EclipseIDE的Java命令行参数

Question

我已经从Eclipse4.4.2更新到4.7.3，新版本看起来比旧版本（字体和图形）更大。我已经在Windows中“放大”了我的分辨率，但这从未对Eclipse产生影响。我知道Java9（及更高版本）“包括”Windows升级，但我使用的是Java8。Eclipse的新版本似乎受到Windows升级的影响

是否可以使用命令行参数-Dsun启动Eclipse。java2d。uiScale=1.0以抑制新的缩放？ 我曾尝试在eclipse开始时设置此参数，但以下操作不起作用：

eclipse.exe -vm -Dsun.java2d.uiScale=1.0 C:\jdk1.8.0_172\bin\javaw -vmargs -Xms1024m -Xmx1024m
eclipse.exe -Dsun.java2d.uiScale=1.0 -vm C:\jdk1.8.0_172\bin\javaw -vmargs -Xms1024m -Xmx1024m

我搜索了很多，但只找到了如何从eclipse应用程序（运行菜单）修改命令行参数的描述，但我不想设置应用程序的运行选项。我想从eclipse本身设置开始选项

是否可以应用参数-Dsun。java2d。Eclipse IDE上的uiScale=1.0

Answer 1

EclipseUI使用SWT，因此java2d设置不相关

swt.autoScale环境变量控制SWT缩放。这方面的JavaDoc说：

System property that controls the autoScale functionality.

• false: deviceZoom is set to 100%
• integer: deviceZoom depends on the current display resolution, but only uses integer multiples of 100%. The detected native zoom is generally rounded down (e.g. at 150%, will use 100%), unless close to the next integer multiple (currently at 175%, will use 200%).
• integer200: like integer, but the maximal zoom level is 200%.
• quarter: deviceZoom depends on the current display resolution, but only uses integer multiples of 25%. The detected native zoom is rounded to the closest permissible value.
• exact: deviceZoom uses the native zoom (with 1% as minimal step).
• <value>: deviceZoom uses the given integer value in percent as zoom level.

The current default is "integer200".

所以-Dswt.autoScale=xxxxx是您使用的
