tltv / gantt Goto Github PK

Hi
Now that 7.2 has been released are you going to provide a version that works with it?

Phillip

I have a small issue with gantt.scss that is not compiled with the widgets and it is missing at the end of the compilation process.
I imported it manually to my application and the addon works fine, but it would be nice to have it automatically there.
Does anybody else have this small issue?
Thanks

Hi,

I am trying to integrate the gaant-demo into our Spring-MVC application. I am having some problem with Widgetset. Can you kindly help me out. Thanks.

Here is the screenshot, which indicates the gaant-charts are not getting loaded.

Sorry for the messed up indentation in the code, Github does not seem to support ctrl+k or other shortcuts, and no tab press to indent fast. NICE!!!

What's the deal with widgetset that I always have problem with Vaadin and now with this project. I cannot find the files for widgetset and no answers on forums help. I hope you know already. Thanks a lot...

I use Vaadin 7.3.0.

I just experienced a (very) slow rendering inside Chrome (37.0.2062.122, MacOS).

That happens whenever there are many tasks in the Gantt chart (some 100 in my case).

But: only inside Chrome. If you open the page inside Safari or FF, it is much faster...

Any idea? Did you experience a similar behavior yet?

"Thank you for this add-on. Probably, I made mistake when I tried to use gantt. I compile widgetset. Add jar to my project classpath. I got no compile and runtime error .But I cannot see interface properly. Thanks in advance"

Hello

There is a possibility to export the graph in pdf or as an image to be printed, is an option that other libraries contemplated.

A greeting.

Hi,

my vaadin (7.5.10) application uses a tabsheet containing a ViewDisplay. Theme is a customized valo.

I downloaded the Gantt example but could not get it running, the result looks strange:

Do you have any hint what is breaking the gantt diagram? When opening the gantt diagram, the bars are shown for half a second on the upper right corner of its layout and then dissapear with the result above.

Cheers,
Aydin

When the gantt's height is undefined and I add a step to the gantt from a listener, the component doesn't grow. You can reproduce the bug by commenting out gantt.setHeight(500, Unit.PIXELS); line in DemoUI and add adding a step from the menu.
Can you suggest me a workaround for this issue (if exists)? Can I force height update somehow?

Thanks

Hi,

I'm using Vaadin 7.4.1 and the latest release of the Gantt add on under OS X.

When you scroll down (you can use the demo) inside Chrome, the grid will not scroll with the Gantt steps.
Inside Safari it works as expected. So there must be an issue with Chrome (41.0.2272.118 (64-bit)).

Thanks,
Markus

Hi,

Is there any way to add multiple steps on the same row - similar to the way you can split a task in MS Project?

Many thanks,

Ian

In different use cases gantt is used to display data by some categories (so each line represents a category).

In real life there might be no data for a particular category, while the line should be drawn anyway.

Now this behaviour can be unofficially simulated by

step.setStartDate( new Date() );
step.setEndDate( step.getStartDate() );

however it's a hack and looks not nice.

Could you add some official support for empty steps? Thanks

My Gantt have Start Date 01.01 and End Date 31.12. We need to have "today" selected. If I open my Gantt it will show always 01.01 and I have to scroll to the right position.

Other Gantt Diagrams are using something like a "today Bar". Something like this:
http://www.online-excel.de/excel/gragant/gantt1.gif

Thanks!!!

Unregister Gantt widget's 'onmousemove' listener when resize and move features are disabled.

Gantt has resizable function for entire steps. But I need to disable resizable for particular step.
step.setResizable(false);

Hi,

Great add-on!
I need to increase the width of resolution grid cells. I'm using the gantt chart with an hour resolution to represent tasks on a 24 hour time frame and so it would be great to increase the width of each hour cell in order to make the graph more visually pleasant...

Many thanks

This issue was closed, but we are interested to use gantt with seconds and minutes. How we can extend your addon? Which classes we have to change and add?

Hi,

is it possible to Drag something from a Table, or a Grid on a Step in the Gantt Chart? That would be so helpful.

Thanks

It will be great to have such feature

Hi, is it possible to have tree structure from left side and chart from right side for tasks? Do you have any plan to do it? Similar as for this addon https://vaadin.com/directory#addon/vaadin-gantt-diagram:vaadin
Author's response – May 24, 2014 9:34 AM
No plans on adding tree stucture like that. But utilities to delegate vertical scroll position for other components like TreeTable is a possible addition in near future.

For small steps, the "overflow : hidden" property prevents to see the caption properly. Could there be a way to either show a tooltip with a mouse over with the full description, or to choose wether or not the description should be "aligned" with the step size?

Put the component in a Tabsheet, and the whole timeline is just broken and steps are not visible at all.

Hi, I am building a resource planning instrument and I have some performance issues when I try to load 3/400 hundred steps at the same time.
Is there any plan to support lazy loading on scrolls?

With Vaadin version 7.6.2, and Gantt addon version 0.9.3 (also with 0.9.1), the following code throws javascript exception in the browser console (and the tabs will be empty)

DateTime now = new DateTime();

Gantt gantt = new Gantt();
gantt.setStartDate(now.toDate());
gantt.setEndDate(now.plusMonths(1).toDate());

Step s1 = new Step("step 1");
s1.setStartDate(now.toDate());
s1.setEndDate(now.plusDays(1).toDate());
gantt.addStep(s1);

Step s2 = new Step("step 2");
s2.setStartDate(now.plusDays(2).toDate());
s2.setEndDate(now.plusDays(3).toDate());
gantt.addStep(s2);

s2.setPredecessor(s1); //the problem goes away if this is commented out

gantt.setWidth("100%");
gantt.setHeight("500px");

TabSheet t = new TabSheet();

t.addTab(new Label("Tab 1 content"), "Tab 1");
t.addTab(gantt, "Tab 2");

setContent(t);

The exception is somewhat obfuscated, but basically it is:

SEVERE: Error sending hierarchy change eventscom.google.gwt.event.shared.UmbrellaException: Exception caught: Exception caught: Should only call onDetach when the widget is attached to the browser's document
...
Caused by: com.google.gwt.user.client.ui.AttachDetachException: Exception caught: Should only call onDetach when the widget is attached to the browser's document
...
Caused by: java.lang.IllegalStateException: Should only call onDetach when the widget is attached to the browser's document

Reproduced in 0.9.3 not in 0.9.1
While it's nice that Gantt supports custom timezones now, it's an issue it doesn't support UTC anymore.
gantt.setTimeZone( TimeZone.getTimeZone("UTC") ); will throw an exception

It is possible to avoid dependency on TimeZoneConstants.properties at all?
java has https://docs.oracle.com/javase/8/docs/api/java/util/TimeZone.html#getAvailableIDs--
we could rely always on.
Thanks.

With the latest version, I am getting a Nullpointerexception when resizing a step which was added to the gantt.
The getStep(String Uid) method actually returns a Step which is empty (getcaption, getstartdate etc always return null, even though the step was correctly added).

I have tried this programatically and with the gantt layout, and always gets the problem.

When inside demo application you replace for (int i = 0; i < 10; i++) by
for (int i = 0; i < 3; i++)

and comment out lines
gantt.addStep(step1); gantt.addStep(step2); gantt.addStep(step3); gantt.addStep(step4); gantt.addStep(stepWithSubSteps);

The design of cells is not fine (last line of cells is not drawn).
The issue is Chrome-specific.

Hello,

It would be nice to have a setData on AbstractStep object. For instance, it would help keeping a link between database object and on-screen step.

Regards

For Example in Vaadin Table is a function "setCurrentPageFirstItemId".

Would it be possible to make something similar in the gantt component so we can scroll to a date or step?

if we call removeSteps on non-empty gantt, it doesn't clear properly.
Vaadin has a lot of warnings.
In case we enable -ea JVM setting it also contains assertion error

I can't detect double click on steps. event.getDetails().isDoubleClick() is always false in Gantt click listener. Can you confirm this issue? (Or I did something wrong?)

Example:

        gantt.addClickListener(new Gantt.ClickListener() {
            @Override
            public void onGanttClick(org.tltv.gantt.Gantt.ClickEvent event) {
                if(event.getDetails().isDoubleClick()) {
                    Notification.show("Double click"); //never executed
                }
            }
        });

Thanks

The add-on by default seems not to react on touch gestures (in my case on an iPad) for "scrolling" through the diagram.

There is the touchSupported attribute and the setter (which has a typo setTouchSupporttted (3 ts)), but still I can't see where this is being called and I suppose that this is the reason.

Hello,

I need to maintain some link between my table line and the substep I create in Gantt, to use it when user clicks on it.
As there is no setData on steps, I made a subclass of substep :

public class TaskStep extends SubStep { Task task; }

With this kind of substep, Gantt is displaying without any trouble but click-event is broken : event object has no step ( event.getStep() always returns null )
I have the feeling this is something coming from uuid, so I tried to force uuid creation on my TaskStep object, but without any more success.

Regards

Hello,

I am building a resource planning app in which the steps are tasks and the lines are people (or other resources). But with this addon the user is not able to drag a step (task) from one line (person) to another.
Are you planning to add this functionality? Or ability to drag a substep from one parent to another? Or do you have any suggestion how can I implement this with the existing features?

Thanks

Hello,

Is it possible to detect if the user is holding the ctrl key when he moves the steps?
A similar feature is available in the click listener.

Thanks

SCENARIO:
Provide start/end dates in some time-zone
Set timezone of the component itself

String zone = "Europe/Amsterdam";
gantt.setTimeZone( TimeZone.getTimeZone( zone ) );
Date start = Date.from( LocalDateTime.of( 2015, 4, 1, 0, 0 ).atZone( ZoneId.of( zone ) ).toInstant());
Date end = Date.from( LocalDateTime.of( 2015, 4, 30, 0, 0 ).atZone( ZoneId.of( zone ) ).toInstant() );
gantt.setStartDate( start );
gantt.setEndDate( end );`

EXPECTED:
Show April 2015 (1-30) in gantt

ACTUALLY:
Gantt shows 31 Mar - 29 Apr
See screenshot

Extra details:
it looks like the component tries to recalculate dst offsets which might be wrong. Date passed should be just interpreted for visualizing in the component's timezone.

Your gantt chart does not seem to use the Valo theme, are you going to support this theme?

hi,

I am adding minute to timeline widget and i changed minutes interval to 5 minutes
public static final long MINUTE_INTERVAL = 5*60 * 1000;

after scrolling the interval display wrong values

I cannot get the steps to move or to be resized in chrome, while it works perfectly in IE11.
Chrome is latest version.

Currently timezone offset with daylight saving time is detected always from the current date. Make it easier to override this date.

SCENARIO:
For a substep in demo page
subStep1.setIdentifier( 123L );

Click on that substep on screen

No issues, just some custom value is available to retrieve from the SubStep

Gantt.ClickListener is called, but event.getStep() is null

BUILD FAILURE

gant.addMoveListener(new Gantt.MoveListener() {
   @Override
   public void onGanttMove(MoveEvent event) {
   Step step = (Step) event.getStep();
   }
}

I get the step's last position; but I need starting point before moved. Is it possible to support this function?

I would like to use the gnatt chart to show jobs that are run during a 24 hour period.
Some jobs only take a few seconds where others can take a few hours.

I could also see the gantt chart used to show meetings in day.

Hi,

first of all: very nice add-on!

Is it possible to move steps vertically by dragging them?

Thanks,
Markus

Would be nice to detect which mousebutton was clicked in the Clickevent so we can implement for example a contextmenu for step editing.

This issue wasn't reproducible in 0.9.1 but started to occur in 0.9.3

Consider an example of following code:

    private static final Step step = new Step();
    static {
        SubStep subStep = new SubStep();
        Date start = new Date();
        subStep.setStartDate( start );

        Date end = new Date();
        end.setDate( start.getDate() + 1 );

        subStep.setEndDate( end );
        subStep.setStyleName( "APPSubStep SomeStyle" );

        step.setStyleName( "APPStep" );
        step.addSubStep( subStep );
    }

some UI method:

gantt.removeSteps();
gantt.addStep( step );
gantt.removeSteps();
gantt.addStep( step );

After these actions, gantt contains the step with styling broken (no styling enforced by 'APPStep APPSubStep SomeStyle' work).

In 0.9.1 it worked.

(actually after this remove/add we faced even more problems than styling, however they were harder to reproduce. I hope fixing the reason of styling issue might fix the other problems).

Since migrating to Vaadin 7.7.0, addon is not working anymore. It complains about missing libraries :

java.lang.NoClassDefFoundError: com/google/gwt/i18n/client/constants/TimeZoneConstants
java.lang.NoClassDefFoundError: com/google/gwt/i18n/shared/Localizable

Regards

I work with a demo. Added to the VerticalLayout components. After removing any changes appear to have been below components my not drawn layer (including Gantt).

P.S. such problem occurs only when the chart displayed Predecessors line

In Windows10 Home, IE11.20.10586.0 when we select odd amount of days for Gantt, the last day is missed.
See screenshot

(note : bars for the whole period are also drawn in wrong way for such periods)

If we try to add gantt using Reindeer theme, the component does not work on screen right.
