Java: Swing: Components: Actions: ActionEvent sources and ActionListeners
(no heavyweight AWT components)
Source | Action command |
|---|---|
Timer | null (undocumented) |
JTextField | set value (but no get, default is probably null), or text (iff value is null), |
AbstractButton | set/get to from model (implicitly done from action) - but taken from model's event, or text (iff value is null) |
ButtonModel | set/get: default unknown |
JFileChooser | APPROVE_SELECTION="ApproveSelection", CANCEL_SELECTION="CancelSelection" |
ComboBoxEditor | unspecified (probably unimportant, ChangeListener should have been used instead anyway) |
BasicComboBoxEditor | delegates to text field (that means it is the current text) |
JComboBox | set/get: default "comboBoxChanged" (documented?) 1.4: when event forwarded from editor: "comboBoxEdited" (what good is implementing such logic if it isn't documented?) |
Some places (BasicComboBoxUI, DefaultCellEditor for JComboBox, more?) also invoke JComboBox's actionPerformed by hand (they use "" as action command).
Class | Use | Classification |
|---|---|---|
BasicMenuItemUI | compares the menuItem's action command (not an event's) (with ==) to a fixed set of strings, if none of them, plays sound (in order not to play when the menu item is part of a internal frame "system menu".) | hack, will give false positives |
MotifInternalFrameTitlePane | uses the same ActionListener for multiple buttons/menu items | OK (internal) |
Class | Description |
|---|---|
Autoscroller | uses Timer |
AbstractButton | forwards ActionEvents from model |
JComboBox | forwards (with setSelectedItem logic) ActionEvents from editor |
JViewport | uses Timer for repainting later |
ToolTipManager | uses Timer for displaying/hiding etc. tooltip |
DefaultCellEditor | stop editing (text field, combo box, check box) |
DefaultTreeCellEditor | uses Timer for maybe starting editing later |
BasicComboBoxEditor | |
DefaultCaret | uses Timer for blinking |
html/FormView | submit data (or focus change, or reset) show file chooser (for file input fields) |
html/IsIndexView | follow URL |
JColorChooser DefaultHSBChooserPanel | ok, cancel, internal listeners |
java.awt.dnd.DropTarget | uses Timer for auto scrolling |
Class | Description |
|---|---|
BasicDropTargetListener | uses Timer for auto scrolling |
BasicComboBoxUI | hack to avoid swallowing enter (won't work if executed after combo box's, in fact break) (ActionListener on editor) |
BasicComboPopup | uses Timers for auto scrolling |
BasicProgressBarUI | uses Timer for animation (indeterminate) |
BasicScrollBarUI | uses Timer for auto scrolling |
BasicSliderUI | uses Timer for auto scrolling |
BasicSplitPaneDivider | one-touch-expandable button action listeners |
BasicSplitPaneUI | a lot of unused remains (now actions) |
BasicTreeUI | uses TImer/ComponentListener to possibly invalidate the tree |
MetalDesktopIconUI | on button (reshow frame) |
MotifDesktopIconUI | on button (show system menu) |
MotifInternalFrameTitlePane | on menu items, on button (show system menu) |
BasicOptionPaneUI | on text field -> transfer to input value on buttons -> transfer to value |
MetalFileChooserUI | on combo box (set as directory) on mode buttons on text field (editor???) |
WindowsFileChooserUI | like Metal; on shortcut panel buttons |
(i.e. given to a Timer or an addActionListener method)
Class | Description |
|---|---|
BasicMenuUI | for Timer (defer showing popup) |
BasicInternalFrameTitlePane | iconify, maximize, close buttons |
BasicSpinnerUI | action listeners on buttons, also used for Timer (auto-repeat) |
MetalFileChooserUI WindowsFileChooserUI | buttons: getGoHomeAction, getApproveSelectionAction, getCancelSelectionAction |
MotifFileChooserUI | buttons: getUpdateAction, getApproveSelectionAction, getCancelSelectionAction |
