From 732581885fbf95f367c3fe7ee8d71e490cc6cfe3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?S=C3=A9rgio=20Martins?= Date: Sun, 25 Sep 2022 22:15:52 +0100 Subject: eglfs: Improve z-order handling In 9ccbbeecbd we've added basic z-order handling, so main window always stacks behind tool windows. After extensive testing we found more basic cases to be handled: - Modal windows go on top - Qt::Popup goes on top of Qt::Tool Fixes: QTBUG-105707 Pick-to: 6.4 Change-Id: I00eba330864c7abc31652226d55f66f4b7f44dc0 Reviewed-by: Laszlo Agocs --- src/opengl/qopenglcompositor.cpp | 22 ++++++++++++++++++---- 1 file changed, 18 insertions(+), 4 deletions(-) (limited to 'src/opengl') diff --git a/src/opengl/qopenglcompositor.cpp b/src/opengl/qopenglcompositor.cpp index 2c2facd4b9..3e1b2aebed 100644 --- a/src/opengl/qopenglcompositor.cpp +++ b/src/opengl/qopenglcompositor.cpp @@ -310,14 +310,28 @@ void QOpenGLCompositor::ensureCorrectZOrder() return true; } - // Case #3: One of the window is a Tool, that goes to front, as done in other QPAs + // Case #3: Modality gets higher Z + if (w1->modality() != Qt::NonModal && w2->modality() == Qt::NonModal) + return false; + + if (w2->modality() != Qt::NonModal && w1->modality() == Qt::NonModal) + return true; + const bool isTool1 = (w1->flags() & Qt::Tool) == Qt::Tool; const bool isTool2 = (w2->flags() & Qt::Tool) == Qt::Tool; - if (isTool1 != isTool2) { + const bool isPurePopup1 = !isTool1 && (w1->flags() & Qt::Popup) == Qt::Popup; + const bool isPurePopup2 = !isTool2 && (w2->flags() & Qt::Popup) == Qt::Popup; + + // Case #4: By pure-popup we mean menus and tooltips.
