I have a clutter texture as my background . I need to put some clutter actors over it. is it possible to do it . Since i get the following error:
"invalid cast from `ClutterTexture' to `ClutterContainer' "
Can any one help me ?
ClutterTexture is not a container, i.e. it cannot contain other actors.
ClutterBox and ClutterGroup are containers available in Clutter; ClutterBox allows using different layout managers - like ClutterBinLayout:
http://developer.gnome.org/clutter/stable/ClutterBinLayout.html
or ClutterFixedLayout:
http://developer.gnome.org/clutter/stable/ClutterFixedLayout.html
you can also use ClutterGroup, and use constraints to maintain a layout:
http://developer.gnome.org/clutter/stable/ClutterConstraint.html
It has been a while since I have used clutter but I will try to provide some insights. As the error says you cannot cast ClutterTexture to ClutterContainer. You can add actors only to container actors. If you want to setup background one of the options could be stacking of actors. You can stack other actors on top of the actor with background texture using layout managers. This link provides some details which I think can be useful in your case.
Hope this helps!

Stuck at a trivial problem in Grails 3.1.5: Show the fields of a domain object, excluding one of them, including a transient property. Yes, this is my first Grails 3 project after many years with previous versions.
The generated show.gsp contains
<f:display bean="rfaPdffile"/>
This will include a field that may contain megabytes of XML. It should never be shown interactively. The display: false constraint is no longer in the docs, and seems to be silenty ignored.
Next I tried explicitly naming the fields:
<f:with bean="rfaPdffile">
<f:display property='fileName'/>
<f:display property='pageCount'/>
...
</f:with>
This version suprisingly displays the values without any markup whatsoever. Changing display to field,
<f:with bean="rfaPdffile">
<f:field property='fileName'/>
<f:field property='pageCount'/>
...
</f:with>
sort of works, but shows editable values. So does f:all.
In addition I tried adding other attributes to f:display: properties (like in f:table), except (like in f:all). I note in passing that those two attributes have different syntax for similar purposes.
In the Field plugin docs my use case is explicitly mentioned as a design goal. I must have missed something obvious.
My aim is to quickly throw together a prototype gui, postponing the details until later. Clues are greatly appreciated
If I understood you correctly, you want to have all bean properties included in the gsp but the one with the "megabytes of XML" should not be displayed to the user?
If that is the case you can do:
f:with bean="beanName"
f:field property="firstPropertyName"
f:field property="secondPropertyName"
And the one you don't wish to display:
g:hiddenField name="propertyName" value="${beanName.propertyName?}"
f:with
So list all the properties as f:field or f:display and put the one you don't wish to display in a g:hiddenField Grails tag
You can also try:
f:field property="propertyName"
widget-hidden="true"
but the Label is not hidden in this case.
Hope it helps
My own answer: "use the force, read the source". The f:display tag has two rather obvious bugs. I will submit a pull request as soon as I can.
Bugs aside, the documentation does not mention that the plugin may pick up the "scaffold" static property from the domain, if it has one. Its value should be a map. Its "exclude" key may define a list of property names (List of String) to be excluded. This probably works already for the "f:all" tag; bug correction is needed for the "f:display" tag.
My subjective impression is that the fields plugin is in a tight spot. It is intertwined with the Grails architecture, making it sensitive to changes in Grails internals. It is also required by the standard scaffolding plugin, making it very visible. Thus it needs constant attention from maintainers, a position not to be envied. Even now conventions for default constraints seem to have changed somewhere between Grails 3.0.9 and 3.1.7.
Performance of the fields plugin is sensitive to the total number of plugins in the app where it is used. It searches all plugins dynamically for templates.
For the wish list I would prefer stricter tag naming. The main tags should be verbs. There are two main actions, show and edit. For each action there are two main variants, single bean or multiple beans.
My answer is that at present (2 March 2017) there is no answer. I have searched the Net high and low. For the index (list) and create and edit views, the fields plugin works well enough. A certain field can be easily excluded from the create and edit views, relatively easily from the list view (by listing those that should show), and in no way I could find from the show view. This is such a common need that one would suspect it will be addressed soon. Also, easily showing derived values in the show view, like 'total' for an invoice. One can do that by adding an ordered list with a list item showing the value below the generated ordered list of values, but that is kind of a hack.
In some ways, the old way was easier. Yes, it generated long views, but they were generated and didn't have to be done by the programmer - just custom touches here and there.
I'm trying to convert the Adjuster example mentioned here: http://agiletoolkit.org/learn/understand/view/interactive
into a View that is able to show me the next/previous picture of a list of given images.
I guess the number in the example could be an index into an array of pictures.
I'm just not sure how to provide the list of pictures, when all the code is put in init() for the View, so no way to give it the picturelist before that...
Should I use memorize/recall for this list also to prevent it getting lost upon reload ?
is there another example that might help me?
I think you what you are doing can be much easier done with a classic JavaScript Lightbox script. You would supply it list of images and it would show one full-screen.
If not, you can use this:
https://gist.github.com/romaninsh/7217119
This will give you slides similar to the ones on http://agiletech.ie/
Be advised that this code is a little old.
First time poster here, I'm a designer not skilled at all with php and I have a small issue I don't seem to be able to solve. I'm making a site in drupal 7 using a sub theme on zen.
Btw this is a great CMS, even though people say it's really more a developers CMS. I have no trouble to do what I need using views, rules, display suite etc. So a big thank you for all the developers out there making this such a good CMS. But for this apparently simple problem... no module will help me (I think) and I'm kinda stuck.
So here it is: I'd like to add a subtitle next to the title in all my pages.
So what I did was to add a custom field into the content type basic page (machine name: field_sub_title) which is a simple text field.
I uncommented the following line in my template.php
function mytheme_preprocess_page(&$variables, $hook) {
$variables['sub_title'] = t('field_sub_title');
}
Now my question is how do I load the content of my custom field into that variable?
I know i need to change the second part, but I don't have a clue as into what I need to change this.
Displaying the variable into the the page.tpl.php is something I know about so I only need help with the first part.
{EDIT}
Ok I found how to do this :)
I was looking for a solution in the wrong place. I don't need to change any thing in the template.php file.
Just needed to add this bit of code into my page.tpl.php:
<?php
print $node->field_sub_title['und'][0]['value'];
?>
So I'm posting this here for other Drupal newbies struggling with this....
Your solution may work for now, but there may be a more Drupal-y way to handle a problem like this. If you haven't noticed any problems yet, you may find one or more of the following issues down the road:
Someone who doesn't know php or Drupal theming may need to change the way this works.
If you're like me, you may forget where exactly in code this was implemented.
You may see superfluous markup and/or errors on nodes (content) that do not have this sub-title field (ie. event content not having a sub-title field while basic pages and news articles do).
When you add a field to a content type, it will automatically appear anytime content in that content type is displayed. You should be able to add the sub-title field for your page, event or whatever else you need and have it automatically appear in the markup.
You can 'manage display' of a content type to drag and drop the order for fields to appear. You could take it a step further by using a module like Display Suite to add formatting or layout per-content type.
If you feel like this isn't good enough and the markup for the subtitle must be at the same level as the page title (which is rare), at least add an if statement to make your code check to see if the variable is present before trying to print it. I'd also add a new variable and comments for code readability.
<?php
$subtitle = $node->field_sub_title['und'][0]['value'];
if($subtitle){
print $subtitle;
}
?>
Consider using field_get_items or field_view_value, or at least use the LANGUAGE_NONE constant instead of 'und'
See https://api.drupal.org/api/drupal/modules%21field%21field.module/function/field_get_items/7 and https://api.drupal.org/api/drupal/modules!field!field.module/function/field_view_value/7
This has the added benefit of reducing the number of potential security holes you create.
I'm Currently working on a scene and i cant seem to find infomation as to how to make a setting for my scen. Its basically a street with buildings on either sides. about 500m long.
I want to put it into a city "enviroment" for animation. Also there will be camera movements so i dont think simply adding an image as a background will work. what i want to know is, Is there a a way to achieve what i want without actually building a small city?
any help or a pointer in the right direction would be great.
thanks in advance
A cubemap might work. http://wiki.polycount.com/CubeMap
There are applications which will generate a city for you, based on criteria you enter. You can enter the building types, sizes etc. I've used one called City Engine - I used the built in wizards to create this but you can create one from scratch even specifying the road layouts: Youtube Video

I have a set of names (first, last, salutation) and need a control to allow users to select a single name using WinForms. A ComboBox works fine if the there are ~20 names, but not so well when there are >100 names.
Can anyone recommend a name picker? Perhaps an address book control that I could customize? It's not too hard to write my own, but I have other wheels to invent.
I'm giving you an answer that seems more like a feature request... :-) It can be very easy to use if you implement a control which behaviour is similar to the auto-completion feature of Google: foreach char inserted by the user, a window appears with only the names that match with the string inserted.
I think that it isn't so hard to implement, but I'm sorry, I can't give you a recommendation, only an advice :-)
I agree with Maurizio. To add to his answer:
The most commonly used interface which does exactly this is in email clients, where they auto-complete names (and/or email addresses) as you type them. Thunderbird is a pretty good example. These usually either auto-complete if there is only one match, or show a drop-down list of possible autocompletions you can pick from. In addition, a button next to the field usually allows you to browse the address book as a list.
I'd also suggest filtering the autocompletions available in the most useful ways: e.g. As you type "wi", you could filter it down to names like "[WI]lson, John", "Amery, [WI]lliam", and "[I]ving, [W]alter", making it easy to find people by their initials as well as first and surnames.
