ActionScript 3.0 :: Custom Flex Widget Does Not Scroll
Jun 28, 2011
I have created a custom Flex widget by extending UIComponent that I call FlexMapBuilderWidget. I have overriden the various UIComponent methods for measurement, children, display list, etc.
I used this widget to replace a plain old Sprite so that I could add some layout based functionality. When the Sprite was there, I was able to get scrollbars using:
I have done test output to check the reported size of the FlexMapBuilderWidget in its measure() and updateDisplayList() methods, the size is always reported as a large enough number to require scrollbars.
I would like to create a "component" -- basically a drop-down menu. Except that my drop-down menu will not select an item when a user clicks on it. The user must click on it for 2 seconds and then it will be selected. How can I create this custom widget/component?
Given a few months on my own, I could probably hack something together, but an experts input would be much nicer.This is a custom Google Voice widget/form. I have the backend code, and can share, but right now I need all these pieces to fit together. It is mostly ELSE/IF statements, starting with the first page, and transitioning to the next widget page depending on the data input, correct or incomplete/incorrect as the variables determining which widget page to open.This will definitely take some Flash skills too, but minimally.Currently the SCENE1 page just shows each of the different widget pages and is not meant to represent the final widget - the final widget will be the first page and when clicked transition to a widget/form different page in the same spot, and again, depending on the input.If you want to give it a try, you can download the .FLA here:
FYI: This same widget HAS been sucessfully programmed in AJAX, with it's tons of code and multiple files, but the challenge was to make it work the same way in Flash. This is the very first TRUE custom Google Voice widget - all others I've found are custom icons that when pressed launch Googles GV widget - so this widget is one of a kind! You can view the working widget and download all the AJX components here if you'd like
I am trying to figure out how to embed the Google Voice (GV) code I have been given through my GV account into a Flash web page using Action Script, but instead of using the default GV icon, use my own, which then opens the GV 'Call' interface. Here is the GV code:
I'm trying to create a custom view (one that is not 100% listview, for example), mix and matching images and labels.One issue is that when the label overflows greater than the screen height, the rest just gets off. I had assumed scrolling or touch-drag scrolling would be automatically enabled? How do you enable the touch-drag scrolling that happens naturally in list view?
I want to create a Custom Scroll bar in my FLEX 3.0 application. Which should enable to use Text instead of |||| that shows in ScrollThumb... I have used mx_internal for changing the style of that but still facing the problem that text is not displayed. here is the code that i have created.
I'm having an issue with a custom ItemRenderer I've written for a DataGrid. With this ItemRenderer, it's possible that the contents could exceed the width and height of the DataGrid cell - and when this happens, scroll bars appear, letting me scroll the individual cell.What I would like, however, is that when the contents of the cell are too large, the entire DataGrid scrolls, rather than the individual cells.
Now, when I set the custom ItemRenderer's horizontal and vertical scroll bar policies to "off", I get the vertical scrolling on the DataGrid that I want (the individual cells stretch to accommodate the full height of the contents) but I don't get any horizontal scrolling. Instead, any content too wide for the cell is clipped. Incidentally, setting the DataGrid's horizontal scroll bar policy to "on" has no effect, the scroll bar gutter is drawn, but nothing scrolls Is there a way to force the DataGrid to scroll horizontally when my custom ItemRenderer's contents are too wide for the cell?
I've gotten to chapter 5 in my AS 3.0 classroom book but I need to use wisdom today (CHAPTERS before I gain it for myself),I need to create a custom scroll bar with buttons that function just like the UIScrollBar but more visually suited to our projects. the boss demands it.
I found several tutorials on creating the custom scrollBar, however, they don't include the buttons and I'm unable to find a tutorial on how to create a button scroller (I figured I could link them both to my "info_txt" after creating them separately). how to create an AS3 text scrollBar WITH buttons? how to create a nice scroll effect with buttons(if creating the scroll bar and buttons apart then linking them to the same text field is not possible or a faulty way to accomplish this).
i recently doing a custom scroll bar with mouse wheel,i succes to make it scroll and wheel in internet explorer, but when it come to firefox, it can't wheel but can scroll. I wonder how can i solve this problem.Here is the script ( it actually the tutorial from kirupa, i remember some people have post it before, but i wonder he/she can wheel in firefox.)
scrolling = function () { var scrollHeight:Number = scrollTrack._height; var contentHeight:Number = contentMain._height;[code]....
I want to develop a GWT javascript application that must interact with a flex widget and fire events from 2 directions (flex to GWT and GWT to flex)For example I develop a function in GWT called onWidgetSelected(int widgetID){ ...} the generated javascript code does not contain the name of this function. So If I want to invoke it from flex through javascript call what should I do ?
This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent. dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
I tried to make a very simple dynamic scroll content text box with its scrollbars but my problem is that I wanted its scroll bar to be having a custom look so I was struck over here I wanted the scroll bar should be the only bar without its up and down scroll button
How do I have a standard ScrollBar (or ScrollPane) scroll a custom MovieClip?
Basically, I am creating a custom menu list, and need to have a standard looking scroll bar able to scroll all of the items. If I am making this from scratch, what is the best method? It seems that the ScrollBar component only works with a TextField, and that the ScrollPane only works with importing external images or SWFs. Is there a way to use the ScrollPane to target a MovieClip?
i was under the impression after reading some posts on this forum that the flash mx component scroll bar could be edited and manipulated easily by breaking down the pieces (arrows, bar, ect) and changing color ect as seen fit?( i just was a black scroll handle that is pink on mouseover, and i want to delete the up and down arrows alltogether.)
I'm trying to get my website updated, which normally would not be a big deal, except that during the course of updates, I discovered my site was created using AS1 and now I have to convert to AS3, which seems like a foreign language to me. I'm making progress, except that my latest problem relates to custom buttons.On a couple of my pages I made a static text box into a movie clip and placed it behind a mask. I made custom buttons to fit into the look and feel of my site, which control the "text box movie clip". I don't want to use the generic "UI Scroll" that Flash gives you (even though it's probably the easy way out) because it doesn't fit with my site design.I was given code to use for my buttons, but I get an error when I test my movie.The error I get is an 1120 Error: "Access of Undefined Property" on lines 3 and 14.[code]
i've a tilelist component on my screen which has many entries (more than 10).it displays only 3 items. i've created two buttons for scrolling. right button and left button.if right button is clicked, tilelist component will scroll to next 3 items.likewise if left button is clicked, tilelist component will scroll to previous 3 items.i know it can be done with tileList.scrollToIndex() command.but the problem is, it directly switches to specified number while i want to scroll (tween)..
I'm updating my website and found out that I originally created it using AS1. I now need to update to AS3 and am having difficult time learning AS3 or even catching on to the basics. On two of my pages, I created a static text box, which I turned into a movie clip to have controlled by buttons. I got my down button to work, but I'm still having a problem with my up button. I can get it to work if I use the same code as my "down", but then my movie clip text continue scrolling down, instead of up. Here is my current set up:
Movie clip controller that is 3 frames: Frame 1: stop action Frame 2: blank Frame 3: gotoAndPlay(2);
Looking for an example, of a custom scroll bar inside flash that affects all content? Like, if stage's height goes less than 400, it appears a custom scroll bar, that scrolls all the way through stage's height, up and down!!! with mousewheel function too.
I'm trying to scroll a movie clip with a custom made scroll bar. This is code on the movieclip to be scrolled for the initialization. How this endLimit calculates.
I have a dynamic textbox I would like to scroll. Currently I have 2 images set to scroll up and down with the following actionscript.
[Code]...
The code works fine, though I want when I press, the box to keep scrolling. Currently I have to press, press, press, press, to get a small amount down.
I am making a scroll bar but it doesn't scroll as far as it should. I triple checked all my math but I can't find anything wrong. Probably the code of interest is on the movie clip content0 within the instance whole. This is what actually controlls the scrolling. Most of the other script dictates how the sliders work so you can ignore that, they work fine. Scroll index is a number between 0 and 1 indicating how far down the bar the slider is, 0 it hasnt moved, 1 it is at the bottom. That works as well. So i am not sure why this doesnt work.
I've set-up a custom scroll bar from an on-line tutorial. I have put placeholder text (I have proper text to fill in later) into a static text field that is inside a movie clip on the main timeline which can scroll with as2 however only shows 2/3 of the text. I've tried to see if there is a character limit for the field?
The spark panel component for example can be written like this
<Panel title="Skinny"> <child components ... /> <controlBarGroup> <child control bar components ... /> </controlBarGroup>
[Code]...
The motivation here is that I can now create a couple different skin files to change the look and layout of those subgroups. Reading source of the spark panel, there are some calls within the mx_internal namespace such as getMXMLContent() which is a method of the spark group component, but which I have no access to.
Does the description above make sense? How can I create custom 'contentGroups' in my custom Flex4 component that can use nested mxml child components? Should I approach this a different way?
I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
