I'm trying to create a custom tab navigator that has to look like. Also, when there's a rollover, the borders of the arrow have to be in blue (like the label in the current tab). For that purpose, I've created a custom component: a hbox containing a label and a canvas with 3 images inside (for the arrow tip that has to change depending on the currentState). Then, I thought of overlapping the components in order to get the blue highlight color (ex: arrow button 3 is over arrow button 4. The image of the arrow tip in button 3 will be transparent outside the arrow, so that we can see the black color of the following button).
I'm now trying to position the components inside the canvas ... but I cannot. After the creationComplete event, I assign the label text and I was calculating the coordonates of the component but it doesn't take into account the label width... -_-'
package custom { import mx.containers.Canvas; public class CustomCanvas extends Canvas { public function CustomCanvas() { super(); [Code] ..... The style borderThickness doesn't apply. Whats wrong with canvas style initialization?
I want to dynamically add different items to thumbContent canvas and use scroller canvas to scroll. I see than the height of thumbContent bigger than 7977 it truncate from scrolling. So - I see the scroller canvas with empty space on top. Then I scroll to bottom - I see the content of thumbContent and at bottom scrolling I see empty space too.
I'm trying to skin a canvas with an image (which is essentially a custom border for the canvas). I've been trying the backgroundImage style as well as the borderSkin style. I can't get the image to scale to the full size of the canvas though. I was wondering what the best way to go about this is.[code]...
I have a component mxml in which i have a save button, on click of the save button i need to display another component which will be in a tab navigator, for this I am using the view stack. My problem is, on click of save I need to display the second tab instead of the first tab, but defaultly the first tab will be displayed.
I am adding a tab navigator to a title window here. Once the title window is closed, it can be reopened using the button.But on opening the title window second time in this manner ,the content of the children of the Tab navigator(here, a label) is not visible.
My problem: I have a tab navigator, with many forms in each tab. But I have a single global save button.Problem is, if I don't open a Tab, it doesn't get initialized and therefore the forms it contains do not exist..
How Can I make it as if the user had clicked on every tab?
This is a general question on optimization technique and am more than willing to rewrite a majority of my code as I am moving a lot of it to a library.My concern applies not so much to flex performance as I have used methods that have reduced cpu/memory footprint so performance is quick when inside a view.The problem I have is with the navigator.pushView which seems slow, I do call my init function on creationComplete for the view but I have it factored so my init looks like:
private function init() : void { doStuff1(); doStuff2();
I I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something.
I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName or a similar method seems to only get me back a TabSkin object.
I realize this is probably a simple question but my google-fu is failing me. I would like to get a windows explorer like file browser to popup when I click a button to select images to upload to my AIR application.However I cannot find a component that handles File exploring. Does anyone know what to use?
I have a flex application mxml file with 3 tabs.the first tab having the link button to select the value in the 3rd tab. Suppose, i have a link button in first atab. And the 3rd tab contains the combobox with values:"basic", "advanced". by default the vaule is displaying "default". When i select the linkbutton on the first tab, the "advanced"should be displayed in the comboBox on the 3rd tab. and the problem is , when click on the first tab link button , at that time the 3rd tab is not initialized. So it is not displaying the "advanced" in the comboBox. selecting the 2nd time on the link button it is displaying fine. But not first time. code: thirdTab.comboBoxId.selectedItem.data = 1;
I have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.
does anyone know how to disable that slide animation and just have the action bar instantly change to whatever action bar the next view contains, but still do a slide navigation for the rest of the view. My Action bar doesn't change on every page so seeing the same image reload repetitively in the action bar.
I am using tab navigator. And it has thee tabs "Search", "Show as text", "Show on map" I have a address search box in Search tab. I would like to hide other two tabs if search has not happened yet. So if user hasn't searched any thing other two tabs shouldn't be visible.
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.
Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window?
Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.
Flex charts, like AreaChart, have wonderful built-in support for displaying data "tool tips" when a user hovers over a point supplied in the data of a graph. You can hover over any of the bar graph examples on this page for a demonstration. I have a graph situation where I optionally draw in some dots as reference points on CartesianDataCanvases supplied to my AreaChart through it's <mx:annotationElements> and <mx:backgroundElements> tags.
I would like to have the same hover data-tip functionality that the AreaChart has, but applied to these dots. I realize that I am just drawing on canvas, and that no actual dataProvider supports these dots, but if there was a way to supply the CartesianDataCanvas with an array of data values or something to that effect,
I'm developing an engine to generate components.I been wanting to get my xml script that read and create a component to be load into 'content' canvas. I not sure how do I get the addChild work correctly as in 'content'.addChild instead of the one shown below:[code]
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?
The basis for the chat window is a canvas. I've got that showing, but how do I make it scroll up? I want to clip the window so only the last 15 lines are shown.[code]...
My code above works absolutely fine, until i resize my browser window to a size below 800px width. When the browser window is make of lesser width than 800px, the canvas with background color #A8A8A8 is on the right of the window, but the problem is, when I move the scroll bar, the canvas should remain on the right of the window. Which does not happen, and that is what my problem is.
How can I solve this issue. What should I do to keep my canvas be on the right=0 all the time.
I'm trying to write some code to an animated images of squares on a Flex Canvas There's something wrong with my code below because it becomes progressively slowerI assume I'm supposed to clear the old squares or something.What am I doing wrong below?:
Basically I want to go to frame2 when the cursor leaves the canvas. The code below contains no errors when tested but it still does not work.
[Code]...
We know that the function gotoAndStop(frame2); works in multiple situations which means the first 3 line is fine. I don't know if the problem is the MOUSE_LEAVE event or this.stage which i suppose is the identifier for the canvas. I sure that there must be an alternative code for the identifier this.stage or the whole code. Any solution on how to fire the given function in the event when the cursor leaves the canvas?
i am required to zoom a canvas through Hslider. The problem is after zooming the canvas i cannot scroll to the extreme left and top of the canvas i.e some part of left and top canvas are not visible. i cannot find the reason. The source code for the example is given below.
Is there a way in Flex by which a disabled canvas looks exactly the same as an enabled canvas? I haven't been able to make sense of disabledOverLayAlpha and disabledColor properties for a Canvas component.
a .fla is 500 x 300. Inside, content moves OUT of the 500 x 300 stage so that it appears like it hides or moves off of the screen. .fla complied... loaded into Flex via SWFLoader:
