We would like to implement an interactive weekly scheduler. We are using Highcharts extensively on the rest of our project and was hoping to use Highcharts for this purpose rather than create our own custom built interface.
Attached is a picture of the intended user interface. The idea is that a user with editing rights will be able to click and drag anywhere in the pane to turn the scheduled block on or off, depending on the current state of the block. We would like to use 5 minute intervals (ie 288 slots per day).
Is there any way in which Highcharts will be able to support this functionality?

I am creating a Google Data Studio dashboard that is supposed to be on a constant display on a screen in my office. The dashboard runs on a Raspberry Pi which currently boots into fullscreen Chromium with the dashboard as starting page and refreshes the page every 60 minutes. Unfortunately the URL only opens the dashboard with the control tab on the top. Is there any way to include a parameter in the URL that automatically opens the "Present" mode such that there are no controls on top and with the automatic sheet change every 60 seconds?
Use a click automation tool like "Pullover's Macro Creator" to automate the presentation mode button click.
I want to know the event in blocks section using which the entered text value can be obtained without a form submission through button.
Let's say user inputs text in mobile phone through keyboard and presses enter. In this case I want some event to trigger and get the value that user entered.
There are 2 events available like lostfocus and gotfocus.
Will these work? Or is there any other good approach for getting text value on pressing enter?
Unfortunately there is no such event like OnEnterPressed available in MIT App Inventor and the events LostFocus and GotFocus will not work in this case.
What you currently can do is
use a button and use the Button.Click event, or
create your own custom keyboard, see also this example
Currently there is a limitation for App Inventor extensions, which only can be used for non-visible components. Later as soon as also visible components are doable, then you could write your own textbox extension and add an event yourself.
Edit concerning the new question in the comments about different screens:
Use different screens wisely
Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed...
You can insert a Clock component that monitors the TextBox1.Text. When it triggers, it checks if the TextBox1.Text has changed and saves it to a variable. When it triggers again, it compares the variable with TextBox1.Text. After the user finishes typing, the variable and TextBox1.Text will be equal and then you can trigger the event like you eanted when the user pressed Enter.
Hope this helps!
Developing Smart Devices in Genexus. I am using the Load Event to load some hundreds of records (returned by a 3rd party webService) into the Grid (some rows might have different layouts).
When the user hits the search button, a ProgressIndicator is immediately shown (during the procedure execution). When the procedure ends (data retrieved), the ProgressIndicator disappears but it may take an additional 4-5 seconds for the Grid to show the fresh data.
This causes the user to think that there was a problem with the search. Then, unexpectedly, the grid refreshes.
Is it possible to, somehow, show a ProgressIndication during the Load or Refresh Events?
Or do you have any suggestions to prevent this behavior?
The main issue is that Refresh and Load events are "server" events in SD architecture so you don't have access to the device's APIs or resources like the Progress Indicator.
We had the same requirement in iOS and what we did was using the GXRefresh event.
Event 'gxrefresh'
Composite
//Your code. Example: ProgressIndicator.Hide()
EndComposite
EndEvent
Gxrefresh is a Local event that is executed after the Refresh and Load. Is a hidden event that helped us accomplish this. (This is not an official event and it can be taken out in any version of GeneXus)
So the solution is:
Start a Progress Indicator on the ClientStart event of that Panel.
Hide the Progress Indicator on the 'gxrefresh' event of that panel.
Note: Remember that in order to use the gxrefresh event you will need to add a hidden button named 'gxrefresh'. You can hide that button as you will not need it in the UI (we put it Visible=false on the application bar).
If that solution for any reason is not possible (for example the gxrefresh event is deprecated or you are developing for Android) I can think of a second WA that is not elegant at all but should work.
Start the Progress Indicator in the Client Start Event of the panel
Put a hidden variable with control type SD Chronometer.
Set the timer for 6 seconds
Stop the Progress Indicator on the Tick event of the SD Chronometer and stop the Chronometer so the Tick event is not executed any more.
These are the two options I can think of.
Maybe there is an easier way but I haven't heard of it. A Grid.DidLoad event would be great for this scenario. For sure we will have this soon or some other solution for this problem.

In android, there is a function call Toast and it show instantly without involve in time. I tried to use Status in RIM but it must run in the invokeLater and cannot set the time less than 1 second. So it cannot display instantly.
Any other built in that same with Toast or Status?
No there is not afaik. Toast was "invented" in a way by Android.
Previous OS's have used popup boxes with confirmation buttons. A Toast is almost like a popup box with a timer attached to it.
Of course, #Signare gives the common replacement correctly for what you would "normally" do on BlackBerry. Dialog.alert(String)
If you want something more "Androidy", this is something we want to implement at Cobi, but have not gotten around to yet due to time constraints working on client work.
There are 2 unique aspects to a Toast compared to the "old" way of doing things:
the popup only shows for a short time
the popup does not block the user from interacting with the background screen at all
To create the popup screen, look at the PopupScreen class - and you pass in a layout manager of your own that will be displayed.
You could start a timer when the screen is shown (we have not implemented this yet) and that could close the screen for you.
As far as not blocking the user - this is the major difference - and I do not know if it can be done if you use the PopupScreen class. Perhaps if your PopupScreen passes all keypresses through to the underlying screen, this may be possible.
In some of our apps, we have a custom field, defined in our base MainScreen subclass, that can be positioned over the rest of the fields on the screen. This allows the user to continue interacting with the screen while the field is displayed. I cannot share that code at the moment here.
since i am developing a project on Exchange trade fund and in its first page layout
we are developing labels and we want that on clicking on that labels page related to that
label may appear on another vertical field manager on the same screen and on that very screen i want page control so that on tracking wheel we may obtain the next page following that page
thanking you
You can capture trackwheel (e.g. trackwheelClick, trackwheelRoll) events and update the textual contents of the page appropriately.
Just implement these functions as a part of your mainscreen class.
