changeAutoChildDefaults
Changes the defaults for Canvas AutoChildren namedautoChildName.- Parameters:
autoChildName- name of an AutoChild to customize the defaults for.defaults- Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, seeSGWTProperties.- See Also:
-
changeAutoChildDefaults
Changes the defaults for FormItem AutoChildren namedautoChildName.- Parameters:
autoChildName- name of an AutoChild to customize the defaults for.defaults- FormItem defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, seeSGWTProperties.- See Also:
-
create
- Overrides:
createin classStatefulCanvas
-
setAltText
If specified this property will be included as thealttext for the image HMTL element. This is useful for improving application accessibility.altTextand hover prompt / tooltip behavior: Note that some browsers, including Internet Explorer 9, show a native hover tooltip containing the img tag'saltattribute. Developers should not rely on this behavior to show the user a hover prompt - instead thepromptattribute should be used.
To set alt text and ensure a hover prompt shows up in all browsers, developers may setpromptandaltTextto the same value. If both these attributes are set, the standard Smart GWT prompt behavior will show a hover prompt in most browsers, but will be suppressed for browsers where a native tooltip is shown for altText. Note that settingaltTextandpromptto different values is not recommended - the prompt value will be ignored in favor of the altText in this case.- Parameters:
altText- New altText value. Default value is null- Returns:
Imginstance, for chaining setter calls- See Also:

- Current altText value. Default value is null
- See Also:
-
setEditProxyConstructor

- Current imageHeight value. Default value is null
- See Also:
-
setImageSize
Convenience for setting the ${isc.DocUtils.linkForRef('attr:Img.imageWidth','imageWidth) and \nimageHeight')attributes to the same value, for cases whereimageTypesettings would normally use the image's natural size (applies toimageType"center" and "normal" only).- Parameters:

- Current imageSize value. Default value is null
- See Also:
-
setImageType
Indicates whether the image should be tiled/cropped, stretched, or centered when the size of this widget does not match the size of the image. CENTER shows the image in it's natural size, but can't do so while the transparency fix is active for IE. The transparency fix can be manually disabled by settingusePNGFixto false.

srchas not changed but other state has changed such that the image needs updating, callresetSrc()instead.- Parameters:
src- new URL for the image. Default value is "[SKINIMG]blank.gif"- Returns:
Imginstance, for chaining setter calls- See Also:
-

-

If this method is called after the component has been drawn/initialized: Changes the URL of this image and redraws it.Does nothing if the src has not changed - if
srchas not changed but other state has changed such that the image needs updating, callresetSrc()instead.- Parameters:
src- new URL for the image. Default value is "[SKINIMG]blank.gif"- Returns:

resetSrc
public void resetSrc()Refresh the image being shown. Call this when thesrcattribute has not changed, but other state that affects the image URL (such as being selected) has changed.- See Also:
-
setDefaultProperties
Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.
- Parameters:
imgProperties- properties that should be used as new defaults when instances of this class are created- See Also:
-
setHoverHTMLCustomizer
Ifthis.showHoveris true, when the user holds the mouse over this Canvas for long enough to trigger a hover event, a hover canvas is shown by default. This method returns the contents of that hover canvas.Overridden from Canvas:
Ifpromptis specified, andaltTextis unset, default implementation is unchanged - the prompt text will be displayed in the hover.
IfaltTextandpromptare set this method will return null to suppress the standard hover behavior in browsers where the alt attribute on an img tag causes a native tooltip to appear, such as Internet Explorer. On other browsers the altText value will be returned.- Parameters:
hoverHTMLCustomizer- the customizer to execute.
