原创 error: ‘ui_mainwindow.h‘ file not found（ui头文件未创建）

问题：在刚好创建的Qt Designer Form Class类中，发现类的.cpp文件中有ui头文件未找到原因：.ui文件中还未添加任何控件，导致ui头文件未创建而报错。解决：在.ui文件中，任意添加控件，再讲工程重新构建，就会生成ui头文件，消除报错...

原创有选择功能的下拉框的显示与隐藏

先看运行效果光标定位到按钮处按Enter键，展开下拉框选择成功，隐藏下拉框**在注册界面的doAction()里判断是否触发<角色>按钮，触发则展开，并直接在旁边的空白处显示两个可选按钮（需要新创建一个Window的派生类实现），两个按钮选择其中一个后，调用部分清屏函数，并把选择的结果打印到框中（这个框是死框，单纯由线条打印，不是Edit类）**附上部分代码if(res==3) { //下拉框选择角色 Tool

error: ‘ui_mainwindow.h‘ file not found（ui头文件未创建）
Evan364: 打脑壳，按照你这样弄我没成功，然而不影响运行，后来加了给头文件进去红波浪就消失了
grub rescue：使用boot-repair-disk + Rufus进行grub修复
*0。16: 我最近也在解决这个问题，看见了一个可行的方案：Caught the dreaded "grub_is_lockdown not found" bug. Need Help Resolved Q4OS. Based on Debian. Rebooted to this lovely error. I can get into the grub rescue but don't know what to do in there. Don't know exactly what to put here. Can anyone help guide me through getting my system back? EDIT: FIXED IT Here is what you need to do (For Q4OS or other debian distros): Prerequisites: You need to know what drive/partition your root is on you need a wired connection to the net Know how to make a bootable USB (I am assuming you know how to do this. You did install linux in the first place, right?) A second healthy system Instructions: 1、on a healthy system, go grab the official debian install image https://www.debian.org/distrib/ 2、make a bootable USB 3、Boot up from said usb on the busted system 4、Select "advanced options" and "graphical rescue mode" 5、go through the setup selecting your language, keyboard, etc 6、When you get to the screen "enter rescue mode" first select your root filesystem. Mine was "/dev/sda2". This will not always be true. MAKE SURE you know which drive and partition it is. If not, go googling for how to find out (ls from the grub rescue might be of use) 7、If it asks you to mount a separate "/boot/efi" say "yes" 8、Select the "Reinstall GRUB Bootloader" option 9、When it asks where to install it, use the same root partition you selected above 10、select "reboot the system" If all goes well, your system should reboot normally. This will get you booted but keep in mind you are no longer booting from EFI. Now if someone wants to come along and suggest edits that allows one to fix their EFI boot, then I will modify.
