to change the Iframe size, the only parameter you can make edit is this:
rel="facebox" rev="iframe|630|900"
The iframe HTML tag is not hard coding. it is generated by facebox plugin dynamically. It will be resized by firebug because firebug sees the already generated HTML tags, but in the background, there is no iframe tag to modify. It is generated dynamically by FACEBOX plugin. Facebox is a 3rd party plugin to create iframe based modal popups. You can find more info in the official page:
defunkt.io/facebox/
Please follow my steps:
/templates/flexible_darkmart/html/com_virtuemart/category/default.php
1- To change the quicklook sizing for "ListView"
Look at the 231st line:
<?php if ($params->get('category_list_quicklook',1)) { ?>
<div class="FlexibleProductHoverShadowButtons"> <a class="FlexibleProductHoverShadowQUICK" title="<?php echo $product->product_name; ?>" rel="facebox" rev="iframe|550|900"...........
change the rev="iframe|550|900" to rev="iframe|630|900"
2- To change the quicklook sizing for "GridView"
Look at the 629th line:
<?php if ($params->get('category_grid_quicklook',1)) { ?>
<a class="FlexibleProductHoverShadowQUICK" title="<?php echo $product->product_name; ?>" rel="facebox" rev="iframe|550|900".....
change the rev="iframe|550|900" to rev="iframe|630|900"
3- To change the quicklook sizing for "MultiGridView"
Look at the 980th line:
<?php if ($params->get('category_multi_quicklook',1)) { ?>
<a class="FlexibleProductHoverShadowQUICK" title="<?php echo $product->product_name; ?>" rel="facebox" rev="iframe|550|900"......
change the rev="iframe|550|900" to rev="iframe|630|900"
Now which ever View you are looking at (ListView, GridView or MultiGridView) if you click the "QuickLook" button, the iframe and the modal popup will be width:900, height:630
