Class HiddenItem
- All Implemented Interfaces:
HasHandlers,HasBlurHandlers,HasChangedHandlers,HasChangeHandlers,HasClickHandlers,HasDoubleClickHandlers,HasEditorEnterHandlers,HasEditorExitHandlers,HasFocusHandlers,HasIconClickHandlers,HasIconKeyPressHandlers,HasItemHoverHandlers,HasKeyDownHandlers,HasKeyPressHandlers,HasKeyUpHandlers,HasPendingStatusChangedHandlers,HasPickerIconClickHandlers,HasShowContextMenuHandlers,HasTitleClickHandlers,HasTitleDoubleClickHandlers,HasTitleHoverHandlers,HasValueHoverHandlers,HasValueIconClickHandlers
When using
Smart GWT databinding it is usually not necessary to use a HiddenItem, since the DynamicForm will track values for which
no actual form control exists, and will submit these 'extra' values when DynamicForm.saveData() is called. HiddenItems only apply to
forms that are submitted like ordinary HTML forms, via the DynamicForm.submitForm() method.

changeAutoChildDefaults
Changes the defaults for Canvas AutoChildren namedautoChildName.- Parameters:
autoChildName- name of an AutoChild to customize the defaults for.defaults- Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, seeSGWTProperties.- See Also:
-
changeAutoChildDefaults
Changes the defaults for FormItem AutoChildren namedautoChildName.- Parameters:
autoChildName- name of an AutoChild to customize the defaults for.defaults- FormItem defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, seeSGWTProperties.- See Also:
-
changePickerIconDefaults

setAlwaysFetchMissingValues
If this form item has a specifiedFormItem.optionDataSourceandFormItem.fetchMissingValuesis true, when the item value changes, a fetch will be performed against the optionDataSource to retrieve the related record ifFormItem.displayFieldis specified and the new item value is not present in any valueMap explicitly specified on the item.Setting this property to true means that a fetch will occur against the optionDataSource to retrieve the related record even if
FormItem.displayFieldis unset, or the item has a valueMap which explicitly contains this field's value.An example of a use case where this might be set would be if
FormItem.formatValue()orFormItem.formatEditorValue()were written to display properties from theselected record.Note - for efficiency we cache the associated record once a fetch has been performed, meaning if the value changes, then reverts to a previously seen value, we do not kick off an additional fetch even if this property is true. If necessary this cache may be explicitly invalidated via a call to
FormItem.invalidateDisplayValueCache()Note: For hiddenItem
fetchMissingValuesis defaulted tofalseso developers wishing to get access to the record related to the current hiddenItem value would need to explicitly set both that property, and this one to true.Note : This is an advanced setting
- Overrides:
setAlwaysFetchMissingValuesin classFormItem- Parameters:
alwaysFetchMissingValues- New alwaysFetchMissingValues value. Default value is false- Returns:
HiddenIteminstance, for chaining setter calls
-
getAlwaysFetchMissingValues
If this form item has a specifiedFormItem.optionDataSourceandFormItem.fetchMissingValuesis true, when the item value changes, a fetch will be performed against the optionDataSource to retrieve the related record ifFormItem.displayFieldis specified and the new item value is not present in any valueMap explicitly specified on the item.Setting this property to true means that a fetch will occur against the optionDataSource to retrieve the related record even if
FormItem.displayFieldis unset, or the item has a valueMap which explicitly contains this field's value.An example of a use case where this might be set would be if

fetchMissingValuesis defaulted tofalseso developers wishing to get access to the record related to the current hiddenItem value would need to explicitly set both that property, and this one to true.- Overrides:
getAlwaysFetchMissingValuesin classFormItem- Returns:
- Current alwaysFetchMissingValues value. Default value is false
-
setColSpan
hidden fields don't take up any columns- Overrides:
setColSpanin classFormItem- Parameters:
colSpan- New colSpan value. Default value is 0- Returns:
HiddenIteminstance, for chaining setter calls- See Also:
-
getColSpan
public int getColSpan()hidden fields don't take up any columnsNote : This method will return -1 if the underlying SmartClient JavaScript attribute value cannot be expressed as a(n) int. In that case, other getters, similarly-named but ending in
AsString,AsCanvas, etc., may be provided.- Returns:
- Current colSpan value. Default value is 0
- See Also:
-
setColSpan
hidden fields don't take up any columns- Overrides:
setColSpanin classFormItem- Parameters:
colSpan- New colSpan value. Default value is 0- Returns:
HiddenIteminstance, for chaining setter calls- See Also:
-
getColSpanAsString
hidden fields don't take up any columns- Returns:
- Current colSpan value. Default value is 0
- See Also:
-
setFetchMissingValues
If this form item has a specifiedFormItem.optionDataSource, should the item ever perform a fetch against this dataSource to retrieve the related record.This is disabled by default for hiddenItems as there is typically no need to perform a fetch and retrieve a display-field value to show the user for a hidden item. This does mean that if a developer needs access to the related record for a hidden-item's value, they will need to enable both this setting and
FormItem.alwaysFetchMissingValues.Note : This is an advanced setting
- Overrides:
setFetchMissingValuesin classFormItem- Parameters:
fetchMissingValues- New fetchMissingValues value. Default value is true- Returns:
HiddenIteminstance, for chaining setter calls- See Also:
-
getFetchMissingValues
If this form item has a specifiedFormItem.optionDataSource, should the item ever perform a fetch against this dataSource to retrieve the related record.This is disabled by default for hiddenItems as there is typically no need to perform a fetch and retrieve a display-field value to show the user for a hidden item. This does mean that if a developer needs access to the related record for a hidden-item's value, they will need to enable both this setting and
FormItem.alwaysFetchMissingValues.- Overrides:
getFetchMissingValuesin classFormItem- Returns:
- Current fetchMissingValues value. Default value is true
- See Also:
-
setRowSpan
hidden fields don't take up any rows- Overrides:
setRowSpanin classFormItem- Parameters:
rowSpan- New rowSpan value. Default value is 0- Returns:
HiddenIteminstance, for chaining setter calls- See Also:
-
getRowSpan
public int getRowSpan()hidden fields don't take up any rows- Overrides:
getRowSpanin classFormItem- Returns:
- Current rowSpan value. Default value is 0
- See Also:
-
setShowTitle
we never show a separate title cell for hidden fields- Overrides:
setShowTitlein classFormItem- Parameters:
showTitle- New showTitle value. Default value is false- Returns:
HiddenIteminstance, for chaining setter calls- See Also:
-
getShowTitle
we never show a separate title cell for hidden fields- Overrides:
getShowTitlein classFormItem- Returns:
- Current showTitle value. Default value is false
- See Also:
-
setDefaultProperties
Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
- Parameters:
hiddenItemProperties- properties that should be used as new defaults when instances of this class are created- See Also:
-
