Create a new, empty color picker.
extends goog.ui.ComponentInstance Method Summary | |
addColors(?Array colors) Sets the array of colors to be displayed by the color picker. | |
canDecorate(?Element element) ⇒ boolean ColorPickers cannot be used to decorate pre-existing html, since the structure they build is fairly complicated. | |
createColorPalette_(?Array colors) Create a color palette for the color picker. | |
disposeInternal() Disposes of the component. Calls {@code exitDocument}, which is expected to remove event handlers and clean up the component. Propagates the call to the component's children, if any. Removes the component's DOM from the document unless it was decorated. | |
enterDocument() Renders the color picker inside the provided element. This will override the current content of the element. | |
focus() Sets the focus to the color picker's palette. | |
getColors() ⇒ ?Array Gets the array of colors displayed by the color picker. Modifying this array will lead to unexpected behavior. | |
getSelectedColor() ⇒ ?string Gets the color that is currently selected in this color picker. | |
getSelectedIndex() ⇒ number | |
getSize() ⇒ ?goog.math.Size Gets the number of columns displayed. | |
isFocusable() ⇒ boolean Returns true if the component is focusable, false otherwise. The default is true. Focusable components always have a tab index and allocate a key handler to handle keyboard events while focused. | |
onColorPaletteAction_(?goog.events.Event e) Handles actions from the color palette. | |
setColors(?Array colors) Sets the array of colors to be displayed by the color picker. | |
setColumnCount(number n) Sets the number of columns. Will throw an error after the picker has been rendered. | |
setFocusable(boolean focusable) Sets whether the component is focusable. The default is true. Focusable components always have a tab index and allocate a key handler to handle keyboard events while focused. | |
setSelectedColor(string color) Sets which color is selected. Noop if the color palette hasn't been created yet. | |
setSelectedIndex(number ind) Sets which color is selected. A value that is out-of-range means that no color is selected. | |
setSize((goog.math.Size|null|number) size) Sets the size of the palette. Will throw an error after the picker has been rendered. |
Static Method Summary | |
