Widget XML tag
GnEmail provides support to enter email data into email datatype. It is used to store and retrieve data from the database. Once data is in the widget it’s possible to edit the data by clicking edit button.
On click, a new dialog window will open which has add, edit, remove and close buttons which can be used to manipulate emails.
The dialog has a built in validate screen action when add or edit is executed.
By default, widget definition can be found in $defaultApp/control/widget_en_email.xml. This layout describes how the widget will look on screen.
The dialog screen that loads on clicking edit can be found at $defaultApp/control/dialog_en_email.xml
Dialog screen listview row definition can be found at $defaultApp/control/dialog_en_email_row.xml
All of the aforementioned layouts can be used to modify the look and feel of the widget.

XML Attributes Description



  android:layout_height="wrap_content" />

Alternative layout

If the default look and feel needs to be changed, create or copy identical files from $defaultApp to current app "control" folder.

To provide alternative layout, the files mentioned above can be set into control folder of the current application. Files must be named as shown above and widgets with Id’s have to stay of same type and keep same id.


TextView @+id/etEmail
this text field represents emails stored in the widget
this button opens dialog screen to manage email entries


GnEditText @+id/etEmailDialogName
this input field is used to define email entry name attribute
GnEditText @+id/etEmailDialogAddress
this input field is used to define email entry email attribute
ListView @+id/lstEmailDialogAddresses
displays currently stored email entries in widget
this button adds data that is set into GnEditTexts into widget and refreshes the listview
this button, after clicking on list item and modifying entry data, will replace stored entry data with newly entered data
after clicking on list item, clicking this button will remove the entry from the list
this button closes dialog and refreshes widget on screen with data


LinearLayout @+id/etEmailRow
this container represents a single list row
TextView @+id/etEmailName
this text widget will display email entry name attribute
TextView @+id/etEmailRowAddress
this text widget will display email entry email attribute

The aforementioned widgets must keep their type and id but the rest of the attributes and customisations can be done as required. Remaining widgets not mentioned in this xml files structure can be added/modified as required, there are no constraints.
