jquery start dragging object when clicked on the other with gwtquery and drag and drop - gwt

In this post the question is asked how to initiate an immediate drag operation when another object is clicked. I have the same question but in the context of gwtquery and the draggable plugin.
In the reference post the new item to be dragged is moved to be under the click point and the original mouse down event is sent on to it. Is it possible to do this in gwt?

You should be able to do something like that :
$("#myDraggable").as(Draggable).draggable();
$("#myOtherDiv").mousedown(new Function(){
#Override
public boolean f(Event e) {
//position your draggable first
//...
$("#myDraggable").trigger(e);
return false;
}
});
But the method trigger(Event e) doesn't exist yet in GQuery. I open an issue for covering that : http://code.google.com/p/gwtquery/issues/detail?id=139

How to get the gameobject- which triggered the UI.Button click function

in Unity 5- I am trying to disable a ui.button- once it is clicked. There is a list of buttons- among which- the clicked one will be disabled. But I am not sure, if it is possible to get the event triggering gameobject.
Unity Editor-
Code:
// called from ui.button clicks
public void callThisMethod(string param) {
// how to get the clicked button gameobject here
}
Just Add another event to return the button
public Button ButtonPressed(Button ThisButton)
{
return ThisButton;
}
You can add something like this to your code:
public Button yourButton;
public void yourButtonClicked(){
yourButton.interactable = false;
}
Assign your button to the Button object in inspector. Then where it says "On Click()" in the image you have above, select the script the above code is added to, and select the "yourButtonClicked()" function. That will disable the button once it is clicked.
To get your clicked button game object, you can use: EventSystem.current.currentSelectedGameObject
Pass the gameObject of the button as a parameter while your are adding event listener to the UI button.
Hope that helps:
GameObject myButtonGameObject = myButton.gameObject;
myButton.onClick.AddListener(() => {LogName(myButtonGameObject); });
public void LogName(GameObject buttonGameObject = null){
Debug.Log(myButtonGameObject);
}
Note: The given approach is useful, when you need to dynamically show the clicked buttons name, but if you know the exact button, you can make a public field for the myButton and get the name without passing any parameters.

Filter button properties set for right click

I want to give the filter button a right click function that when I right click it, it will clear all the grid criteria.
setFilterOnKeypress(false);
setFilterByCell(true);
setFilterButtonPrompt("Left click to filter, right click to clear all texts.");
Button button = new Button();
button.addClickHandler(new ClickHandler()
{
#Override
public void onClick(ClickEvent event)
{
if (event.isRightButtonDown())
{
SC.warn("right clicked");
clearCriteria();
}
}
});
setFilterButtonProperties(button);
This is not working, any ideas on why it isnt working?
Keep the functionality separate. There is no meaning of mixing two different tasks on the same button. Think from the end user's perspective.
Read more on your another post Pass a handler to filter button property that is some what asked in the same context.

Radio button change handler refreshing the page

I'm using UploadItem, RadioGroupItem and some other widgets. RadioButton is having onChangeHandler which will decide what all other components need to be displayed. I've uploaded some file using UploadItem. Then I changed the radio button selection. On changing the radio button, required widgets are getting displayed properly but whatever file I'd selected using UploadItem is going away. Fresh UploadItem widget is getting displayed. In other words page is getting refreshed.
My requirement is whenever I change radio button option, required widget should displayed along with that whatever file I had selected using UploadItem should remain same.
My Code is something like this:
UploadItem upload = new UploadItem();
RadioGroupItem radioGroup = new RadioGroupItem();
HashMap map = new HashMap();
map.put("option1","option1");
map.put("option2","option2");
radioGroup.setValueMap(map);
TextItem textbox = new TextItem();
radioGroup.addChangeHandler(new ChangeHandler(){
public void onChanged(ChangedEvent event) {
String radioValue =((String)event.getValue());
if(radioValue.equalsIgnoreCase("option2")){
textbox.show();
}else{
textbox.hide();
}
}
});
Add all created widgets to DynamicForm object using dynamicForm.setFields(all created widgets)
Changing the radio button should hide and show the textBox. But while doing that page is getting refreshed and whatever file we had selected using UploadItem is lost.
As per the documentation for hide() and show() of FormItem class, invocation of any of these methods, will cause the DynamicForm to be redrawn.
So it may cause the problem you're getting.
To overcome this issue, I would suggest you to put UploadItem in a separate DynamicForm.
fire an event on radio Selection change as
radioButton.addListener(Events.Change, new Listener<BaseEvent>() {
#Override
public void handleEvent(BaseEvent be) {
if(radioButton.getValue()){
//fire an event here for ur widget
}
}
});

Gui.Window ContextClick

Is there a way to add an Event.ContextClick to a Gui.Window in a Unity Editor script?
The following is my context menu method that I've tried calling from both OnGUI() and my window's WindowFunction (call sites denoted below as "site: no luck"). I have not been able to get the "Success" message to show up unless I'm right clicking directly in the main editor window. If I right click in any of the Gui.Windows I have created, the ContextClick event doesn't show up.
void OnStateContextMenu(){
Event evt = Event.current;
// Ignore anything but contextclicks
if(evt.type != EventType.ContextClick)return;
Debug.Log("Success");
// Add generic menu at context point
GenericMenu menu = new GenericMenu();
menu.AddItem (new GUIContent ("AddState"),false,AddState,evt.mousePosition);
menu.ShowAsContext ();
evt.Use();
}
And the call site(s):
void doWindow(int id){
// OnStateContextMenu(); //site1: no luck
GUI.DragWindow();
}
void OnGUI(){
OnStateContextMenu(); //site2: no luck here either
BeginWindows();
wndRect = GUI.Window(0,wndRect,doWindow,"StateWnd");
EndWindows();
}
Update
For reference, green area responds to right-click, red area does not. But I want it to. The right-click menu I've created has specific actions I only want visible if the mouse cursor right clicks inside one of my windows, the 'Hello' in the image. Note: Ignore the button, right click doesn't work anywhere inside that window.
This might not directly answer your question but should be able to help
You are trying to achieve a rightclick function inside your red box( as shown in picute )
I had a sort alike question a while back but it was not for a rightclick but for a mouseover
so i figured this might be able to help you
string mouseover; // first of i created a new string
if (GUI.Button (new Rect (100,100,200,200),new GUIContent("Load game", "MouseOverOnButton0") ,menutexture ))
{
//added a mousoveronbutton command to my GUIcontent
executestuff();
}
buttoncheck();
}
void buttoncheck()
{
mouseover = GUI.tooltip;
if(mouseover == "MouseOverOnButton0")
{
GUI.Box(new Rect(380,45,235,25),"Not a implemented function as of yet ");
}
}
this code made a new gui box the moment the mouse hitted the box.
If you created the hello in a seperate box you could use this
if(mouseover == hello)
{
if(rightclick == true)
{
execute the stuff you want
}
}
or something like that. Hope this helps a bit atleast
UPDATE
To obtain the rightclick event you will have to use the
if(Event.current.button == 1 && Event.current.isMouse)
You have to place this in the OnGUI to work properly
this way you first trigger the in box part, then check for a right click and execute the stuff you want.

Inserting GWT widget into a div element

I'm using a GWT library (gwt-openlayers) which allows me to create a map popup containing arbitrary HTML, similar to Google Maps. I need this HTML to contain a GWT Button widget.
I'm creating some HTML elements on-the-fly like this:
Element outerDiv = DOM.createDiv();
outerDiv.getStyle().setOverflow(Overflow.HIDDEN);
outerDiv.getStyle().setWidth(100, Unit.PCT);
outerDiv.appendChild(new HTML(mapPOI.getHtmlDetails()).getElement());
Button popupButton = new Button("View Property");
popupButton.getElement().getStyle().setFloat(com.google.gwt.dom.client.Style.Float.RIGHT);
outerDiv.appendChild(popupButton.getElement());
Then I'm getting the source HTML for these elements by calling
String src = outerDiv.toString();
and inserting this html into my map marker. Now my map marker displays the content ok, including the button. However, the button won't respond to any events! From what I can gather, this is because the buttons onAttach() method is never being called.
Is there a better way to do this?
Thanks,
Jon
~~~~EDIT~~~~
I'm now trying a new way of doing this, which seems to be the accepted method looking at other similar posts.
First I'm creating my div:
String divId = "popup-" + ref;
String innerHTML = "<div id=\"" +divId + "\"></div>";
Then I'm adding this to my map popup and displaying it (which adds it to the DOM). After the popup has been displayed, I'm getting the Element as follows and trying to wrap a HTMLPanel around it:
Element element = Document.get().getElementById(divId);
HTMLPanel popupHTML = HTMLPanel.wrap(element);
My div element is successfully retrieved. However, HTMLPanel.wrap(element); doesn't complete. The reason for this is that wrap(..) calls RootPanel.detachOnWindowClose(Widget widget), which includes the following assertions:
assert !widgetsToDetach.contains(widget) : "detachOnUnload() called twice "
+ "for the same widget";
assert !isElementChildOfWidget(widget.getElement()) : "A widget that has "
+ "an existing parent widget may not be added to the detach list";
I put some breakpoints in and it seems that the 2nd assertion is failing!
Does anybody have any idea why this might be the case? Should failing this assertion really result in a complete failure of the method (no return)?
Your first approach is good, you just need to register onClick event for your button like this:
DOM.sinkEvents(popupButton.getElement(), Event.ONCLICK);
DOM.setEventListener(popupButton.getElement(), new EventListener() {
#Override
public void onBrowserEvent(Event event) {
//implement the logic after click
}
});
I have checked this, it works 100%!
You might try something like
RootPanel.get("idOfYourMapMarker").add(popupButton);
See RootPanel.get()
Unfortunately, RootPanels are AbsolutePanels which aren't so nice for layout but could work if you just have a simple button to add. You could also try RootLayoutPanel which will give you a LayoutPanel (also not so nice when you just want things to flow). You might end up creating a container widget that does the layout for you, and adding that to the RootPanel.
SimplePanel is a DIV. Perhaps that can be used instead?
You added the element, but you have to keep the hierarchy of the actual GWT Widgets too.
I don't see a clean way to do this, but you could use something like jQuery to grab the button by and ID and add a click handler back to it that would call the original click handler.
private static native void registerEvents(String buttonId, MyClass instance)/*-{
var $ = $wnd.$;
//check click
$('#'+buttonId).live('click', function(e) {
e.preventDefault();
instance.#com.package.MyClass::handleButtonClick(Lcom/google/gwt/event/dom/client/ClickEvent;)(null);
});
}-*/;
Call this registerEvents() either in your onAttach or constructor.
I once had a similar problem. You can use the gwt-openlayer's MapWidget as follows:
private MapWidget createMapWidget() {
final MapOptions defaultMapOptions = new MapOptions();
defaultMapOptions.setDisplayProjection(DEFAULT_PROJECTION);
defaultMapOptions.setNumZoomLevels(TOTAL_ZOOM_LEVELS);
MapWidget mapWidget = new MapWidget(MAP_WIDGET_WIDTH, MAP_WIDGET_HEIGHT, defaultMapOptions);
map = mapWidget.getMap();
return mapWidget;
}
And then add it to any panel be it vertical or horizontal.
MapWidget mapWgt = createMapWidget();
VerticalPanel mainPanel = new VerticalPanel();
mainPanel.add(mapWgt);
...
... add whatever you want
...
You can finally add the created Panel(containing the MapWidget and the gwt widget) to the PopupPanel. Also, you should now be able to add handlers to the gwt button.
