焦点偶尔有误

[Jial08]

系统版本
manjaro20.0.3
idea版本
2020.2

您好，有时候在使用过程中会出现焦点定位有误的问题，在代码编辑区不能删除和回车，用方向键控制移动，焦点的移动实际不是在代码区，而是在项目左侧的文件列表区；还有markdown文件没有预览了，感谢作者的无私付出，现在使用大题没问题了，还望作者查看下这个问题的根源，再次感谢！

不好意思，刚看到，我一般会关注csdn上提问，不太注意这里，markdown 没有预览是因为jetbrainsruntime 使用的jdk11，而它没有把JavaFX 编译进jdk， markdown模块恰恰需要javafx，我后续会写一个jdk11如何整合javafx模块的教程，因为这里有一些坑，另外，.在代码编辑区不能删除和回车，用方向键控制移动，焦点的移动实际不是在代码区，而是在项目左侧的文件列表区 ，具体是如何操作的，能否把复现的操作方式详细告诉我， 另外 ，你的fcitx 用的什么版本，以及用的什么输入法，我争取复现你说的问题，否则我不好调试

[Jial08]

您好：
fcitx version: 4.2.9.8
aur/fcitx-sogoupinyin 2.3.1.0112-1 (+100 0.04)
编译的 jb11_0_7-b944 分支，跟 idea 2020.2 保持一个版本；
其实这个问题在 idea 偶尔复现，就是偶尔切到其它项目再切回来就不能删除代码和回车了，用键盘移动光标，项目左侧文件列表区会显示选中并移动，在 DataGrip 大概率复现，连接一个数据库，选中一个表右键 Modify Table...，对具体某一列删除操作的时候没反应，如下图所示

“切换项目” 这个操作我不太明白， datagrip 的 问题 我会 本地测试并作出改正。

您好，就是 Alt+Tab 操作^_^

您好，就是 Alt+Tab 操作^_^

如果，你着急用，可以改一处地方，在这个类/.../JetBrainsRuntime/src/java.desktop/unix/classes/sun/awt/X11/XInputMethod.java的 getOffXYRelateToFrame 方法：
// Point2D.Double.Double pd = (Point2D.Double)point.get(locations[0]); //注释掉这三行，并添加下面三行，然后重新编译
// caret_x = (int)pd.x;
// caret_y = (int)pd.y;

Point2D pd = (Point2D)point.get(locations[0]);
caret_x = (int)pd.getX();
caret_y = (int)pd.getY();

另外，
我用的kde桌面，你那个切换项目，我这是切换不同的应用程序，搞不出你那个操作，你可以通过终端启动idea，或datagrid，然后正常操作，如果出现bug，一般终端会用error报错，如果有，你可以发给我，向上面那个错误就有类型转化的报错

[Jial08]

我的是 xfce 桌面，可能我表述有误，我也是切换应用程序，按照您说的操作后再编译确实有效，如果再有问题，我会把具体日志贴出来的，感谢！

@Jial08 能否请教下你是如何编译的，类似libx11-dev libxext-dev libxrender-dev libxtst-dev libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev 这些依赖库我在manjaro下找不到

[Jial08]

@dejin0916 我是用的 docker 装载的 Ubuntu20.04 编译的，具体可以参考我的两篇文章
Docker 日常使用
manjaro xfce 环境配置

[ShadowBrook]

@Jial08 十分感谢

[ferstar]

我也有一样的问题，删除操作也是无效

ping @prehonor 大神牛逼，这个patch是不是可以以 contributor的身份提交给JDK team呢？您如果能给JDK打这个补丁。相信全球用户都可以从中受益。
