如何处理弹出窗口

背景：MPLAB X IDE 4、XC32 V1.44、和声V2.04、PIC32 MZ2064 DAG176、NEWHAVEN 4.3“显示四线电阻触摸屏（ST722T2内部控制器）、内部DDR。我有几个简单的问题。第一个是如何处理弹出窗口。它能像创建窗口一样简单，但是把它放在屏幕的逻辑边界之外，并有一个按钮切换它的坐标，使得它在需要的时候“出现”？我尝试了一个按钮，可以改变它的坐标，结果很甜。第二，有没有限制层到底有多复杂？因为我需要几个配置按钮来弹出几个按钮，它会变得相当复杂。如果它依赖于堆和DDR，那么我对放弃使用单独的屏幕来避免时间惩罚的想法非常有信心。

    Background: MPLAB X IDE 4.00, XC32 v1.44, HARMony v2.04, PIC32MZ2064DAG176, Newhaven 4.3" display with 4-wire resistive touch panel (ST7282T2 internal controller), internal DDR.

I have a couple of simple questions. The first is how to handle a popup window. Can it really be as simple as creating the window, but placing it somewhere outside of the logical boundaries of the screen and having a button toggle its coordinates such that it "appears" when needed? I tried this with a button that could have its coordinates shifted and the results are pretty sweet. Second, are there limits on just how complex a layer can be? Since I need several popups for several of the configuration buttons, it will get fairly complex. If it's dependent on the heap and DDR then I feel pretty confident about ditching the idea of using a separate screen for anything to avoid the time penalty.
