GetClickedRow

In a mobile application, if the user clicks or double-clicks any area within a DataWindow, the GetClickedRow function returns the same value as in PowerBuilder. If the GetClickedRow is called in some control or window for a DataWindow, the return value is different on mobile than in PowerBuilder. For example, if the dw_1.GetClickedRow() function is called in the Clicked event of a CommandButton, it returns -1 in PowerBuilder and 0 on mobile.

ImportFile

ImportFile & ImportString

  1. The filename argument of ImportFile function must be a tab-separated file (TXT) or a comma-separated file (CSV).

  2. The importtype arguments (e.g. Text!, CSV! and XML!) of ImportString function are unsupported.

    The importtype arguments (e.g. Text!, CSV!, XML!, DBase2!, DBase3!) of ImportFile function are unsupported.

  3. When using these functions, you should ensure that the data type imported matches the data type that you specified in a DataWindow control, DataStore object or graph control. Otherwise the output on mobile may be different from that in PowerBuilder. For example, if the date type specified in a DataWindow is string, when you import a file with date number (e.g., 2006-08-01), on mobile the date data will be recognized as a string (2006), however in PowerBuilder, it will be recognized as a date data (2006-08-01).

Retrieve

Because Appeon cannot check whether the retrieve result set matches the DataWindow definition syntax, the DBError event will not be triggered.

Supported

RowCount

 

Supported

RowsCopy

 

Supported

RowsDiscard

For Composite, Group and Label DataWindows, if the current row is the start row, calling RowDiscard will not trigger RowFocusChanged on mobile. This is different from that in PowerBuilder.

Supported

RowsMove

Events cannot be triggered while the application moves data within the primary buffer of one DataWindow.

Supported

SaveAs

  1. The saveastype argument can be TEXT, HTMLTable, PDF, or EXCEL. For the EXCEL format, only up to 256 characters are supported and anything larger will be automatically truncated.

  2. The supported SaveAs syntax:

    ll_testvalue = dw_test.SaveAs(filename, saveastype, colheading, encoding)

    The unsupported SaveAs syntax:

    dw_test.SaveAs()
    dw_test.SaveAs([filename, ]graphcontrol[, saveastype, colheading])

    Note: For Appeon Mobile, when saveastype is PDF, the colheading and encoding arguments will be always executed as true and EncodingANSI!.

    For example, the following syntax:

    dw_1.SaveAs( filename, PDF!, false, EncodingUTF16BE! )

    will be executed as the following:

    dw_1.SaveAs( filename, PDF!, true, EncodingANSI! )

  3. If the DataWindow without any data is saved as an HTML file, the header will not be saved in Appeon Mobile, whereas it will be saved on PB.SetSort.

  4. When the file is generated via the SaveAs function on the mobile device, its file name is always in lower case, no matter which case you specify for the file name. This is as designed by Appeon Mobile. And since the mobile OS (such as iOS, Android) uses a case-sensitive file system, therefore, it is recommended you use lower case for the file name when developing an app for the mobile device.

  5. The generated file is automatically saved to the "plugin" folder under the current application directory. See "plugin" folder in Workarounds & APIs Guide for more.

Unsupported

SaveAsAscii

When executing the SaveAsAscii function in PowerBuilder, invisible controls which lay in rows will not be saved as empty rows or " " (quotation marks). However, these invisible controls will be ignored on mobile.

ShareData

ShareData and ShareDataOff

  1. Supported:

    CONNECT USING SQLCA;
dw_corp.SetTransObject(SQLCA)
dw_corp.Retrieve()
dw_corp.ShareData(dw_emp)
dw_corp.ShareData(dw_dept)
... // Some processing
dw_emp.ShareDataOff( )

  2. In mobile applications, if any data in two data-sharing Group DataWindows are changed, the primary Group DataWindow will be re-grouped and re-sorted automatically, while the secondary Group DataWindow will only be re-grouped.

  3. The row and column status is shared between the primary DataWindow and secondary DataWindow on mobile, although not shared in PowerBuilder.

Supported

ShareDataOff

Please see the notes for ShareData.

Supported

Supported

Sort

  1. Different from the Sort in PowerBuilder, the Sort function on mobile considers the "~" symbol to have precedence over characters. For this reason, the sort result may be a little different in mobile and PowerBuilder applications.

  2. In the mobile application, when the user sorts a DataWindow on a specified column, rows containing special characters (e.g. ".", "", "/") will be sorted in different order than in PowerBuilder.

Table 216. Properties

Property added by Appeon

Keyboardtype - Sets the type of the keyboard that displays when the DataWindow column gets focus: 0 - alphabetical keyboard, 1 - numerical keyboard, 2 - URL keyboard. 2 is unsupported on Android devices, thus 0 will be used instead.

You can manipulate this property though dot notation, Describe, or Modify , for example, dw_1.modify("#1.keyboardtype='2'").
