forms - 在 oracle 中从另一个表单设置菜单项属性

Question

美好的一天，我正在使用 Oracle Forms Builder 开发一个系统。我有 3 个表单，MAIN、LOGIN 和 REGISTER 以及一个名为 MENU_MAIN 的菜单表单，它附加到 3 个表单，将显示的第一个表单是 MAIN，我禁用了一些按钮，因为用户无法访问，除非它们是注册并登录，现在我的问题是，他们登录后再次提示他们进入主界面，我需要启用禁用的按钮，我该怎么做？我要把代码放在登录名上吗？感谢您的回复

"am i gonna put the code on the LOGIN?"

Well I honestly don't know which other part of your application can know that a user has logged in, so yes, the LOGIN screen has to handle this.

What should it do? It should set a value in a global variable. Your MAIN screen should interrogate the global variable, probably in a When-New-Form-Instance trigger, and set the buttons' properties accordingly.
