|
|
MediaManagerItem is a helper widget for plugins.
|
|
|
|
None of the following *need* to be used, feel free to override them completely in your plugin's implementation.
|
|
Alternatively, call them from your plugin before or after you've done extra things that you need to.
|
|
|
|
**Constructor Parameters**
|
|
|
|
``parent``
|
|
The parent widget. Usually this will be the *Media Manager* itself. This needs to be a class descended from
|
|
``QWidget``.
|
|
|
|
``plugin``
|
|
The plugin widget. Usually this will be the *Plugin* itself. This needs to be a class descended from ``Plugin``.
|
|
|
|
**Member Variables**
|
|
|
|
When creating a descendant class from this class for your plugin, the following member variables should be set.
|
|
|
|
``self.on_new_prompt``
|
|
|
|
Defaults to *'Select Image(s)'*.
|
|
|
|
``self.on_new_file_masks``
|
|
Defaults to *'Images (*.jpg *jpeg *.gif *.png *.bmp)'*. This assumes that the new action is to load a file. If
|
|
not, you need to override the ``OnNew`` method.
|
|
|
|
``self.PreviewFunction``
|
|
This must be a method which returns a QImage to represent the item (usually a preview). No scaling is required,
|
|
that is performed automatically by OpenLP when necessary. If this method is not defined, a default will be used
|
|
(treat the filename as an image).
