                                           IResource[] resources)

      • ResourceListSelectionDialog

        public ResourceListSelectionDialog​(Shell parentShell,
                                           IContainer container,
                                           int typeMask)
        Creates a new instance of the class. When this constructor is used to create the dialog, resources will be gathered dynamically as the pattern string is specified. Only resources of the given types that match the pattern string will be listed. To further filter the matching resources,
        Parameters:
        parentShell - shell to parent the dialog on
        container - container to get resources from
        typeMask - mask containing IResource types to be considered

    • Method Detail

      • adjustPattern

        protected String adjustPattern()
        Adjust the pattern string for matching.
      • cancelPressed

        protected void cancelPressed()
        Description copied from class: Dialog
        Notifies that the cancel button of this dialog has been pressed.

        The Dialog implementation of this framework method sets this dialog's return code to Window.CANCEL and closes the dialog. Subclasses may override if desired.

        Overrides:
        cancelPressed in class Dialog
        See Also:
        Dialog.cancelPressed()
      • close

        public boolean close()
        Description copied from class: Window
        Closes this window, disposes its shell, and removes this window from its window manager (if it has one).

        This framework method may be extended (super.close must be called).

        Note that in order to prevent recursive calls to this method it does not call Shell#close(). As a result ShellListeners will not receive a shellClosed event.

        Overrides:
        close in class Dialog
        Returns:
        true if the window is (or was already) closed, and false if it is still open
        See Also:
        Window.close()
      • create

        public void create()
        Description copied from class: Window
        Creates this window's widgetry in a new top-level shell.

        The default implementation of this framework method creates this window's shell (by calling createShell), and its controls (by calling createContents), then initializes this window's shell bounds (by calling initializeBounds).

        Overrides:
        create in class Dialog
        See Also:
        Window.create()
      • createDialogArea

        protected Control createDialogArea​(Composite parent)
        Creates the contents of this dialog, initializes the listener and the update thread.
        Overrides:
        createDialogArea in class Dialog
        Parameters:
        parent - parent to create the dialog widgets in
        Returns:
        the dialog area control
      • getAllowUserToToggleDerived

        public boolean getAllowUserToToggleDerived()
        Returns whether to include a "Show derived resources" checkbox in the dialog. The default is false.
        Returns:
        true to include the checkbox, false to omit

      • setAllowUserToToggleDerived

        public void setAllowUserToToggleDerived​(boolean allow)
        Sets whether to include a "Show derived resources" checkbox in the dialog.
        Parameters:
        allow - true to include the checkbox, false to omit
        Since:
        3.1
      • getShowDerived

        protected boolean getShowDerived()
        Returns whether derived resources should be shown in the list. The default is false.
        Returns:
        true to show derived resources, false to hide them
        Since:
        3.1
      • setShowDerived

      • okPressed

        protected void okPressed()
        The user has selected a resource and the dialog is closing. Set the selected resource as the dialog result.
        Overrides:
        okPressed in class Dialog
      • select

        protected boolean select​(IResource resource)
        Use this method to further filter resources. As resources are gathered, if a resource matches the current pattern string, this method will be called. If this method answers false, the resource will not be included in the list of matches and the resource's children will NOT be considered for matching.
      • refresh

        protected void refresh​(boolean force)
        Refreshes the filtered list of resources. Called when the text in the pattern text entry has changed.
        Parameters:
        force - if true a refresh is forced, if false a refresh only occurs if the pattern has changed
        Since:
        3.1

        protected void updateOKState​(boolean state)
        Update the enabled state of the OK button. To be called when the resource list is updated.
