This PR fixes the issue that the initial column autosizing is wrong under some circumstances. The following things will break the initial autosizing: - Bold Column text (that is where I initially found this problem) - Another font / font size - Graphic
The reason is actually quite simple: The CSS is not (yet) applied initially, we therefore ALWAYS take the default font into account + the graphic is not yet layouted as well. It was not so easy to write tests for this, also for me the `test_resizeColumnToFitContentHeader` is always failing locally. I don't know what happens here, but he seems to not find a (Stub?) `Font` for me. The test I wrote now is checking if the css is applied after we triggered the autosize, which is what we would expect here since we measure text. I also copied the `TableColumnHeaderTest` and rewrote the tests for `TreeTableView` as well, so we can catch any errors here as well since they both use different code (although it is technically the same - C&P errors can happen very easy). ------------- Commit messages: - JDK-8186188: TableColumHeader: initial auto-size broken if has graphic Changes: https://git.openjdk.org/jfx/pull/1405/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1405&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8186188 Stats: 372 lines in 4 files changed: 369 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jfx/pull/1405.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1405/head:pull/1405 PR: https://git.openjdk.org/jfx/pull/1405
