From ab7de41c7bdab22c408aa25713b445d288f3aa50 Mon Sep 17 00:00:00 2001 From: Andreas Kling Date: Sun, 10 May 2020 15:57:45 +0200 Subject: [PATCH] LibVT: Don't commit to opening a hyperlink until mouseup It felt too rushed to open links when simply mousedown'ing on them. Improve this by implementing basic "click" semantics instead. This patch also introduces the ability to prevent link opening if you want to force selection instead. Hold shift and we will not open links. --- Libraries/LibVT/TerminalWidget.cpp | 58 ++++++++++++++++++++++++------ Libraries/LibVT/TerminalWidget.h | 3 ++ 2 files changed, 50 insertions(+), 11 deletions(-) diff --git a/Libraries/LibVT/TerminalWidget.cpp b/Libraries/LibVT/TerminalWidget.cpp index 402ce83eaf..bbb73681f8 100644 --- a/Libraries/LibVT/TerminalWidget.cpp +++ b/Libraries/LibVT/TerminalWidget.cpp @@ -388,12 +388,28 @@ void TerminalWidget::paint_event(GUI::PaintEvent& event) painter.clear_rect(cell_rect, color_from_rgb(should_reverse_fill_for_cursor_or_selection ?
