# Class ShareButton

java.lang.Object
com.codename1.ui.Component
com.codename1.ui.Label
com.codename1.ui.Button
com.codename1.components.ShareButton

All Implemented Interfaces:
  `Animation, Editable, ActionListener, ActionSource<ActionEvent>, StyleListener, IconHolder, ReleasableComponent, SelectableIconHolder, TextHolder`

public class ShareButton extends Button implements ActionListener

The share button allows sharing a String or an image either thru the defined sharing services or thru the native OS sharing support. On Android & iOS the native sharing API is invoked for this class.

The code below demonstrates image sharing, notice that an image must be stored using the `com.codename1.io.FileSystemStorage` API and shouldn't use a different API like `com.codename1.io.Storage`!

    Form hi = new Form("ShareButton");
    ShareButton sb = new ShareButton();
    sb.setText("Share Screenshot");
    hi.add(sb);

    Image screenshot = Image.createImage(hi.getWidth(), hi.getHeight());
    hi.revalidate();
    hi.setVisible(true);
    hi.paintComponent(screenshot.getGraphics(), true);

    String imageFile = FileSystemStorage.getInstance().getAppHomePath() + "screenshot.png";
    try(OutputStream os = FileSystemStorage.getInstance().openOutputStream(imageFile)) {
        ImageIO.getImageIO().save(screenshot, os, ImageIO.FORMAT_PNG, 1);
    } catch(IOException err) {
        Log.e(err);
    }
    sb.setImageToShare(imageFile, "image/png");

Notice that share looks different on a device

- ## Constructor Details

  - ### ShareButton

    public ShareButton()
    Default constructor

- ## Method Details

  - ### getTextToShare

    public String getTextToShare()
    Gets the text to share

  - ### setTextToShare

    public void setTextToShare(String textToShare)

    Sets the information to share

    ###### Parameters

    - `textToShare`

  - ### setImageToShare

    public void setImageToShare(String imagePath, String imageMimeType)

    Sets the image to share. Notice some sharing services cannot share image and a text, therefore if setTextToShare(...) is also used, the sharing service gives image sharing higher priority.

    ###### Parameters

    - `imagePath`: the full file path

    - `imageMimeType`: the image mime type e.g. image/png, image/jpeg

  - ### getImagePathToShare

    public String getImagePathToShare()
    Gets the image path to share

  - ### addShareService

    public void addShareService(ShareService share)

    Adds a sharing service.

    ###### Parameters

    - `share`: ShareService

  - ### setShareResultListener

    public void setShareResultListener(ShareResultListener listener)

    Listener invoked once when the underlying share sheet (native or fallback dialog) finishes. May be `null` to clear a prior listener.

    On platforms that cannot observe the chosen target the listener still fires with `ShareResult.sharedTo(String)` passing a `null` package name, so the app can resume its flow.

  - ### getShareResultListener

    public ShareResultListener getShareResultListener()
    Returns the listener registered via `setShareResultListener(ShareResultListener)` or null.

  - ### actionPerformed

    public void actionPerformed(ActionEvent evt)

    invoked when the button is pressed

    ###### Parameters

    - `evt`
    Specified by:
      `actionPerformed` in interface `ActionListener`

  - ### getPropertyNames

    public String[] getPropertyNames()

    A component may expose mutable property names for a UI designer to manipulate, this API is designed for usage internally by the GUI builder code

    ###### Returns

    the property names allowing mutation

    Overrides:
      `getPropertyNames` in class `Label`

  - ### getPropertyTypes

    public Class[] getPropertyTypes()

    Matches the property names method (see that method for further details).

    ###### Returns

    the types of the properties

    Overrides:
      `getPropertyTypes` in class `Label`

  - ### getPropertyValue

    public Object getPropertyValue(String name)

    Returns the current value of the property name, this method is used by the GUI builder

    ###### Parameters

    - `name`: the name of the property

    ###### Returns

    the value of said property

    Overrides:
      `getPropertyValue` in class `Label`

  - ### setPropertyValue

    public String setPropertyValue(String name, Object value)

    Sets a new value to the given property, returns an error message if failed and null if successful. Notice that some builtin properties such as "$designMode" might be sent to components to indicate application state.

    ###### Parameters

    - `name`: the name of the property

    - `value`: new value for the property

    ###### Returns

    error message or null

    Overrides:
      `setPropertyValue` in class `Label`
