Waterfalls in charge of javascript in the qml file

Cascades does support javascript in the qml file? If Yes please let me know how to use js in qml file.

Something tells me that you could not start by checking all the introductory documents. :-)

https://developer.BlackBerry.com/Cascades/documentation/dev/index.html should help you get started, especially the section he titled "JavaScript in QML.

Anyone else unable to edit QML files with the new Cascades Beta 4?

I can edit in text mode, but the default editor is suspended the IDE when an existing QML file is changed.

Yes I can. I don't have the QML preview because I use Win 8 64 bit, but the QML perspective opens.

Have you tried a new clean rather than installing on Beta 3 installation?

the false signal is not received by OtherQml.qml so the functions are not able to run one time or as in this example, the background to red

Restrict the qml file picker for formatting

According to https://developer.blackberry.com/cascades/reference/bb__cascades__pickers__filepicker.html#property-, you can define a filter in qml.

Here is the code I try:
```
FilePicker {
      id: filePicker
      type: FileType.Other
      filter: {"*.pem"}
      directories: [ "/accounts/1000/shared/" ]
 }
```
I also tried "pem", but without success. The debug output indicates that the filter is set, but it does not show the files with this extension.

Any tips?

This code below works, but should be a specified exact directory (such as various, documents, etc.), you can't store files directly in the common dir.
```
attachedObjects: [
        FilePicker {
            id: filePicker
            type: FileType.Other
            title: "Select files"
            directories: [ "/accounts/1000/shared/misc" ]
            filter: [ "*.pem" ]
            onFileSelected: {
                console.log("FileSelected signal received : " + selectedFiles);
            }
        }
    ]
```

Is it possible to include a qml file in another file?

Hello

I am creating a list as an example of stamp,

However, all these QML files fall within a records

what I'm trying to do is to create various QML files, and some of these files are shared within other files.

for example: I break the code of stampcollectorapp qml,.
```
                    // Second level item see the component in StampItem.qml.
                    ListItemComponent {
                        type: "item"
                        StampItem {
                        }
                    }
```
The line to [StampItem] looking for another QML file,

If I define StampItem in other current folder, how to write and thank you?
```
                    // Second level item see the component in StampItem.qml.
                    ListItemComponent {
                        type: "item"
                        myqmlpath???/StampItem {
                        }
                    }
```
I think that you must import them into the upper part of your qml, cites the example of application a qml files in subfolders

See here:

https://github.com/BlackBerry/Cascades-samples/BLOB/master/quotes/assets/main.QML

EditScreen is imported in main.qml, and EditScreen is in assets/EditScreen/EditScreen.qml

I don't know if the name of the folder is the same as the qml file name is a convention, then I would try to mess around and see what works.

Adobe animate CC (2015) - how can incorporate you JS in the HTML file in the publication?

We need the ability to include all the inline Javascript in the HTML file using Adobe animate CC (2015).
Manually update the HTML code and referenced JS file after publishing a bandage isn't really an option as any Animate republish tasks will blow these manual changes.
Is there a way or an option to animate part of the edition to include all Javascript code in the HTML file published?
I searched on this here and the web and saw many others ask on the same topic, but have not seen any recent or formal Adobe responses.
Thanks in advance.

There is no built-in way to do currently. We seek to include this option for a future release.

I leave Apple Watch mangetic charger without turning on the card?

Can I leave the Apple Watch mangetic charger without turning on the charger?

When not to wear my watch, I put my Apple Watch on the stand of the watch...

Does magnetic can damage the battery if I let the watch for a long time?

Hello

Yes, you can leave your watch on the charger without the power connected. The magnet will not damage the battery.

If the power is rather left trendy, Apple Watch cannot be overloaded and again, the battery won't suffer wrong after normal use. Load stops automatically when it is fully charged (and restart as / when required due to the use of the current battery). Follow Apple's safety and handling instructions, and note also that:

-It is not possible to turn the watch off the coast while it is on the charger and connected to the power supply - what is normal.

-It is also normal to watch, adapter sector and charger become hot when it is connected to the power.

My Apple Watch will not charge on the charger. I cleaned the back of the watch and the charger. Any ideas?

My Apple Watch will not charge on the charger. I tried to clean the back of the watch and the charger more used several points of sale, but in vain. Any ideas?

Hello

When you reload your watch, check that:
- All the plastic film was removed from both ends and both sides of the cable support (consult closely on the head of the charger).
- On the back of your watch and the head of the charge cable are clean and dry (clean with an abrasive, lint cloth).
- The head of the load is properly aligned with the back of the watch, with the concave side / curve touch fully:
  - Some docks of watch, brackets, cases or protectors might hinder it.
- You use a real Apple magnetic Charging Cable or a certified Apple module magnetic charge.
- If you reload your watch by plugging into a power outlet:
  - Check that the magnetic charge cable Apple USB connector is fully engaged in the USB power adapter.
  - Try to use different maps of the following:
    - The real Apple USB Power Adapter that came with the watch, or;
    - A true 5W Apple (iPhone) or 12W (iPad) USB power adapter, or;
    - A third-party certified 5W (MFi) Apple USB power adapter.
  - Try to charge via a USB port (see following).
- If loading via a USB port on a computer, make sure that you use a USB 2.0 or 3.0 port, the computer remains turned on and awake, and the cable is plugged directly into the computer (not on, for example, an external keyboard).
- If your battery is very low, you may need to wait a few minutes for the green lightning appear (confirming that the charge has started).
Once the load has started, you can tap on the screen at any time to check the progress (leave a few minutes at the beginning, where the watch is in charge of a very low battery level). A green lightning bolt symbol indicates that your watch is being loaded. It is normal the screen back to sleep while continuous load.

iBook charged me twice for the same books

Hello

I bought books author michael Sinclair, but all of a sudden they disapeard in my library and when I tried to download iBook again charged me again for the same books?

How can I get my money back and my purchased books

Thank you

Ghalia

If you can redownload them depends on if the rights holder has removed their shop, or if you have moved since their purchase (and if you use the same account as you bought them with). You their redownloaded via the tab purchased in the iBooks on your iPad app (if they do not it check to see if you have hidden the cloud: mask and unmask purchases iTunes or iBooks on your Mac or PC - Apple support), or in the store (if they are the same version of the book they should have icons of cloud on them if it is not currently downloaded)?

If versions of the books that you have purchased have been removed and replaced by new books, they can be considered as new purchases (and would have a price on them button in the store), so you will be charged to buy these new versions.

If you wish to contact iTunes Support: http://reportaproblem.apple.com or https://www.apple.com/emea/support/itunes/contact.html

The charger is covered by the warranty?

My charger stopped working yesterday for no apparent reason. The charger is covered by the warranty? And how could I go to get a replacement charger?

Thanks for your help

Hello!

Normally the charger is covered by warranty when your laptop is guaranteed.

Contact an ASP (authorized service provider) to get a new one.
