GDB调试之TUI界面

阅读更多关于 GDB调试之TUI界面

TUI（TextUser Interface）为GDB调试的文本用户界面，可以方便地显示源代码、汇编和寄存器文本窗口，TUI使用效果如下图所示。 Tui界面可以通过运行gdbtui或gdb-tui命令进入(其它变种gdb也一样，如arm-none-eabi-gdb-tui)，当然也可以进入gdb界面后使用TUI快捷键打开，如C-xC-a快捷键，详见TUI快捷键绑定章节。 1 TUI Overview 在TUI模式中，可以显示以下几个窗口：命令窗口用于GDB调试时的命令输入和命令结果输出显示，与普通GDB窗口无异。源代码窗口用于显示程序源代码，包括当前运行行、中断以中断标识等。汇编窗口显示当前程序的汇编代码。寄存器窗口显示处理器的寄存器内容，当寄存器内容发生改变时会高亮显示。源代码窗口和汇编窗口会高亮显示程序运行位置并以'>'符号标记。有两个特殊标记用于标识断点，第一个标记用于标识断点类型： B 程序至少有一次运行到了该断点 b 程序没有运行到过该断点 H 程序至少有一次运行到了该硬件断点 h 程序没有运行到过该硬件断点第二个标记用于标识断点使能与否: + 断点使能Breakpointis enabled. - 断点被禁用Breakpointis disabled. 当调试程序时，源代码窗口、汇编窗口和寄存器窗口的内容会自动更新。 TUI运行时

At first I tried to override the onScrollChanged method of WebView, and got something but it wasn't as smooth as the desired goal. I noticed in the docs that WebView inherits
