    • setActionType

      public StretchImgButton setActionType(SelectionType actionType)
      Behavior on state changes -- BUTTON, RADIO or CHECKBOX

      If this method is called after the component has been drawn/initialized: Update the 'actionType' for this canvas (radio / checkbox / button) If the canvas is currently selected, and the passed in actionType is 'button' this method will deselect the canvas.
      Overrides:
      setActionType in class StatefulCanvas
      Parameters:
      actionType - new action type. Default value is "button"
      Returns:
      StretchImgButton instance, for chaining setter calls
      See Also:

    • getActionType

      public SelectionType getActionType()
      Behavior on state changes -- BUTTON, RADIO or CHECKBOX
      Overrides:

    • setAlign

      public StretchImgButton setAlign(Alignment align)
      Horizontal alignment of this component's title.
      Overrides:
      setAlign in class StatefulCanvas
      Parameters:
      align - New align value. Default value is Canvas.CENTER
      Returns:

      See Also:

    • getAlign

      public Alignment getAlign()
      Horizontal alignment of this component's title.
      Overrides:
      getAlign in class StatefulCanvas
      Returns:
      Current align value. Default value is Canvas.CENTER
      See Also:

    • setAutoFit

      public StretchImgButton setAutoFit(Boolean autoFit)
      If true, ignore the specified size of this widget and always size just large enough to accommodate the title. If setWidth() is explicitly called on an autoFit:true button, autoFit will be reset to false.

      Note that for StretchImgButton instances, autoFit will occur horizontally only, as unpredictable vertical sizing is likely to distort the media. If you do want vertical auto-fit, this can be achieved by simply setting a small height, and having overflow:"visible"

      If this method is called after the component has been drawn/initialized: Setter method for the StatefulCanvas.autoFit property. Pass in true or false to turn autoFit on or off. When autoFit is set to false, canvas will be resized to it's previously specified size.

      Overrides:
      setAutoFit in class StatefulCanvas
      Parameters:
      autoFit - New autoFit setting. Default value is null
      Returns:
      StretchImgButton instance, for chaining setter calls
      See Also:

    • getAutoFit

      public Boolean getAutoFit()
      If true, ignore the specified size of this widget and always size just large enough to accommodate the title. If setWidth() is explicitly called on an autoFit:true button, autoFit will be reset to false.

      Note that for StretchImgButton instances, autoFit will occur horizontally only, as unpredictable vertical sizing is likely to distort the media. If you do want vertical auto-fit, this can be achieved by simply setting a small height, and having overflow:"visible"

      Overrides:
      getAutoFit in class StatefulCanvas
      Returns:
      Current autoFit value. Default value is null
      See Also:

    • setBaseStyle

      public StretchImgButton setBaseStyle(String baseStyle)
      Base CSS style className applied to the component.

      Note that if specified, this property takes precedence over any specified StatefulCanvas.styleName. If unset, the styleName will be used as a default baseStyle value.

      As the component changes StatefulCanvas.state and/or is selected, suffixes will be added to the base style. In some cases more than one suffix will be appended to reflect a combined state ("Selected" + "Disabled", for example).

      See StatefulCanvas.getStateSuffix() for a description of the default set of suffixes which may be applied to the baseStyle

      Rotated Titles

      The Framework doesn't have built-in support for rotating button titles in a fashion similar to FacetChart.rotateLabels. However, you can manually configure a button to render with a rotated title by applying custom CSS via this property.

      For example, given a button with a height of 120 and a width of 48, if you copied the existing buttonXXX style declarations from skin_styles.css as new, rotatedTitleButtonXXX declarations, and then added the lines: 

            -ms-transform:     translate(-38px,0px) rotate(270deg);
      -webkit-transform: translate(-38px,0px) rotate(270deg);
      transform:         translate(-38px,0px) rotate(270deg);
      overflow: hidden;
      text-overflow: ellipsis;
      width:116px;
      in the declaration section beginning: 
        .rotatedTitleButton,
  .rotatedTitleButtonSelected,
  .rotatedTitleButtonSelectedOver,
  .rotatedTitleButtonSelectedDown,
  .rotatedTitleButtonSelectedDisabled,
  .rotatedTitleButtonOver,
  .rotatedTitleButtonDown,
  .rotatedTitleButtonDisabled {
      then applying that style to the button with overflow: "clip_h" would yield a vertically-rendered title with overflow via ellipsis as expected, and also wrap with Button.wrap. Note that:
      • The explicit width applied via CSS is needed because rotated elements don't inherit dimensions in their new orientation from the DOM - the transform/rotation occurs independently of layout.
      • The translation transform required along the x-axis is roughly (width - height) / 2, but may need slight offsetting for optimal centering.
      • We've explicitly avoided describing an approach based on CSS "writing-mode", since support is incomplete and bugs are present in popular browsers such as Firefox and Safari that would prevent it from being used without Framework assistance.

      Note on css-margins: Developers should be aware that the css "margin" property is unreliable for certain subclasses of StatefulCanvas, including buttons. Developers may use the explicit Canvas.margin property to specify button margins, or for a button within a layout, consider the layout properties Layout.layoutMargin, Layout.membersMargin

      If this method is called after the component has been drawn/initialized: Sets the base CSS style. As the component changes state and/or is selected, suffixes will be added to the base style.

      Overrides:
      setBaseStyle in class StatefulCanvas
      Parameters:
      baseStyle - new base style. Default value is "stretchImgButton"
      Returns:
      StretchImgButton instance, for chaining setter calls
      See Also:

    • getBaseStyle

      public String getBaseStyle()
      Base CSS style className applied to the component.

      overflow: hidden;
      text-overflow: ellipsis;

      setIconSize in class StatefulCanvas
      Parameters:
      iconSize - New iconSize value. Default value is 16
      Returns:

    • setLabelBreadthPad

      public StretchImgButton setLabelBreadthPad(Integer labelBreadthPad)
      The padding for a StretchImgButton's label is determined as follows.

      If labelHPad is set it will specify the horizontal padding applied to the label. Similarly if labelVPad is set it will specify the vertical padding for the label, regardless of the button's vertical setting.

      Otherwise labelLengthPad can be set to specify the label padding along the length axis (ie: horizontal padding if vertical is false, otherwise vertical padding), and labelBreadthPad can be set to specify the label padding along the other axis.

      Otherwise the padding on the length axis will match the capSize and will be set to zero on the breadth axis.

      So by default the label will be sized to match the center image of the StretchImgButton, but these settings allow the label to partially or wholly overlap the caps.

      Parameters:
      labelBreadthPad - New labelBreadthPad value. Default value is null
      Returns:
      StretchImgButton instance, for chaining setter calls

    • setSrc

      public StretchImgButton setSrc(String src)
      Base URL for the image. By default, StretchImgButtons consist of three image parts: A start image (displayed at the top or left), a scalable central image and an end image displayed at the bottom or right.

      The images displayed in the stretchImgButton are derived from this property in the following way:

      • When the button is in its standard state the suffixes "_start", "_end" and "_stretch" are applied to the src (before the file extension), so by default the images displayed will be "button_start.gif" (sized to be this.capSize by the specified width of the stretchImgButton), "button_stretch.gif" (stretched to the necessary width) and "button_end.gif" (sized the same as the start image).
      • As the button's state changes, the images will have suffixes appended before the "_start" / "_end" / "_stretch" to represent the button state. See Img.src for an overview of how states are combined into a compound URL.
      For example the center piece of a selected stretchImgButton with the mouse hovering over it might have the URL: "button_Selected_Down_stretch.gif".

      Media should be present for each possible state of the _start, _end and _stretch images.

      Overrides:
      setSrc in class StretchImg
      Parameters:
      src - New src value. Default value is "button.gif"

    • setState

      public StretchImgButton setState(State state)
      Current "state" of this widget. The state setting is automatically updated as the user interacts with the component (see StatefulCanvas.showRollOver, StatefulCanvas.showDown, StatefulCanvas.showDisabled).

      StatefulCanvases will have a different appearance based on their current state. By default this is handled by changing the css className applied to the StatefulCanvas - see StatefulCanvas.baseStyle and StatefulCanvas.getStateSuffix() for a description of how this is done.

      For Img or StretchImg based subclasses of StatefulCanvas, the appearance may also be updated by changing the src of the rendered image. See Img.src and src for a description of how the URL is modified to reflect the state of the widget in this case.

      If this method is called after the component has been drawn/initialized: Sets the state of this object, changing its appearance. Note: newState cannot be State.STATE_DISABLED if this.showDisabled is false.

      Note : This is an advanced setting

    • setTitleStyle

      public StretchImgButton setTitleStyle(String titleStyle)
      CSS style applied to the title text only. Defaults to baseStyle when unset.

      With a separate titleStyle and baseStyle set, you can provide a backgroundColor via baseStyle that will allow translucent .png media to be "tinted" by the underlying background color, so that a single set of media can provide range of color options. In this usage, the titleStyle should generally not specify a background color as this would block out the media that appears behind the title.

      If this method is called after the component has been drawn/initialized: Sets the titleStyle, which is applied to the title text.

      Overrides:
      setTitleStyle in class StatefulCanvas

    • setDefaultProperties

      public static void setDefaultProperties(StretchImgButton stretchImgButtonProperties)
      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:
      stretchImgButtonProperties - properties that should be used as new defaults when instances of this class are created

    • setTitleHoverFormatter

      public void setTitleHoverFormatter(TitleHoverFormatter formatter)
