  • Creating a bouncing button in flex

    - by Yasmine
    I am trying to make an effect on a button that when I mouse over it, it keeps jumping up and down smoothly and when mouse out it stops. I tried this but the result was really bad: <mx:Sequence id="bounceEffect" repeatCount="0"> <mx:Move duration="2000" yBy="10" easingFunction="{Bounce.easeOut}"/> <mx:Move duration="2000" yBy="-10" easingFunction="{Bounce.easeOut}"/> </mx:Sequence> <mx:Button id="btn" label="Request Information" rollOver="bounceEffect.play([btn])" rollOut="bounceEffect.end()" fillColors="[#ff0000, #ff0000, #ff0000, #ff0000]" color="#ffffff" textRollOverColor="#ffffff" /> Can someone help me on this? There's something else I noticed when I mouse over the button and during the effect the text on the button becomes very hazy. Thanks

  • Making Flex HTML Control UnSelectable

    - by Joshua
    I am displaying some HTML text in an Adobe AIR Application that I do not want the user to be able to cut and paste. How do I make the HTML control disallow highlighting of the HTML without disabling the ScrollBars. mouseChildren=false works but disables the scrollbars which is unacceptable. Right now I have: <mx:HTML location="http://dexter/preview.html" width="100%" height="100%" id="PreviewArea" x="0" y="0" tabEnabled="false" tabChildren="false" focusEnabled="false" focusRect="null"/> But it's not working properly either. I have also tried overlaying a disabled transparent text control over the top of the HTML component, but the user is still able to tab to the HTML and use the keyboard controls to copy the text to the clipboard. Any hints?

  • flex positioning a button within a panel

    - by pfunc
    All I'm trying to do is place a button inside of a panel, rotate that button (so it is vertical) and place it on the edge of the panel. I can;t seem to do this correctly. Here is my code: <mx:Panel id="weekList" width="260" height="100%" x="-500" title="Weeks" > <mx:List id="weekButtonList" width="260" borderVisible="false" contentBackgroundAlpha="0" dataProvider="{_data.mappoints.week.@number}" itemClick="onWeekClick(event);" > <mx:itemRenderer> <mx:Component> <mx:Button buttonMode="true" right="20" width="260" height="50" label="Week {data}" /> </mx:Component> </mx:itemRenderer> </mx:List> <mx:HBox id="closeButtonHolder" rotation="90" width="100" > <mx:Button label="OPEN" click="weekListToggle()" /> </mx:HBox> </mx:Panel> If you look at the part of the script you will see I am trying to rotate it and move it to the left. I am just trying to move it somewhere, and nothing is working. Also, the text seems to dissapear when I rotate it on a 90% axis. Anyone know what I can do for this?

  • Flex component setActualSize

    - by dlots
    I am a little confused about the setActualSize method. It appears from what I've read, that if it is not called on a component by its parent, the component will not be rendered. So it appears that setActualSize is a critical method that is directly bound to rendering the UIComponent. It also appears that the width and height properties of UIComponent override the functionality of the width and height properties of flash.display.DisplayObject, in that they are not directly bound to the rendering of the object but are virtual values that are mainly used by the getExplicitOrMeasured when the parent of the component calls the component's setActualSize method. So the question are: 1) Why isn't the default behavior of every component to just call setActualSize(getExplicitOrMeasuredWidth(),getExplicitOrMeasuredHeight()) on itself? 2) I guess this question stems from the above question and the behavior as I understand it as described above: does setActualSize change the visibility of the component? It appears that that the behavior is that a component is not rendered until setActualSize is called, but if it contains display object children itself (expected behavior as it can calculate measure on itself) and is added to the display list, the only reason why flash isn't rendering it, is because its not visible. 3) Relating to question #1, does updateDisplayList of UIComponent have a method that goes through its children calling setActualSize on each of them?

  • flex button spacing in a horizontal list

    - by pfunc
    How do you dynamically resize buttons in a horizontal list to fit the text size? I am pulling in my button text from xml and it seems that it resizes all the buttons to the first items text. I am wrapping my button inside a canvas, not setting widths for either of them. Basically I need all the buttons to resize to their text, and have them all spaced evenly as well.

  • Accessing children of loaded swf in Flex Image component

    - by pfunc
    I am loading an external swf into an component. It loads everything fine and I can see buttons working in the swf, but I can't seem to figure out how to add children to this swf from the core mxml file. I have tried tracing out all the children of the image component but can't find where or how to do this. This is the image component: <Image id="image" mask="{ maskCanvas }" source="{ _source }" mouseDown="image.startDrag()" visible="{ _source != null &amp;&amp; image.percentLoaded == 100 }" showEffect="{ fadeInEffect }" complete="imageComplete()" doubleClickEnabled="true" doubleClick="onDoubleClick()" /> And in my AS, I am trying to do something like this: myComponent.image.addChild("myMC"); But i either don;t see the clip or there I get an error about not being able to add the child to a ui component.

  • Flex: DateField how to get the value?

    - by Yevgeny
    I' m trying to use the DateField control. I can set the current value using the selectedDate field. Adobe says: "Selecting the currently selected date in the control deselects it, sets the selectedDate property to null", so when user selects other date the selectedDate = null. How do I can get the current selected value? I only saw in the debugger that DateField's text property contains the string with selected date? Do I need to parse it back? 10x in advance yevgeny

  • How should I smooth the transition between these two states in flex/flashbuilder

    - by Joshua
    I have an item in which has two states, best described as open and closed, and they look like this: and And what I'd like to do is is smooth the transition between one state and the other, effectively by interpolating between the two points in a smooth manner (sine) to move the footer/button-block and then fade in the pie chart. However this is apparently beyond me and after wrestling with my inability to do so for an hour+ I'm posting it here :D So my transition block looks as follows <s:transitions> <s:Transition id="TrayTrans" fromState="*" toState="*"> <s:Sequence> <s:Move duration="400" target="{footer}" interpolator="{Sine}"/> <s:Fade duration="300" targets="{body}"/> </s:Sequence> </s:Transition> <s:Transition> <s:Rotate duration="3000" /> </s:Transition> </s:transitions> where {body} refers to the pie chart and {footer} refers to the footer/button-block. However this doesn't work so I don't really know what to do... Additional information which may be beneficial: The body block is always of fixed height (perhaps of use for the Xby variables in some effects?). It needs to work in both directions. Oh and the Sine block is defined above in declarations just as <s:Sine id="Sine">. Additionally! How would I go about setting the pie chart to rotate continually using these transition blocks? (this would occur without the labels on) Or is that the wrong way to go about it as it's not a transition as such? The effect I'm after is one where the pie chart rotates slowly without labels prior to a selection of a button below, but on selection the rotation stops and labels appear... Thanks a lot in advance! And apologies on greyscale, but I can't really decide on a colour scheme. Any suggestions welcome.

  • Flex 3 - Full unicode support fonts and CSS

    - by BS_C3
    Hi! I'm developping a web application that will be used either in Europe or in Asia (specially Japan -Hiragana, Kanji and Katana-, China and Korea). I'm using the following fonts: - ericssonga628.TTF - HelveticaNeueLTStd-Lt.otf - HelveticaNeueLTStd-LtEx.otf - HelveticaNeueLTStd-Bd.otf - HelveticaNeueLTStd-BdEx.otf When I tried to display Japanese characters, I don't get anything. I guess these fonts don't support East Asian characters... Do you know of any equivalent fonts? Also, I was thinking of creating a CSS for each language (or pack of languages) when the user changes the display language. For example, if the user selects "japanese", I'll use the japanese stylesheet. However, how do I switch from a CSS to another? Thanks in advance for your answers. Regards,
