Direct Known Subclasses:

HTMLPane

public class HTMLFlow
extends Canvas
implements HasContentLoadedHandlers

Use the HTMLFlow component to display HTML content that should expand to its natural size without scrolling.

HTML content can be loaded and reloaded from a URL via the property contentsURL. This method of loading is for simple HTML content only; Smart GWT components should be loaded via the ViewLoader class.

NOTE: Since the size of an HTMLFlow component is determined by its HTML contents, this component will draw at varying sizes if given content of varying size. When using HTMLFlow components within a Layout, consider what will happen if the HTMLFlow renders at various sizes. An HTMLFlow which can expand should be placed in a container where other components can render smaller, where the container is allowed to scroll, or where there is padding to expand into.

HTMLFlow is a DataBoundComponent but only supports one method at this time, fetchRelatedData.

public HTMLFlow setContentsType(ContentsType contentsType)
                         throws java.lang.IllegalStateException

The default setting of null or 'fragment' indicates that HTML loaded from contentsURL is assumed to be an HTML fragment rather than a complete page. Set to "page" to load HTML as a standalone page, via an IFRAME.

contentsType:"page" should only be used for controlled HTML content, and only when such content cannot be delivered as an HTML fragment instead (the default). To dynamically load Smart GWT components, use ViewLoader, never this mechanism (click here for why).

Loading HTML content as a fragment is less resource intensive and avoids visual artifacts such as translucent media becoming opaque or disappearing when placed over an IFRAME.

Loading third-party, uncontrolled content could lead to the surrounding page disappearing if a user clicks on an HTML link with target=_top.

With contentsType:"page", loadingMessage is not supported, and only "GET" is supported for httpMethod.

Note that a native bug has been observed in Internet Explorer version 10 whereby if an HTMLFlow with contentsType set to "page" loads a page containing an HTML <frameset>, when the HTMLFlow is hidden, it can interfere with the rendering of other elements on the page. Setting Canvas.shrinkElementOnHide to true will work around this behavior.

Parameters:

contentsType - New contentsType value. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the component has been created

getContentsType

public ContentsType getContentsType()

Returns:

Current contentsType value. Default value is null

setContentsURL

public HTMLFlow setContentsURL(java.lang.String contentsURL)

URL to load content from.

If specified, this component will load HTML content from the specified URL when it is first drawn.

This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See PlatformDependencies for more information.

If this method is called after the component has been drawn/initialized: Change the URL this component loads content from. Triggers a fetch for content from the new URL.

Can also be called with no arguments to reload content from the existing contentsURL.

This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See PlatformDependencies for more information.

Parameters:

contentsURL - URL to retrieve contents from. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

See Also:

URL

getContentsURL

public java.lang.String getContentsURL()

URL to load content from.

If specified, this component will load HTML content from the specified URL when it is first drawn.

This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See PlatformDependencies for more information.

Returns:

Current contentsURL value. Default value is null

See Also:

URL

setContentsURLParams

public HTMLFlow setContentsURLParams(java.util.Map contentsURLParams)

Parameters to be sent to the contentsURL when fetching content.

Parameters:

contentsURLParams - New contentsURLParams value. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

setDynamicContents

public HTMLFlow setDynamicContents(java.lang.Boolean dynamicContents)

Dynamic contents allows the contents string to be treated as a simple but powerful template. When this attribute is set to true, JavaScript expressions may be embedded within the contents string, using the format: ${[JavaScript to evaluate]}.

For example, to include the current date in a templated message, canvas.contents could be set to:
"Today's date is <b>${new Date().toUSShortDate()}</b>"

Embedded expressions will be evaluated when the canvas is drawn or redrawn, and the result of the evaluated expression will be displayed to the user. If the expression does not evaluate to a String, the toString() representation of the returned object will be displayed automatically

Dynamic expressions are evaluated in the scope of the canvas displaying the content, so the this keyword may be used within your expression to refer to the canvas. Developers may also explicitly supply values for variables to be used within the evaluation via the Canvas.dynamicContentsVars property.

Notes:

• Calling markForRedraw() on the canvas will evaluate any embedded expressions.
• Multiple such expressions may be embedded within the contents string for a component.
• If an error occurs during evaluation, a warning is logged to the Developer Console and the error string will be embedded in place of the expected value in the Canvas.

Note : This is an advanced setting

Overrides:

setDynamicContents in class Canvas

Parameters:

dynamicContents - New dynamicContents value. Default value is false

Returns:

HTMLFlow instance, for chaining setter calls

setEvalScriptBlocks

public HTMLFlow setEvalScriptBlocks(java.lang.Boolean evalScriptBlocks)
                             throws java.lang.IllegalStateException

If evalScriptBlocks is true, HTMLFlow will pre-process the loaded HTML in order to mimic how the HTML would execute if it were loaded as an independent page or loaded via an IFRAME.

This feature is intended to assist with migrating existing applications to Smart GWT.

evalScriptBlocks is enabled by default when loading remote content (via contentsURL) and disabled by default for content supplied via setContents().

Note that, if evalScriptBlocks is false, <SCRIPT> blocks will still be detected and disabled to avoid the inconsistent results across different browsers.

Only applies when contentsType is not "page".

Parameters:

evalScriptBlocks - New evalScriptBlocks value. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the component has been created

setIframeSandbox

public HTMLFlow setIframeSandbox(java.lang.String iframeSandbox)
                          throws java.lang.IllegalStateException

When using contentsType ContentsType.PAGE, sets the <iframe> sandbox attribute to the provided value.

Use the value "*ALL*" to cause the "sandbox" attribute to be output with no value (which causes full sandboxing).

See any HTML reference for other legal values of the "sandbox" attribute, which allow you to remove individual restrictions on the loaded content.

Note that Smart GWT simply applies the provided value to the generated <iframe> element and cannot fix bugs or differences in sandbox behavior across different browsers.

Parameters:

iframeSandbox - New iframeSandbox value. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

Throws:

java.lang.IllegalStateException - this property cannot be changed after the component has been created

Returns:

Current iframeSandbox value. Default value is null

setLoadingMessage

public HTMLFlow setLoadingMessage(java.lang.String loadingMessage)

HTML to show while content is being fetched, active only if the contentsURL property has been set. Use "${loadingImage}" to include a loading image.

The loading message will show both during the initial load of content, and during reload if the contents are reloaded or the contentsURL changed. For a first-time only loading message, initialize the contents property instead.
Note: the loadingMessage is never displayed when loading complete web pages rather than HTML fragments (see contentsType).

Parameters:

setSelectContentOnSelectAll

public HTMLFlow setSelectContentOnSelectAll(java.lang.Boolean selectContentOnSelectAll)

When this HTMLFlow is focused, causes Ctrl-A / Command-A keypresses to select just the content, as opposed to all content on the screen becoming selected. This HTMLFlow must be focusable in order for this setting to have an effect.

Not valid with contentsType ContentsType.PAGE.

Parameters:

selectContentOnSelectAll - New selectContentOnSelectAll value. Default value is null

Returns:

HTMLFlow instance, for chaining setter calls

addContentLoadedHandler

public com.google.gwt.event.shared.HandlerRegistration addContentLoadedHandler(ContentLoadedHandler handler)

Add a contentLoaded handler.

StringMethod fired when content is completely loaded in this htmlFlow. Has no default implementation. Add a notification to fire custom logic when loading completes.

Notes:

• A call to this.setContents() will cause this notification to be fired when the contents have been set. If HTMLFlow.evalScriptBlocks is true, and the HTML passed into setContents() contains any <script src=... > tags, this callback will be fired asynchronously once the scripts have been loaded from the server and executed, as well as having the widget content updated
• When using HTMLFlow.contentsURL, this does not apply to htmlFlows with contentsType set to "page"

Specified by:

addContentLoadedHandler in interface HasContentLoadedHandlers

Parameters:

handler - the contentLoaded handler

Returns:

HandlerRegistration used to remove this handler

fetchRelatedData

public void fetchRelatedData(ListGridRecord record,
                             Canvas schema)

Based on the relationship between the DataSource this component is bound to and the DataSource specified as the "schema" argument, call fetchData() to retrieve records in this data set that are related to the passed-in record.

Relationships between DataSources are declared via DataSourceField.foreignKey.

For example, given two related DataSources "orders" and "orderItems", where we want to fetch the "orderItems" that belong to a given "order". "orderItems" should declare a field that is a foreignKey to the "orders" table (for example, it might be named "orderId" with foreignKey="orders.id"). Then, to load the records related to a given "order", call fetchRelatedData() on the component bound to "orderItems", pass the "orders" DataSource as the "schema" and pass a record from the "orders" DataSource as the "record" argument.

Note: When you expect a large number of records to be returned it is not recommended to display these in the DetailViewer as it doesn't have the same level of support for large datasets as the ListGrid.

Parameters:

record - DataSource record

schema - schema of the DataSource record, or DataBoundComponent already bound to that schema

HTMLString

setDefaultProperties

public static void setDefaultProperties(HTMLFlow hTMLFlowProperties)

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:

hTMLFlowProperties - properties that should be used as new defaults when instances of this class are created
