i have what appears to be a non-standard use case: a kids game for which i'd like for an item to be deposited in a container as soon as the item is dragged over the container, without waiting for a drop event.
i'm thinking of subscribing to the over event:
dragulaService.over.subscribe((value) => {
and then calling the end api
drake.end()
but i can't find it on the dragulaService object... any suggestions? thank you!

I am developing a WinUI3 app containing a NavigationView. The NV uses an observable collection to populate the NavigationViewItems.
The app must support expanding and collapsing NavigationViewItems programmatically. The only way I know of to do that is to set NavigationViewItem.IsExpanded = true. And the only way I know of to get the NavigationViewItem is through NavigationView.ContainerFromMenuItem().
The trouble is, ContainerFromMenuItem always returns null except when it is executed from a button event handler (such as a Click handler). The app must perform expand/collapse without user input.
For example, I have a button that launches a Click event with this code, which works just fine to toggle an NVItem:
Category selectedItem = (Category)navview.SelectedItem;
int idx1 = Categories.IndexOf(selectedItem);
var container = (NavigationViewItem)NavView.ContainerFromMenuItem(Categories[idx1]);
if (container != null)
{
container.IsExpanded = !container.IsExpanded;
}
However, that same code, when executed during app startup, such as in the MainWindow constructor after some test items are created, or in Attach(), always results in container being null.
So what am I doing wrong?
This question is somewhat similar to UWP: NavigationView.MenuItems results empty if populated programmatically but the answer to that one only deals with in-event use of ContainerFromMenuItem().
Thanks very much for any assistance on this.
I was using Event aggregate publish method to update view from another view. when I created publish and subscribe data was able to get in view model , but that is not updating in view with assigned variables. If I use JavaScript to fill value it's working but not able to trigger validate controller.
Expected result is:
From the subscribe method I have to fill the view values.
After that it should trigger validate on value changes.
In below gist run I have two view and view-model. One is registration-form and second one is data-form. In data-form I have table with data, on click of each row I am publishing one event with selected row data, and this published event I was subscribing in side of registration-form view-modal. For more details look into below gist run.
Gist run: https://gist.run/?id=8416e8ca1b9b5ff318b79ec94fd3220c
Two possible solutions: (to your "undefined" alert)
Change alert(this.email); to alert(myself.email);
Use the thick arrow syntax for the subscribe function. Change:
this.ea.subscribe('MyrowData', function(obj){
to
this.ea.subscribe('MyrowData', obj => {
This syntax allows the new function to preserve the context/scope of the parent, which means that this.email will still be accessible.
Another suggestion:
You could simplify your data-form.js function as follows:
Change:
this.eventAggregator.publish('MyrowData', this.items[this.items.indexOf(item)]);
to:
this.eventAggregator.publish('MyrowData', item);
This will work because you've already provided item in your function call click.delegate="PopulateData(item, $event)".
In fact, you could even delete $event and event from the two PopulateData definitions (in data-form.js and data-form.html).
When I implement these suggestions, your data is also validated correctly.
My resource list is a list of users for my scheduler. I would like to show a tooltip when hovering over them that displays user specific information. I can do this easily for events with the eventMouseover but can someone help me do this for resources?
I have all of the user info I just do not know how to make the tooltip appear.
I solved this using the resourceRender function http://fullcalendar.io/docs/resource_rendering/resourceRender/
function resourceRenderCallback(resourceObj, labelTds, bodyTds){
var title = 'Name: ' + resourceObj.title;
labelTds.attr('title', title);
}
From here you can add whatever you desire to title. Another possibility is
labelTds.on('hover', function(){console.log('hover');});
which would allow any jquery event to be triggered for the resource
I am trying to automate IE11 notification bar ( while downloading file) using Rautomation. Using MSUIA adapter I am able to catch the the save button. But I want to use Save As to supply the file location and name. But I cannot do that.
When seeing with UIspy I see that there is a splitbutton with name "Save". This splitbutton has another child splitbutton with name "" ( which is basically the down arrow) - I am not able to get to this control.
iemainwindow_local = RAutomation::Window.new(:class=>"IEFrame" , :adapter => :ms_uia )
ienotificationbar_frame = iemainwindow_local.child(:class=>"Frame Notification Bar")
ienotificationbar = ienotificationbar_frame.child(:class=>"DirectUIHWND")
if ienotificationbar.exists?
ienotificationbar.activate
sleep 1
mycontrol = ienotificationbar.control(:value =>"Save")
mycontrol2= mycontrol.control(:children_only => true)
mycontrol2.exist?
mycontrol.click
end
Getting error at this line mycontrol2= mycontrol.control(:children_only => true)
undefined method `control' for #<RAutomation::Adapter::MsUia::Control:0x4108e60>
Any idea how to get over this block?
I understand that there should be a menu and menuitems associated with the splitButton and when I click on down arrow besides Save, at UISpy I see that menu/ menu item is getting created directly under Desktop window ( though the processID is same ) - how to catch the menuitem Save as?
The Problem
Unfortunately, the :ms_uia adapter for RAutomation is not able to do this in its current form. I know this because I have written a lot of the UIA adapter for it :) The problem is that the current API doesn't allow you to really walk the tree like that (as you found out) because the Control class doesn't have a #control method. If the "Save" button had a native window handle, you'd be able to do this:
ieframe = RAutomation::Window.new(class: 'IEFrame')
save = RAutomation::Window.new(hwnd: ieframe.control(value: 'Save').hwnd)
save.control(index: 0)
Since it does not, unfortunately there isn't a reliable way to get down to it that I am aware of since it doesn't have any identifying properties about it (other than being a child of the "Save" button).
Alternative
I've written another gem called uia, which acts as a low-level wrapper around UI Automation and allows you to work more closely with UI Automation and interact with it how you see it within tools like UI Spy. Eventually, I will use this gem in RAutomation but have not had the time yet. To get down to the "Save As..." split button control in your circumstance, you can do this:
ieframe = UIA.find_element(title: /Thanks for downloading/)
save_as = ieframe.find(name: 'Save').find(control_type: :split_button)
save_as.as(:invoke).invoke
The save_as.as(:invoke) will treat the found "Save As" Element as something that implements the Invoke pattern, and then you can call the #invoke method to get the menu to pop.
Hope this helps!
in my program I have 2 'screen', in the first there is a list and if I press an item I go to the second screen… and in the second screen there is a button to return in the first…
when I return in the fist I get this warning
WARN][Ext.Component#constructor] Registering a component with a id (`usernamelabel`)
which has already been used. Please ensure the existing
component has been destroyed (`Ext.Component#destroy()`.
in the controller i tried something like this:
itemUp: function (dataview, index, target, record, e, Opst ) {
Ext.Viewport.animateActiveItem({xtype: 'mytabpanel'},{ type: 'flip' );
var store = Ext.getStore('Customers');
store.clearFilter();
Ext.destroy(this.searchField);
Ext.destroy(this.clientsList);
}
but doesn't work.. how to destroy an entire 'screen'?
PS: if I run the program in iOS or android devices I see ever the same "theme"…
how to specialise the theme? (on my win phone 7.8 doens't works.. is normal?)
thanks a lot!!!
It's because you harcoded id: usernamelabel, so when you initiate it the second time, you'll get above warning message. You'll be safe if you use itemId
