Survey 123 template in App Studio - load multiple predetermined surveys
Accepted Solutions
Hi Yulia,
I think that the downloading sequence is happening too fast - the second download is attempting to start before the downloaded() signal for the first form has been fired. To accommodate this, I restructured the loop to be incremented by the onDownloaded function in the OpenParametersPanel. The specifics are (All on SurveysGalleryPage.qml😞
1. Create properties for SurveysGalleryPage that are the list of forms and the current position in the index:
2. Begin the download of the first item in Component.onCompleted and have a handler for dl_num to download the next survey when that variable is incremented (I placed this immediately below the property statements:
3. In the OpenParametersPanel, add the loop logic and incrementation to increase dl_num after a download has succeeded:
4. (Optional). The OpenParameters were designed with the expectation that only 1 survey would be requested when the app is opened; part of the workflow of using OpenParameters is to open the form after download. This is done through the selected() function in checkOpenParameters(). Since you are downloading multiple forms, it's not known which form should be immediately open after download; to prevent both forms from opening on the stack, I disabled the selected() function:
If you know which should be opened, you could instead check for it based on itemID. The other forms would continue to download.
Hi James,
I tried for loop to iterate through an array with item ids that I want to download, but it still only downloads the first one when I run. Please look at my code:
I run it in QT Creator, and this is what I see:
It checks the second form too, but it's not downloading it. Please suggest!
Thank you,
Yulia
