Method Detail

getEditingType

int getEditingType()

Framework calls this method to decide which UI to show up.

Returns:

the editing type

canDirectEdit

boolean canDirectEdit(IDirectEditingContext context)

Checks if the feature can perform direct editing on the context handed over.

Parameters:

context - the context

Returns:

This method is equivalent to

IDirecEditingFeature.canExecute()

getInitialValue

java.lang.String getInitialValue(IDirectEditingContext context)

Provides the initial value for the opened text editing UI component.

Parameters:

context - the context

Returns:

the initial value

getPossibleValues

java.lang.String[] getPossibleValues(IDirectEditingContext context)

This value will be used if the cell editor is a combo box. This functionality only applies to TYPE_DROPDOWN.

Parameters:

context - the context

Returns:

the possible values for the combo box.

getValueProposals

java.lang.String[] getValueProposals(java.lang.String value,
                                     int caretPosition,
                                     IDirectEditingContext context)

This proposals will be used for the completion list of a simple text cell editor. This functionality only applies to TYPE_TEXT.

Parameters:

value - current value

caretPosition - current cursor position

context - the context

Returns:

the proposed values

completeValue

java.lang.String completeValue(java.lang.String value,
                               int caretPosition,
                               java.lang.String choosenValue,
                               IDirectEditingContext context)

Framework calls this method to let the feature calculate the new value.

Parameters:

value - current value

caretPosition - current cursor position

choosenValue - value choosen by user

context - the context

Returns:

the new value

isCompletionAvailable

boolean isCompletionAvailable()

Checks if completion is available. This functionality only applies to TYPE_TEXT.

Returns:

true if completion is / proposals are available at all

isAutoCompletionEnabled

boolean isAutoCompletionEnabled()

Checks if auto completion is enabled. This functionality only applies to TYPE_TEXT.

Returns:

true, if proposals should appear automatically

stretchFieldToFitText

boolean stretchFieldToFitText()

Stretch input field to fit its contents. This functionality applies to TYPE_TEXT, TYPE_DROPDOWN and TYPE_DROPDOWN_READ_ONLY.

Returns:

true if the field should exactly fit the contents

checkValueValid

java.lang.String checkValueValid(java.lang.String value,
                                 IDirectEditingContext context)

This method will be called by clients many times to see if current value is valid and could be set.

Parameters:

value - the value

context - the context

Returns:

null if value is okay and could be set; any text means value is not valid; text is reason for invalidality

setValue

void setValue(java.lang.String value,
              IDirectEditingContext context)

Set the new value. The value comes from the text editing UI component.

Parameters:

value - the value

context - the context

getProposalSupport

IProposalSupport getProposalSupport()

The direct editing mode contains controls for code completion and the selection from a combo box. In both cases the standard implementation supports only strings.

If the customer wants to work with Objects he must provide an implementation of IProposalSupport. In this case the following methods of IDirectEditing are ignored:


* String checkValueValid(String value, IDirectEditingContext context);
* String completeValue(String value, int caretPosition, String choosenValue, IDirectEditingContext context);
* String[] getPossibleValues(IDirectEditingContext context);
* String[] getValueProposals(String value, int caretPosition, IDirectEditingContext context);
* void setValue(String value, IDirectEditingContext context);

Returns:

the special implementation to support Objects in code completion and combo box
