Allow to manually set the gallery in FileTree

[qzminski]

It is not possible to manually set the gallery in FileTree in the custom modules. Again there is a limitation, now requiring a "type" field in the database. Can't we just have a new eval option?

This can be added in new 3.2 version without any core improvements.

We can use "isGallery"=>true or "isDownloads"=>true eval option for fileTree input.
And in FileTree widget instead of:

$this->blnIsGallery = (isset($GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['gallery_types']) && in_array($this->activeRecord->type, $GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['gallery_types']));
$this->blnIsDownloads = (isset($GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['downloads_types']) && in_array($this->activeRecord->type, $GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['downloads_types']));

use this:

$this->blnIsGallery = $this->isGallery || ((isset($GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['gallery_types']) && in_array($this->activeRecord->type, $GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['gallery_types'])));
$this->blnIsDownloads = $this->isDownloads || ((isset($GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['downloads_types']) && in_array($this->activeRecord->type, $GLOBALS['TL_DCA'][$this->strTable]['fields']['type']['eval']['downloads_types'])));

I agree with DyaGa.
