I have a ListBox control defined within MainWindow and its IsManipulationEnabled property is set to true. I have the manipulation events (OnManipulationStarting, OnManipulationInertiaStarting and OnManipulationDelta) defined in the MainWindow. The goal here is to achieve a translation on the Listbox control, more like a flip functionality.
However, these events are never raised. I am assuming that the selection events are in turn gobbling these events. When I use itemscontrol instead, it works fine. But the problem in using itemscontrol is that I do not get a selection state. Another option would be to work on raw touch, but manipulations are way easier.
Why do the Manipulation events not fire on Listbox?
Thanks in advance!
The default template for an ItemsControl doesn't contain a ScrollViewer but the ListBox does. The ScrollViewer handles those events when the PanningMode is something other than None. By default a ScrollViewer binds several of its properties (like PanningMode) to that of its templated parent. Try setting the attached ScrollViewer.PanningMode property to None on the ListBox.
<ListBox ScrollViewer.PanningMode="None" />

what could be the best way to control events in RecyclerView items? That is, if we are going to change the display of the Recycler View items, or if we are going to test an event on them at all, what would be the best way?
I mean, to control these changes on each item in the onBindViewHolder() method, or in the MyViewHolder class, if the latter is more appropriate, then how do we calculate the first position?
Because Default -1 comes first and this issue causes it to crash sometimes.
Thank you if you have a better experience in this field
If you want to perform the event automatically (not from user behaviour), then you must do it within onBindViewHolder().
If you want to perform an event based on the user behaviour (like click, drag, etc.), then you can do it within the onBindViewHolder() or MyViewHolder.
I have a managed action with returns bool when a button is pressed.
Depending on if true / false is returned I want to be able to change the properties of controls on the dialog. Not limited to just the text value.
Is this possible, for example the visibility, etc?
It is possible, however you will have to make sure there is a set-property control event (after your managed code custom action do-event) that touches a property related to anything you want the UI to update. If you change a property value within the managed code, or via the wrapper InstallShield provides, the Windows Installer UI doesn't track the change and update in response.
So, for example, you could wire your return value to the property RETURNVALUE, and then add a control event that sets better named properties like MYCONTROLTEXT or SHOWMYCONTROL; the control or its conditions would be wired to those better named properties.
I am using a file download control and I would like to set the value of the "allowDelete" property dynamically depending on whether the document is in edit or read mode. However, this
property is computed onload of the page. I tried calling the function "setAllowDelete(boolean)" on the onclick event of a button or the "beforeRenderResponse" event of a custom control and a partial or full update to change the value of the property, but it didn't change.
Do you know if there is a way to do this?
Thanks a lot in advance!
I have encountered the same problem. There are two options to workaround it.
1) To use two controls, one with deletion enabled, the other with deletion disabled, and use rendered properties according to edit state (or user role).
2) Render download controls by your own, as data table or repeat. However, this solution has its own problems, too.
Have you tried just calculating the property like this?
<xp:fileDownload .... >
<xp:this.allowDelete><![CDATA[${javascript:
return document.isEditable()}]]>
</xp:this.allowDelete>
</xp:fileDownload>
I have a repeat that has buttons embedded in it. The repeat is in a panel. When the user clicks a button the button should hide/show (I partial refresh the panel). The repeat is tied to a Domino view and I see the other values that I from that view get updated in the repeat, so, it does not seem like a view index issue (I refresh the view index in my code.)
If I use context.reloadPage() in my button onclick code then the buttons will hide/show like they should, but, that seems like I am using a sledge hammer! Any suggestions on how to get the buttons to recompute the visible property when the panel that holds the repeat is rendered? Another strange thing is that the visible property gets computed three times whenever I refresh the panel that holds the repeat.
thanks, Howard
I think your looking for
getComponent("<id>").setRendered(true / false);
Hi For Repeat control's entry is used to make our head hard. Because handling the entry by SSJS, we can get the value and set the value. But rendering part, id of the repeating component are same for all. So if we try to give reder as false. It hides all of our repeating component.
Try to use the following., [Put this in button onclick, and see the value of below]
var entryValue= getComponent("repeat1").getChildren().get(0).getValue()
getComponent("inputText1").setValue(entryValue)
But in client side we can easily handle. Because the id of the DOM object is unique for all repeating component.
var id1="view:_id1:repeat2:"+'2'+":button1"
document.getElementById(id1).style.display="none"
This will hide the third entry of your repeat control component.
Please see the post, You may get better idea
Found a solution. My original solution was getting values from the repeat rows (using the collection object, which was a viewentrycollection and using getColumnValues) to compute the rendered property for the buttons.
Instead, I created a viewScope variable (a Vector) that holds the state of the buttons (which set of buttons to show). This gets populated in the beforePageLoad event of the page.
The button onclick code updates this viewScope variable after performing its processing. All works very nice now. I guess it was something in the JSF lifecycle that kept the buttons from being properly updated. Using the viewScope variable works fine.
With addition to what Ramkumar said, you can use the index variable in the repeat control to identify each and every occurrences inside the repeat control. You will get more idea, if you inspect with element from firefox[You might need firebug]. Usually the field mentioned inside a repeat control itself can be considered as an array
I have a Glade GUI description file with a GtkTreeView in a GtkHBox in a window; and there's a handler for the row_activated signal. Now, Glade has automatically set the "events" property (inherited from GtkWidget) of that treeview to some value (GDK_POINTER_MOTION_MASK | GDK_POINTER_MOTION_HINT_MASK | GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK). And there are two strange things with this:
removing the pre-set value (so that the property is empty) doesn't seem to break the application (at least not with the old GTK 2.10 I have atm).
in fact, an annoying bug I has seen before (where the treeview items would not correctly react to expand or collapse clicks) is now gone!
I have yet to test this with a newer GTK version, but the question is already there: exactly what is the purpose for this events property? And why does Glade automatically and unnecessarily set it to some value? Does this have some side effects I'm not aware of?
It's a bug in glade, it always sets the event property of widgets it create. It has no notion of the default value of a property so it always sets it.
Doesn't this mask indicate the events you're willing to receive? In this case, you'll probably want to receive notification that the user has clicked or double-clicked an item in the GtkTreeView, and you'll want to register callbacks to handle these events.
me.yahoo.com/a/kUQ7zeQ: but even if I set the property to an empty string as mentioned, the row_activated handler is still called when I double-click on a row (or press Enter or Space). So the treeview still gets events...
