel(new BorderLayout());
this.addComponent((Component) scroller);
//jpanel.setBorder(BorderFactory.createEmptyBorder(66, 2, 2, 2));
//add(jpanel, "East");
}
public static GanttCategoryDataset createDataset(){
TaskSeries tskProgramado = new TaskSeries("Programada");
TaskSeries tskActual = new TaskSeries("Actual");
Day day = new Day();
Day day1 = new Day();
for(int i = 0; i < 50; i++)
{
int j = (int)(Math.random() * 10D) + 1;
for(int k = 0; k < j; k++)
day1 = (Day)day1.next();
tskProgramado.add(new Task("Task " + i, new Date(day.getMiddleMillisecond()), new Date(day1.getMiddleMillisecond())));
tskActual.add(new Task("Task " + i, new Date(day.getMiddleMillisecond()), new Date(day1.getMiddleMillisecond())));
day = (Day)day1.next();
day1 = (Day)day1.next();
}
TaskSeriesCollection taskseriescollection = new TaskSeriesCollection();
taskseriescollection.add(tskProgramado);
taskseriescollection.add(tskActual);
return taskseriescollection;
}
private static JFreeChart crearGrafica(SlidingGanttCategoryDataset slidingganttcategorydataset){
JFreeChart jfreechart = ChartFactory.createGanttChart("NOMBRE PROYECTO", "ACTIVIDAD", "FECHA", slidingganttcategorydataset, true, true, false);
CategoryPlot categoryplot = (CategoryPlot)jfreechart.getPlot();
Hour hour = new Hour(1, 14, 5, 2008);
for(int i = 0; i < 12; i++)
{
IntervalMarker intervalmarker = new IntervalMarker(hour.getFirstMillisecond(), hour.getLastMillisecond(), Color.lightGray);
categoryplot.addRangeMarker(intervalmarker, Layer.BACKGROUND);
hour = (Hour)hour.next().next();
}
categoryplot.getDomainAxis().setMaximumCategoryLabelWidthRatio(10F);
DateAxis dateaxis = (DateAxis)categoryplot.getRangeAxis();
dateaxis.setRange(DatasetUtilities.findRangeBounds(slidingganttcategorydataset.getUnderlyingDataset(), true));
GanttRenderer ganttrenderer = (GanttRenderer)categoryplot.getRenderer();
ganttrenderer.setDrawBarOutline(false);
ganttrenderer.setShadowVisible(false);
return jfreechart;
}
public void stateChanged(ChangeEvent e) {
dataset.setFirstCategoryIndex(scroller.getValue()); //scroll
}
}
This is how i add it to the layout, i’m not using the jfreechart add-on.
secondsplit.setSecondComponent(pnlGantt);
Thanks to everybody.
Hope my english is not that bad
