i'm facing one problem about attaching movieclip from loaded movie, so basically we have a Map
Map.loadMovie("SimpleMap.swf");
in this map there's a npc dialogue with its name "Dialogue1" I want to attach it to the client. It should be basically something like
_root.attachMovie("Map.Dialogue1", "dialogue", _root.getNextHighestDepth());
but it seems I can't get it to work. Anyone can help?
Note: Also I want to attach the movieclip to the client instead of the map, else I would use Map.attachMovie
it's been a while since I wrote any Actionscript 2 stuff, but have you tried removing the quotes around Map.Dialogue1 ? - If I remember correctly passing a string would make Flash look for the symbol in the library, not from the global or current scope...
_root.attachMovie(Map.Dialogue1, "dialogue", _root.getNextHighestDepth());
If you want you can import mx.core.UIObject and then use the method _root.createObject() (or if it is O-O use createClassObject()).
It is going to attach the "npc dialog" as an object... you need to specify the linkage name and give the instance a name. So for example if you called the dialog "npc_dialog" in the library then use:
_root.createObject("npc_dialog", "my_npc", _root.getNextHighestDepth());
Here is something else you can try... go to the library and drag a instance of the movie onto the stage somewhere where it will not be seen, like for instance on the next key frame or off the stage then try to run attachMovie().
What happens is flash will compile the clip in the most efficient way possible so if it sees you imported a package but did not use it then it will ignore this class in the compiled clip... so when you go to run and it tries to attach the movie it can't find it.

In a Dolphin smalltalk treeview I'd like to use a custom icon, depending on the state of the item displayed, (differente state, different icon)
How can I do that ?
I cannot really understand how to use a "my" icon.
I've create a class "connection", with an instance variable "connected"
and two class methods "connectedIcon and unconnectedIcon that returns icon images.
Then an instance function "icon" that returns one or the other image based on the connection state.
I can add instances of this class to a tree view and see the name of the connections.
But how to show my Icons ?
I tried to sustitute the getImageBlock of my presenter view with the following expression [:obj | obj icon] but it doesn't work.
(nothing seems to happen).
this is made in my presenter initialize :
initialize
super initialize.
treePresenter view getImageBlock: [:obj | obj icon]
what's wrong with it ?
best regards
Maurizio
When you are editing a TreeView, one of the properties is getImageBlock. By default it is not really a block but another object that understands the message #'value:' (the class IconicListAbstract). You can replace this property with a code block (or other object that understands #'value:') and answer the image you want displayed.
In Microsoft Windows, icons are typically stored in a DLL. You should be able to use an icon explorer or editing tool to see the icons in a dll. For example, get IconExplorer from http://www.mitec.cz/iconex.html and try opening DolphinDR7.dll. Do the icons and numbers match what you see when you return a number in your application?
To determine (or override) the resource library used, see SessionManager>>#'defaultResLibPath'.
Typically, the getImageBlock is set using the property editor in the GUI editor, but setting it through code can work as well.
Wonderful Dolphin Smalltalk!
I had two problems
1) how and where to modify the getImageBlock method of my Treepresenter.
2) where to put the icons ad how to get the imageindex of each icon.
This is the solution :
1) it's not needed.
The treeview sends an #iconImageIndex" message to my model
this is handled by the default method (in the Object class) that send to my object the message #icon
and to the result of this message (an icon) the message #iconIndex.
This message is understood from the icon that answers with its own iconIndex.
So the only method I need to impement is #icon in my class Connection
that I implemented as follows:
icon
opened ifTrue: [^Connection connectedIcon] ifFalse: [^Connection unconnectedIcon]
In the class itself the two icons are imported in the image by evaluating the createIconMethod,
as explained in the blog article 'Beauty with less Beast'.
So my problems are solved.
Thanks to all.
Maurizio.
I defined a class called "FilterCriteria" which has a bunch of function .m files (getAMask, getBMask, etc.) associated with it. When I create the FilterCriteria object and call the functions using it, I don't have any problems. However, recently I added another function (which, on a side note, is almost identical to another function that still works), and Matlab returns the error, "No appropriate method, property, or field getHMask for class FilterCriteria."
I've searched online for this problem, but I can't find anything. The file getHMask.m is definitely in the correct folder, so I don't understand why Matlab seems to have such a problem finding it.
Here's getHMask.m's header:
function mask = getHMask(object, quadrant, channel)
Any help would be greatly appreciated. Thanks in advance.
1) A mistake I make sometimes is not saving the file with the correct name. Make sure capital letters are in the right places etc!
2) Another layer of error checking here... You can call methods('object here') (see here) and make sure it lists the method (function) that you are trying to add to it. If it doesn't show up here you should check into the implementation of the method and make sure it's correctly being added to the class you're using for your object.
I had the same problem that's kind of suggested by Ben's bullet #2 and it was driving me crazy. Turns out MatLab wasn't loading the latest version of my class's m-file. I vaguely remembered it gave me a warning earlier about that, because there were old instances of the class in the workspace and to keep from invalidating them it said it wouldn't update the class until I cleared the workspace...
So if that's the problem, restarting MatLab will work, or you can just enter >> clear
I'm creating an iOS5 app (programmed in Objective-C) which provides a couple of functions. One of them is to allow a user to fill out a text field with JavaScript. When the user presses a "Test" button, I want it to save to a specific JS file and move to a new view, displaying an HTML page that will display the results of that JavaScript on a canvas element.
Unfortunately for me, I have no idea how to save to a JS file for a text field. Nor do I know if this is actually the best way to achieve the results I'm after.
So can anyone tell me the code I'd need to place in the IBAction of my test button to save the file, or if there is a better way to get the user's script into the HTML file with the canvas element?
You have some options to do that.
Add a callback in WebView is possible only in desktop apps, but you can make a workaround.
1- Set a handler to click in javascript;
2- This handler parse the value via windows.location (trying to change the current url);
3- In UIWebviewDelegate set webView:shouldStartLoadWithRequest:navigationType: to recognize this values parsed by javascript and returning NO (canceling the url change).
After you have the code typed by user, is easier pass to the new one UIWebView. You can save the file via NSData or other class and load in by the path, or you can parse directly the code to be showed via NSString.
EDIT
I, still, belive what I said is what you want, but with a little more info. Yes, 3 NSString probably solve your problem. You even can call eval in javascript, via objective-c and parse user code too. Those logic ideas are a good approaching. You can choose the easier for you.
There are more info in this another Q&A
You can use html 5 local storage for that.
I'm using a gtk.Image widget to display a picture in a gtk window. I can set the image to be displayed before I call window.main(), but after I've done that the image won't change any more. Basically:
import pygtk
pygtk.require('2.0')
import gtk
(...)
window= Window()
window.canvas= gtk.Image()
window.window.add(sprite.window.canvas)
window.canvas.show()
window.canvas.set_from_file("pic1.gif")
window.main()
window.canvas.set_from_file("pic2.gif")
pic1.gif will be displayed. Is there a proper way of changing the image (I don't care if I have to use a widget other than gtk.Image)? All I can think of is destroying the window and creating a new one.
Edit:
I realized my mistake... I called window.main() for every window and any window's destroy event called gtk.main_quit(). Had to make slight adjustments, but it works now. Even after calling window.main() :)
As Rawing hasn't yet accepted his own answer, I'll post it to get this off the top of the unanswered questions page, and to help out anyone skimming this from a search engine clickthrough by providing a comprehensive answer. (Rawing, feel free to post your answer yourself, all the same.)
In your code, you're declaring window as Window(), as opposed to gtk.Window. If you're building in one window, you should not need to do this every time. Create the window once, add what you need to it. If you need additional windows, declare them separately in this module, and call them from code (instead of from main).
Furthermore, don't name your objects with a "window." at the beginning...that just gets overly confusing. Give it a simple name, add it where you need it. Python will do the rest.
A cleaned up version of your code above would probably look like this:
window = gtk.Window()
#You may need additional arguments above, such as to make it top level.
canvas = gtk.Image()
window.add(canvas)
canvas.show()
canvas.set_from_file("pic1.gif")
Now, just change the image in an event or another "def", like this:
def ChangePicture():
canvas.set_from_file("pic2.gif")
Canvas should update the picture automatically.
I want to create a new object so as to instantiate and use it several times;
For example, if I want to create an object that has a label and a button inside, how do I? I created a new NSObject but inside it has nothing, then how do I make everything from scratch since there was a viewDidLoad for example (obviously, since it has a view)?
thanks!
Your questions lead me to think that you're really just starting out. There's nothing wrong with that, but rather than trying to summarize several megabytes of documentation in a few paragraphs, I'm just going to point you to the iOS Starting Point. I think that you're just trying to create a container that can hold other UI components? If so, use a UIView for that. However, don't jump in and try to get something specific done without first reading through some of the Getting Started documents -- you'll just end up back here, and we'll just point you back to the docs. You might like the Your First iOS Application guide, as that lets you get your feet wet but explains things along the way.
