Constructor Detail

ExpressionInformationControlCreator.ExpressionInformationControl

ExpressionInformationControlCreator.ExpressionInformationControl(Shell parentShell,
                                                                boolean resize)

Constructs a new control in the given shell.

Parameters:

parentShell - shell

resize - whether resize is supported

Method Detail

computeSizeHint

public Point computeSizeHint()

Description copied from interface: IInformationControl

Computes and returns a proposal for the size of this information control depending on the information to present. The method tries to honor known size constraints but might return a size that exceeds them.

Specified by:

computeSizeHint in interface IInformationControl

Overrides:

computeSizeHint in class AbstractInformationControl

Returns:

the computed size hint

dispose

public void dispose()

Description copied from interface: IInformationControl

Disposes this information control.

Specified by:

dispose in interface IInformationControl

Overrides:

dispose in class AbstractInformationControl

setVisible

public void setVisible(boolean visible)

Description copied from interface: IInformationControl

Controls the visibility of this information control.

Note: The information control must not grab focus when made visible.

Specified by:

setVisible in interface IInformationControl

Overrides:

setVisible in class AbstractInformationControl

Parameters:

visible - true if the control should be visible

createContent

protected void createContent(Composite parent)

Description copied from class: AbstractInformationControl

Creates the content of the popup window.

Implementors will usually take over Control.getBackground() and Control.getForeground() from parent.

Implementors are expected to consider AbstractInformationControl.isResizable(): If true, they should show scrollbars if their content may exceed the size of the information control. If false, they should never show scrollbars.

The given parent comes with a FillLayout. Subclasses may set a different layout.

Specified by:

createContent in class AbstractInformationControl

Parameters:

parent - the container of the content

initSashWeights

protected void initSashWeights()

Initializes the sash form weights from the preference store (using default values if no sash weights were stored previously).

setBackgroundColor

public void setBackgroundColor(Color background)

Description copied from interface: IInformationControl

Sets the background color of this information control.

Specified by:

setBackgroundColor in interface IInformationControl

Overrides:

setBackgroundColor in class AbstractInformationControl

Parameters:

background - the background color of this information control

setFocus

public void setFocus()

Description copied from class: AbstractInformationControl

This default implementation sets the focus on the popup shell. Subclasses can override or extend.

Specified by:

setFocus in interface IInformationControl

Overrides:

setFocus in class AbstractInformationControl

See Also:

IInformationControl.setFocus()

hasContents

public boolean hasContents()

Description copied from interface: IInformationControlExtension

Returns whether this information control has contents to be displayed.

Specified by:

hasContents in interface IInformationControlExtension

Returns:

true if there is contents to be displayed.

setInput

public void setInput(Object input)

Description copied from interface: IInformationControlExtension2

Sets the input to be presented in this information control. The concrete contract the input object is expected to adhere is defined by the implementer of this interface.

Specified by:

setInput in interface IInformationControlExtension2

Parameters:

input - the object to be used as input for this control

getInformationPresenterControlCreator

public IInformationControlCreator getInformationPresenterControlCreator()

Description copied from class: AbstractInformationControl

Returns the rich information control creator for this information control.

The returned information control creator is used to create an enriched version of this information control, e.g. when the mouse is moved into this control and it needs to be enriched or when it needs to be made sticky for other reasons.

The returned information control creator must create information controls that implement IInformationControlExtension3 and IInformationControlExtension2, and whose IInformationControlExtension2.setInput(Object) accepts all inputs that are also supported by this information control.

Note that automatic enriching of this information control works only if it also implements IInformationControlExtension3.

This method may be called frequently, so implementors should ensure it returns quickly, e.g. by caching the returned creator.

This default implementation returns null. Subclasses may override.

Specified by:

getInformationPresenterControlCreator in interface IInformationControlExtension5

Overrides:

getInformationPresenterControlCreator in class AbstractInformationControl

Returns:

the information presenter control creator or null to disable enriching
