        Parameters:

      • getAutodisable

        @Nullable
default java.lang.String getAutodisable()
        Returns a list of component IDs that shall be disabled when the user clicks this button.

      • withAutodisable

        I withAutodisable​(@Nullable
                  java.lang.String autodisable)
        Returns a copy of this immutable component with the specified autodisable.

        Sets a list of component IDs that shall be disabled when the user clicks this button.

        To represent the button itself, the developer can specify self. For example, .withAutodisable("self,cancel"); is the same as IButton.ofId("ok").withAutodisable("ok,cancel"); that will disable both the ok and cancel buttons when a user clicks it.

        The button being disabled will be enabled automatically once the client receives a response from the server. In other words, the server doesn't notice if a button is disabled with this method.

        However, if you prefer to enable them later manually, you can prefix with '+'. For example, IButton.ofId("ok").withAutodisable("+self,+cancel");

        Then, you have to enable them manually such as 

        if (something_happened){
  uiAgent.smartUpdate(Locator.ofId("ok"), new IButton.Updater().disabled(false));
  uiAgent.smartUpdate(Locator.ofId("cancel"), new IButton.Updater().disabled(false));
        Parameters:
        autodisable - Whether it is auto-disable.

        Default: null.

        Returns:
        A modified copy of the this object

      • getTarget

        @Nullable
default java.lang.String getTarget()
        Returns the target frame or window.

        Note: it is useful only if href (withHref(java.lang.String)) is specified (i.e., use the onClick listener).

        Default: null.

      • withTarget

        I withTarget​(@Nullable
             java.lang.String target)
        Returns a copy of this immutable component with the specified target.

        Sets the target frame or window

        Parameters:
        target - The name of the frame or window to hyperlink.

        Default: null.

        Returns:
        A modified copy of the this object

      • getUpload

        @Nullable
default java.lang.String getUpload()
        Returns non-null if this component is used for file upload, or null otherwise. Refer to withUpload(java.lang.String) for more details.

        Default: null

      • withUpload

        I withUpload​(@Nullable
             java.lang.String upload)
        Returns a copy of this immutable component with the specified upload.

        Sets the JavaScript class at the client to handle the upload if this component is used for file upload.

        For example, the following example declares a button for file upload: 

        IButton.of("Upload").withUpload("true").withAction(onUpload(this::doHandle));

        As shown above, after the file is uploaded, an instance of FileData is sent this handler.

        If you want to customize the handling of the file upload at the client, you can specify a JavaScript class when calling this method: withUpload("foo.Upload");

        Another options for the upload can be specified as follows: 

        .withUpload("true,maxsize=-1,multiple=true,accept=audio/*|video/*|image/*,native");
        • maxsize: the maximal allowed upload size of the component, in kilobytes, or a negative value if no limit, if the maxsize is not specified, it will use Configuration.getMaxUploadSize()
        • native: treating the uploaded file(s) as binary, i.e., not to convert it to image, audio or text files.
        • multiple: treating the file chooser allows multiple files to upload, the setting only works with HTML5 supported browsers.
        • accept: specifies the types of files that the server accepts, the setting only works with HTML5 supported browsers.
        • suppressedErrors: specifies the suppressed uploading errors, separated by | (e.g. missing-required-component|illegal-upload) (since ZK 9.5.1).

        Note: if the options of the false or the customized handler (like foo.Upload) are not specified, the option of true is implicit by default.

        Parameters:
        upload - a JavaScript class to handle the file upload at the client, or "true" if the default class is used, or null or "false" to disable the file download (and then this button behaves like a normal button).

        Default: null.

        Returns:
        A modified copy of the this object

      • getHref

        @Nullable
default java.lang.String getHref()
        Returns the href that the browser shall jump to, if a user clicks this button.

        Default: null. If null, the button has no function unless you specify the onClick event listener.

        If it is not null, the onClick event won't be sent.

      • withHref

        I withHref​(@Nullable
           java.lang.String href)
        Returns a copy of this immutable component with the specified href.

        Sets he href that the browser shall jump to, if a user clicks this button.

        Parameters:
        href - The href that the browser shall jump to, if a user clicks this button.

        Default: null.

        Returns:
        A modified copy of the this object
