如何爲此徽標創建嚮導創建動態面板佈局？

我想用3個參數爲以下徽標徽章創建嚮導。我可以使標題動態，但對於圖像和漸變，它是硬編碼的，因爲我看不出如何使它們變爲動態。圖片後的代碼如下：如何爲此徽標創建嚮導創建動態面板佈局？

我還沒有使用繪製方言，所以我對自己在這裏會做些什麼感到困惑。有一些使用* compose *和繪製方言來構建規範的示例，但沒有一個在構建規範後對其進行了修改。也許是在AltME上提出的一個問題。 – HostileFork 2010-05-27 18:27:05

使該塊用於第二佈局的模板。

把你想要有變量，並與（）

渲染時，做一個拷貝/深做一個模板拷貝，然後撰寫/深，以取代從參數屏幕所採取的變量，創建環繞從您的模板副本中進行佈局，並將窗格設置爲新佈局。
