用一些颜色突出显示活动窗口中的选定行 c#(notepad++ 插件)

Question

您好，我正在使用 c# 做一个 notepad++ 插件

我需要的是，以某种颜色显示给定行号之间的活动窗口。假设我有第 2 行和第 8 行，那么它必须以绿色突出显示第 2 行和第 8 行之间的记事本++ 屏幕。

从活动窗口读取

        int length = (int)Win32.SendMessage(GetCurrentScintilla(), SciMsg.SCI_GETLENGTH, 0, 0);
        IntPtr ptrToText = Marshal.AllocHGlobal(length + 10);
        Win32.SendMessage(GetCurrentScintilla(), SciMsg.SCI_GETTEXT, length+10, ptrToText);
        String InputFromActiveWindow = Marshal.PtrToStringAnsi(ptrToText);

聚焦选定行的代码

       Win32.SendMessage(curScintilla, SciMsg.SCI_ENSUREVISIBLE, lineNumber, 0);
        Win32.SendMessage(curScintilla, SciMsg.SCI_GOTOLINE, lineNumber, 0);
        Win32.SendMessage(curScintilla, SciMsg.SCI_GRABFOCUS, 0, 0);
        Win32.SendMessage(curScintilla, SciMsg.SCI_GRABFOCUS, 0, 0);

//答案是

win32.SendMessage(PluginBase.nppData._scintillaMainHandle, SciMsg.SCI_MARKERDEFINE, 1, (int)SciMsg.SC_MARK_BACKGROUND);
            Win32.SendMessage(PluginBase.nppData._scintillaMainHandle, SciMsg.SCI_MARKERSETBACK, 1, 0x99FF00);
            for (int linetobeHighlighted = StartLine; linetobeHighlighted <= EndLine; linetobeHighlighted++)
            {
                Win32.SendMessage(PluginBase.nppData._scintillaMainHandle, SciMsg.SCI_MARKERADD, linetobeHighlighted, 1);
            }

Answer 1

要突出显示选定的文本，请使用

Win32.SendMessage(PluginBase.GetCurrentScintilla(),
              SciMsg.SCI_SETSELBACK, 1, 0xFFFF00);
