image - Theme 在启动时导入图像文件中的所有图像，并通过 netbeans 减慢项目的运行速度。如何避免？

问题描述

很棒的工具，感谢您花费大量时间和精力！我注意到在启动 Designer 时尝试删除未使用的图像：一旦 Designer 启动，但仍在加载主题，我可以选择启动其界面（列表）的“删除未使用的图像”。但是，如果我让主题加载，则删除未使用的图像列表将不会出现。加载主题后，它将填充图像，所有选择器名称都为“import-############”所以主题正在使用这些图像......即使我不打算.我已经在 Gui Builder 中设计了所有的界面布局。如果我删除这些“import-############”文件之一并保存然后尝试运行项目，项目最终会运行（模拟器启动前 10 分钟以上）但不断给出以下信息：警告：使用 EncodedImage.create(InputStream) 加载大图像可能会导致内存问题，请尝试使用 EncodedImage.create(InputStream, int)。如果我启动设计器并允许加载主题（大约 2-3 分钟）并单击保存然后尝试运行项目，那么这个诊断会更进一步，所以什么都不删除，我会收到相同的错误消息。所以在我看来，当我启动 Designer 时，它会导入这些图像，然后导致错误/警告。那么有没有办法避免这种图像导入并删除不需要的图像？相反，如果我不启动 Designer，而是直接在 Netbeans 中运行该项目。我没有收到错误/警告，并且项目在模拟器中启动的速度要快得多。对于这些场景中的每一个，我都复制了一个新的项目文件夹，然后启动了 netbeans。这个文件夹，项目不会有之前启动的设计器。

因此，当我删除图像和两个“theme.res”文件时，项目无法运行并生成以下输出：

当我从“build”文件夹中删除图像和“theme.res”文件时，项目在项目查看器中使用“theme.res”（res）文件启动，项目运行。如果我启动 res 文件并允许它加载主题然后保存并退出设计器，则项目运行。

但是，如果我启动 res 文件并允许它加载主题然后删除未使用的图像之一，保存并退出设计器，“theme.res”文件将从项目查看器中消失。尝试运行项目时，它现在提供以下内容：

未使用的图像文件不在项目文件夹中

解决方案

这永远不会为你工作。

使用 CSS 后，设计器仅对查看生成的文件有用。但是由于 CSS 会重新生成资源文件，因此您所做的任何更改都将被丢弃。您需要从 CSS 图像目录中手动删除不再使用的图像，然后物理删除 res 文件以确保它是从头开始重新生成的。
