Flash AS3自定義按鈕翻轉(Windows 7風格)

[英]flash AS3 custom button rollover (windows 7 style)

注意: 我選擇保留主題的歷史記錄,因為我認為搜索過程可能對某人有用。 如果您想要解決方案,請轉到我的帖子的底部。

我進行了搜索,但在Google和StackOverflow上都找不到答案(甚至沒有關於它的單個教程)。 我想在Windows 7任務欄之類的按鈕上創建鼠標懸停突出顯示。 高亮顯示移動,並且取決於鼠標在按鈕上的位置。 我不希望按鈕上的任何圖像(僅顏色漸變)保持標准組件。 如何應用此翻轉效果?

返回,我嘗試運行以下代碼:

問題是沒有捕獲任何事件。 我試圖更改click事件上的標簽文本以進行測試,但它根本不起作用(沒有事件句柄)。 真的很奇怪 你能幫忙嗎?

編輯15/11/11我發現我的creationCompleteHandler需要parent.mouseChildren = true; 捕獲鼠標事件。 我放了它,現在我可以看到捕獲了鼠標事件,但是即使刪除狀態轉換並且以visible = true / false進行播放,也不再顯示我的rollovereffect。 鼠標懸停在處理程序上的效果

最后的編輯 ,感謝所有人,我終於找到了解決問題的方法。 我的解決方案:

這里有一些入門步驟:

  1. 創建漸變。 可能:
    • 預定義的圖像
    • 一個圓,填充有設置為透明的外部漸變顏色。 也許需要轉變為橢圓形。
  2. 使用按鈕的區域遮蓋漸變。
  3. 偵聽按鈕區域上的鼠標懸停鼠標懸停事件。 鼠標移動時將漸變的位置更新為鼠標位置(或僅mouse.y )。

我不能保證它會看起來像Windows 7任務欄中的樣子,因為它取決於按鈕的背景和漸變的形狀。 我不確定在那里是否使用了其他效果。 您可以通過添加更多漸變來增加一些透明度,這些漸變會根據鼠標距離而改變其透明度,並嘗試使用多次混合模式 ,可以產生很好的效果。


更新 -我認為this.overEffectRadialGradient.y = event.stageY; 使用錯誤的坐標。 如果按鈕為0,0 ,則可能有效。 本地坐標應該是正確的: event.localY
