3. 7.3 includes/display-layout.inc \panels_change_layout()

Form definition for the display layout converter.

This form is only triggered if the user attempts to change the layout for a display that has already had content assigned to it. It allows the user to select where the panes located in to-be-deleted panels should be relocated to.

Parameters

array $form: A structured FAPI $form array.

object $display instanceof panels_display \n: The panels_display object that was modified on the preceding display layout editing form.

string $new_layout_id: A string containing the name of the layout the display is to be converted to. These strings correspond exactly to the filenames of the *.inc files in panels/layouts. So, if the new layout that's been selected is the 'Two Column bricks' layout, then $new_layout_id will be 'twocol_bricks', corresponding to panels/layouts/twocol_bricks.inc.
