> This commit introduces a new client property xawt.mwm_decor_title > implementing JDK-8267307. The property can be set prior to showing a window > or after the window has been displayed, in which case the window will have to > be hidden/shown (re-mapped) for the property to take effect. > > The general idea is to provide control over the "decorations" part of the X11 > window property called _MOTIF_WM_HINTS. Those "decoration" bits are set to 1 > (XWindowAttributesData.AWT_DECOR_ALL) to show all the decorations or 0 > (XWindowAttributesData.AWT_DECOR_NONE) to ask the window manager (WM) not to > decorate with anything, even borders or resize handles. With > xawt.mwm_decor_title property set to "true", this commit adds the ability to > set the bits to 2 (XWindowAttributesData.AWT_DECOR_BORDER), which some WMs > take as "decorate with only a border", thus effectively removing the window's > title bar, but still leaving the resize capability. > > This feature was tested and works correctly on "vanilla" Ubuntu 20.04 with > the "GNOME Shell" window manager. It was also tested with Xfwm4 and KDE, > where it did not have any effect; these two WMs have limited respected for > the "decorations" bits of the _MOTIF_WM_HINTS window property.
Maxim Kartashev has updated the pull request incrementally with one additional commit since the last revision: Changed the check for the XFramePeer target being javax.swing.RootPaneContainer in order to avoid unnecessary class loading if it isn't. Also updated the test such that robot.createScreenCapture() is not executed on EDT. ------------- Changes: - all: https://git.openjdk.java.net/jdk/pull/4113/files - new: https://git.openjdk.java.net/jdk/pull/4113/files/d2586618..da9fbfd8 Webrevs: - full: https://webrevs.openjdk.java.net/?repo=jdk&pr=4113&range=01 - incr: https://webrevs.openjdk.java.net/?repo=jdk&pr=4113&range=00-01 Stats: 8 lines in 2 files changed: 1 ins; 4 del; 3 mod Patch: https://git.openjdk.java.net/jdk/pull/4113.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/4113/head:pull/4113 PR: https://git.openjdk.java.net/jdk/pull/4113
