[flexcoders] using system fonts in Flex
AFAIK, any fonts used in Flex have to be compiled into the SWF. Is there some way to use system fonts that are already installed on a customer machine? Specifically, I'd like to build an app that uses Microsoft's new Segoi UI font (included with Vista and Office 2007) without compiling a TTF into my SWF. Thanks, Glenn
Re: [flexcoders] using system fonts in Flex
Thanks for all of the helpful responses. I don't need to rotate the text or do anything exotic with it - just render basic labels. I'm actually trying to avoid embedding fonts in the SWF as I don't have a license to redistribute my preferred font. If I can specify a list of fonts that includes one or more fonts which are already installed on Windows, then that will work fine for my case. Given a use-case involving Flash running in IE7 on a Windows OS, is it safe to assume that device fonts in the context of this thread refers to any font installed on the Windows client machine?

Couldn't it just embed the necessary glyphs from the local font on an as-needed basis? For one thing, you don't generally know at compile time (i.e., when the SWF is being created) what text you're going to render at runtime (i.e., when the SWF is being executed). The data to display often comes from outside, or gets calculated in some way. And even if all the text was set explicitly in MXML or AS, the compiler doesn't understand what those assignment statements are actually doing, as opposed to c = a + b. For another thing, I think with device fonts the Player doesn't just grab glyphs and render them… I think it uses the OS to render them. So if the OS doesn't have rotation APIs, it can't rotate them.

Re: [flexcoders] DataGrid selectAll problem
I've tried setting just selectedIndices - same result In my CheckBoxDataGrid.selectAll() method, I tried calling invalidateProperties/invalidateList/validateNow - same result.

[flexcoders] Re: DataGrid renderering issue - Porting from Flex 2 to Flex 3
FYI - I found the problem - thought I would pass the info along for posterity. My issue was caused by custom header renderers - if every column used a custom renderer, then I would get this problem. Turns out my custom renderers were not setting explicitHeight or measuredHeight, so the mx:DataGrid.calculateHeaderHeight() would end up with a value of 0. Setting a value for measuredHeight on my custom renderer fixed the problem. In the cases where I had some grids that worked correctly, it turns out that they had at least on header renderer that extended mx:Checkbox or mx:DataGridItemRenderer. Apparently those classes return something for measuredHeight. Not sure what changed between Flex 2 and Flex 3.2 to cause this - some bug fix I guess. I've read the excellent blog on item renderers ( http://blogs.adobe.com/aharui/item_renderers/) and other sources about the component lifecycle, but I haven't found a discussion about requirements for custom renderers to set measuredHeight or measuredwidth - can anyonne elaborate on that topic?

[flexcoders] httpservice/save-as question
I already have working code that uses HttpService to send various requests to the backend from my Flex client and process the responses. I also have a customized implementation of the flex DataGrid which implements paging such that the flex client only shows one page of data at a time. The customized control has buttons to issue page forward/backward requests to the backend to get a different page of data. These requests are sent to the backend with HttpService. I have a requirement to save all pages in CSV format on the clients desktop. Prior to flex we had an HTML/Javascript implementation of tables which had the same sort of feature - in that version, the backend would retrieve all of the data, format into csv, and change the content-type on the HTTP response header to text/csv and then setting the content-disposition to attachment, filename=file.csv. The net result was that the browser itself would take care of displaying a dialog that says something like Do you want to open or save this file? I haven't been able to get the same sort of behavior to work with a request generated by the Flash Player. I have my code in the backend modify the HTTP headers in the response to my flex export-to-csv request, but the browser neers displays its open/save dialog - the response always gets directed back to the flash player. Is there a way to make this work? Thanks, Glenn
[flexcoders] error border on custom itemRenderer
I'm having a problem with red borders drawn around a cell in the DataGrid. I have a custom itemRenderer which extends HBox and impements IDropInListItenRenderer In the set data() method, I set errorString based on conditions in the data. The errorString is either set to null or a non-blank string. In the same set data() method, I also call the super class invalidateProperties and invalidateDisplayList methods. For reasons, I don't understand teh parent HBox class does not draw the border when the borderColor is set to errorColor. So I modified the updateDisplayList() method of my custom renderer to say - if ( getStyle(borderColor) == getStyle(errorColor) ) then draw a border myself using the errorColor (defaults to red). So far so good. But I have two problem symptoms: 1. If I correct the error in the underlying data, the red border remains around the cell even though I've verified that my code is NOT drawing it, and the borderColor style is no longer red 2. If I start scrolling around in the grid, other cells without errors are getting a red border. I understand that the grid recycles instances of itemRenderers for performance reasons, so I suspect that fixing root cause of #1 will fix #2. But I'm at a loss as to what to do about #1. Suggestions appreciated. Thanks, Glenn
[flexcoders] FlexUnit, DataGrid and listItems

I'm trying to test my method with FlexUnit, but I can't get listItems populated so the test can't really check anything. In my FlexUnit test, I'm adding the DataGrid instance to a container to get all of it's properties initialized. I'm also adding columns to the DG instance. I'm adding data that maps to those columns. I've tried calling validateNow(), invalidateList() and invalidateDisplayList(), but nothing I've done so far has managed to get listItems populated. Any suggestions on what I can in FlexUnit to get the grid to create item renderers? Thanks, - Glenn
Re: [flexcoders] TextArea popup editor in DataGrid
Getting back to this issue ... As near as I can tell, when the DG gets an exception, DataGrid.focusOutHandler was never called. Instead, calling _popup.setFocus(); in the creationComplete handler for my item-editor triggers a call to itemEditorFocusOutHandler, which ends up calling mx:DataGrid.contains() event.relatedObject which is equal to the UITextField which is owned by the TextField which is owned by my Popup class which is owned by the mx:DataGrid. But itemEditorFocusOutHandler() doesn't call owns() or itemRendererContains(); it just calls contains(). I tried moving the setFocus into the INITIALIZE event handler, but that's apparently too early to setFocus because then I get an exception trying to setFocus. I can't use my own FOCUS_OUT event handler on the item editor to cancel the event when the popup is receiving focus, because FOCUS_OUT is not cancelable. I can't override the DataGrid.itemEditorFocusOutHandler() because it's private. Any other suggestions?

[flexcoders] datagrid crash on horizontal scroll
Hi, I think I may have run into a bug in the DataGrid, but it was hard to tell from the Adobe Issue Navigator because so many of the items that sounded like my problem were imported such that details aren't visible. Hoping someone can give me a workaround or confirmation that this is a known issue (possible fixed in flex 3?) I'm using 2.0.1 hotfix 3. I've got two different crashes, but both have the same sort of symptom - when scrolling to the right as result of a TAB, if the next editable column uses a checkbox as an item renderer, the grid will throw an exception. Both grids have locked columns. In both cases the checkbox column is offscreen initially, but the tab from the rightmost visible column should scroll the checkbox column into view and then set focus on a cell in the checkbox column. In the one case I've tried to debug, it looks like listItems has not been updated to be in sync with horizontalScrollPosition. I've got 3 columns of interest in this scenario: column 6 is editable text, column 7 is non-editable text, column 8 is an editable checkbox. Initially, column 6 has focus and columns 7 8 are not visible. When I tab out of column 6 focus moves to column 8, but DataGrid.itemEditorInstance is not my Checkbox class - it's an instance of DataGridItemRenderer corresponding to the non-editable text in column 7 - as soon as I tab out of column 8, then things go south in itemEditEnd because itemEditorInstance is not really the item-editor. I stepped into createItemEditor - as near as I can tell, the column index is correct, but horizontalScrollPosition and listItems are not in sync with each other. Anybody seen this? Thanks

Re: [flexcoders] TextArea popup editor in DataGrid
I've tried using a popup TextArea but I'm having real problems trying to get it to work as an item editor within a datagrid. My business requirements are - someone can click in the DG cell to start editing. If the cell uses a TextArea control, they should get popup-like TA that extends across rows to enter longer blocks of text - the user can enter data in any text-based editable cell without using a mouse (but they can use a mouse if they want to) - someone can tab across a row in the DG; our DG needs to move from one editable cell to the next (and go to next editable row if they tab out of the last editable cell in a row) - the user can use shift-tab to go to previous editable cell - the user can use ENTER to finish the edit and save the row - the user can use ESCAPE to cancel the edit So I've already got all of the keyboard behavior working with a TextField controls.

Re: [flexcoders] TextArea popup editor in DataGrid
Yes, I don't want the TA to fit within a single Row. You're right - the case for TA at the bottom of a DG is a problem. Today, the TA gets clipped, so that's not good either. The PopupButton doesn't have either problem. How does the PopUpButton popup?

Re: [flexcoders] problem using checkbox in DataGrid
I'll look into that, but our app has a lot riding on item-edit-end, so side-stepping item-edit-end is going to be pretty difficult for me. I was hoping to find some workaround to make sure that item-edit-begin/end is always started.

[flexcoders] focus out of the flash player
I have a requirement to dismiss a dialog if the flash player loses focus (e.g. someone clicks outside of the player). I'm using the Flex 2.0.01 SDK (hotfix 3) with IE 7 and Flash Player 9. I've registered a FOCUS_OUT event handler on the stage. That seems to work, but I've run into a case where the event is ambiguous. I've been keying off of if (event.relatedObject == null) //then assume the player's lost focus. The problem is that if my dialog contains a DropDown and the DropDown is opened, then I'm getting an event that also has a null value for relatedObject. I don't want to close the dialog if someone opens a DropDown :-) I've also tried focus-out handlers on the root and the dialog window objects (my dialog is subsclass of TitleWindow), but they have a similar result. Any suggestions? Is there another sort of event that will tell me when the Player has lost focus to the browser or another app? Thanks, Glenn
Re: [flexcoders] focus out of the flash player
Much better :-) The DEACTIVATE had none of the ambiguity of the FOCUS_OUT. I still had a problem simply closing the dialog when an item-editor was active - seems like there were events still queued which would NPE when they fired after the controls had been deleted. But I worked around that by using the deactivateHandler to raise a flag that told focusOutHandler when it was safe to act.
