Don’t get it wrong… I am not leaving Flex, most of my current developments still rely on it and I am sure it will last for several more years.

Working with Flex for nearly two years. I am sure I have the right choice however sometimes Flex do makes me mad.

• SWFLoader content can’t be unloaded completely.
  (How many times you try to replace a loader content but you notice the content music never gone away)
• VideoDisplay component doesn’t play .flv correctly…
  Not even those produced by Flash Video Encoder…
• Non standard CSS
• Math.floor (Math.random () * 4) + 6
  (Oh my god… I just want a random integer)
• Smooth scroll List
• Disabling Ctrl key during drag move
• Gradient fill Container
• Full screen Keyboard input…
  (I understand security… but that should be user’s responsibility… not developer’s obstacle) 

• Why can’t I export my syntax coloring settings? 
• I don’t know which part I haven’t done yet… WHERE’S MY TODO!?!?
• Auto building get set function please…

Flex application 有一個特點就係可以完全跳出 web browser o既框架

Adobe AIR 當然係其中一種做法~

但係 Flash player 本身 support full screen mode

所以直接用 full screen mode 就比起 AIR 直接同快喇~!

要用 full screen mode 首先要改動 SWFObject 或者 Object tag

主要係加入 allowFullScreen 呢個 parameter

以 Flex Builder o既 HTML template 為例

SWFObject:

AC_FL_RunContent(
	"src", "${swf}",
	"width", "${width}",
	"height", "${height}",
	"align", "middle",
	"id", "${application}",
	"quality", "high",
	"bgcolor", "${bgcolor}",
	"name", "${application}",
	"allowScriptAccess","sameDomain",
	"type", "application/x-shockwave-flash",
	"pluginspage", "http://www.adobe.com/go/getflashplayer"
);

Object tag: (要留意加左兩個地方~!)

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
id="${application}" width="${width}" height="${height}"
codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
	<param name="movie" value="${swf}.swf" />
	<param name="quality" value="high" />
	<param name="bgcolor" value="${bgcolor}" />
	<param name="allowScriptAccess" value="sameDomain" />
	<param name="allowFullScreen" value="true" />
	<embed src="${swf}.swf" quality="high" bgcolor="${bgcolor}"
		width="${width}" height="${height}" name="${application}" align="middle"
		play="true"
		loop="false"
		quality="high"
		allowScriptAccess="sameDomain"
		allowFullScreen="true"
		type="application/x-shockwave-flash"
		pluginspage="http://www.adobe.com/go/getflashplayer">
	</embed>
</object>

之後 within Flex application 就可以利用 stage.displayState 開動 full screen

stage.displayState = StageDisplayState.FULL_SCREEN;

如果想做到 toggle full screen effect 可以利用簡單既 if… else… statement

if (stage.displayState == StageDisplayState.NORMAL)
{
	stage.displayState = StageDisplayState.FULL_SCREEN;
}
else
{
	stage.displayState = StageDisplayState.NORMAL;
}

但係要留意一點~ Full screen mode o既所有 text field 係唔可以 edit 架…

講真… 咁o既 limitation 可以話將個 application 廢左武功…

暫時都無解決辦法… Astro 都唔得…

Adobe Labs - Flash Player 10 Beta Release Notes

http://labs.adobe.com/technologies/flashplayer10/releasenotes.html

Limited Fullscreen Keyboard Access — In Flash Player 10, key events are supported for non-printing keys such as arrows, shift, enter, tab, space, etc.  Limited access to the keyboard will allow fullScreen games and video controls with keyboard access in a secure way.

背後o既原因係擔心有人 develop 假既 OS login page…

都好無奈… 如果咁既話所有 web browser o既 full screen mode 都應該 disable text input…

Adobe Labs - Talk:Flash Player:9:Update:Full-Screen Mode

http://labs.adobe.com/wiki/index.php/Talk:Flash_Player:9:Update:Full-Screen_Mode#Why_suspend_key_input.3F

When considering this feature, several security concerns impacted our decisions for this first release. The reason keyboard input was blocked was to help prevent phishing attacks using Flash, where full-screen is used to simulate a log-in screen, someone else’s website, etc. This also impacted our decision to add the overlay to visually inform the user that something had changed and they were in a new state.

相信用 Flex Builder 或者 Eclipse 既人都會裝埋 Subclipse
Subclipse 的確令到 project source control 輕鬆好多
但係當你需要做 project folder relocation 或者 project import 就會出現好多問題

舉個例~ 你有一堆 svn 左既 Flex Builder 2 projects 要轉去 Flex Builder 3…
最穩陣既方法相信係 FB2 svn commit 左~ 然後 FB3 checkout 返~
但係如果你選擇 direct copy / project import~
就會有機會出現舊既 .svn data remove 唔到~ 然後無辦法重新 connect svn…

解決方法係人手逐個 .svn delete… =.=||

講笑~ 哈哈

Mac o既 user 會比較幸福~ 因為一句 command 就可以攪掂

[source:css]
find . -name .svn -print0 | xargs -0 rm -rf
[/source]

如果出現 operation not permitted 可以試下加 sudo

[source:css]
find . -name .svn -print0 | xargs -0 sudo rm -rf
[/source]

又幾個月唔打 blog 喇~ 哈哈
想我堅持日日打都幾難~
呢排時間應該鬆少少既~ 打下啦
如果唔係將來就唔知以前做過 d 乜架喇…

呢幾日回顧返以前 d 野先~
(排名不分先後)

之前去完 Las Vegas 應承過 John 要o係香港攪返 d user group 既野
前排忙晒 plagiarism d 野於是就落手落腳去攪~
攪左一次 Adobe Flex 既 workshop 比 CS 既同學~
雖然o個日係平安夜~ 但係都有唔少人捧場~ 大家都好比面~

成個 workshop 分開兩 part
Part 1 講左 Adobe 既 product line
Part 2 就 hands-on 教 Flex 2
(無 Flex Builder… 用 SDK 既日子唔容易過… 成日要睇 doc… 真係唔好意思…)

大家都始乎對 Adobe Flex 可以做到既效果好感興趣
希望真係有好多人寫然後慢慢發展成 user group 啦~

P.S. John 超好人呀~ 3 日就將成大箱 Flex promotion item 寄過黎~ Thanks!

其實應該尋晚 post 出黎~ 不過太夜所以今日先 post
Budget 既問題困擾左成個幾禮拜總算告一段落
所以都正式 register 左 Adobe MAX~

reg 完之後第一件事就係要用佢地 provide 既 scheduler 黎排 session
唔睇都唔知… 差唔多有一百種唔同既 session 可以 reg…
由 acrobat -> breeze -> dreamweaver -> flash -> flex -> xml
再由最簡單既 get started -> intermediate -> advanced
總之就乜都有咁啦~~!! 揀到我傻傻地….
排完之後感覺係…. 仲慘過上堂…. 哈哈~~
當然啦~ 上 Flash-related 既野點都精神好多既~

依家既 schedule 如下

• Combining Flex with PHP and Open Source
• Best Practices for Developing Flash Applications
• Building RIAs with Flex Builder
• Improving ActionScript 3 Performance
• Design Patterns in ActionScript 3
• Understanding Security in Flex and Flash
• User Interface Design with Flash
• Delivering RIA solutions with Cairngorm 2
• Getting Started with Apollo
• Techniques for Integrating Flash contents and Flex applications

其實仲有兩個月~ 所以都仲會有好多變動~~
總之今次就一定係好好既學野機會啦!!
聽朝再講 MAX Event 既 inter-network application
