你好,我创建简单的Java编辑器简单的Java编辑器GUI
我创建菜单的GUI代码,但我需要匹配 文件:新建:创建一个新的文件。询问文件的名称(以及公共类)以及它将被存储的目录。将创建的文件插入公共类的结构中,例如公共类MyClass {}。
打开:打开源代码为java(.java)的文件。 保存:将当前片段保存在创建期间建立的同一个文件中。 另存为:显示您请求文件名称的对话框以及存储文件的目录格式。格式将是java文件(.java)。该窗口的主要部分将使用户使用编辑器来编辑文件源Java。
窗口的主要部分将有编辑器供用户用来编辑文件源Java。这将一个片段的处理过程中被更新的信息:数字线的数目在Java源代码
格式化文本保留字
每个文件都将打开格式化并在下面的规则来处理时将格式化:该java的保留字将以蓝色显示。 的意见会显示在绿色 字符串文字橙色 所有其他与黑色 的字体将成为快递字体大小12磅
我会提供GUI代码有人能帮助我与上面?
问候 安东尼
