* QGAL (QSimplex): Make deep copy of constraints inside QSimplexEduardo M. Fleury2009-10-263-12/+13
| | | | | | | | | The idea is to allow QSimplex solver to modify the constraints without breaking other parts of the code that rely on the original ones. Signed-off-by: Eduardo M. Fleury <eduardo.fleury@openbossa.org> Reviewed-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org>

* QGAL: Use constraints of type "equal" for fixed itemsEduardo M. Fleury2009-10-261-12/+22
| | | | | | | | | | | | | | | | We usually create two restrictions for each item, one to tell its size should be more than its minimum size and other enforcing it to be at most its maximum size. Now, for items that have fixed size, ie. minSize == maxSize, we create a single constraint telling its size should be equal its min/maxSize. The immediate advantage is to have one less constraint for each of these items. The indirect advantage is that the simplex solver can take advantage of such information. Signed-off-by: Eduardo M.

* QGAL: clarify the usage of isLayoutAnchor bitCaio Marcelo de Oliveira Filho2009-10-262-11/+4
| | | | | | | | | | | The 'isLayoutAnchor' is necessary only as a way to flag Layout internal anchors, i.e. anchors with the Layout as 'item' in the AnchorData structure. We don't need to propagate this bit when composing anchors. Signed-off-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org> Reviewed-by: Eduardo M. Fleury <eduardo.fleury@openbossa.org>
* QGAL: add orientation bit to the anchorCaio Marcelo de Oliveira Filho2009-10-262-9/+11
| | | | | | | | | Use a free bit in the anchor struct to save the orientation information. That way we do not depend on looking for this information in the vertices (by looking the orientation of its edge).

* QGAL: simplification doesn't depend on vertex anchor point informationCaio Marcelo de Oliveira Filho2009-10-261-4/+4
| | | | | | | | | Look for information inside the anchor instead of on the vertices. This will give us flexibility of simplifying vertices before the anchor simplification phase.

* QGAL: identify unfeasible setups even when graph is simplifiedCaio Marcelo de Oliveira Filho2009-10-262-34/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The calculate graphs now can return early due to unfeasible anchor setups found out during simplification. This allows finding out problems in parallel anchors, when one anchor has maximum size smaller than the minimum size of the other anchor. The order for simplification and refreshing size hints also has been swaped: - First, refresh size hints for all anchors in the graph. If the graph is simplified, the refreshSizeHints() call will reach the children anchors. - Then, if the simplificated graph is invalid, rebuild it. During this rebuild, refreshSizeHints_helper() will be called for all levels. So in both situations we can identify an unfeasible setup. Note that this test alone is not enough to classify the graph as feasible, depending on the graph, it will still need to go through the Simplex. A test case was added and the function that traverse the graph refreshing now is called refreshAllSizeHints(). The old name was not so clear since the function will not fill only the anchors that have items associated. Last but not least, the lastCalculationUsedSimplex variable is cleared when starting calculateGraphs(), since we now can leave the function earlier, without reaching calculateTrunk(), which is the function that sets it.

* Add an extra overload for QMatrix4x4::toTransform()Rhys Weatherley2009-10-254-5/+24
| | | | | | | | | | | | | | Change 100afe8d fixed a bug in QGraphicsRotation related to when the "distance to plane" projection needed to be performed. As a side effect it made the toTransform() API not do the expected thing when the function is called with no argument. This change makes the default no-argument version of toTransform() do the simple "drop row 3 and column 3" orthographic transformation that normal users of the class expect, and adds a new overload for the "distance to plane" projection case for the special case.

| * QWidget painting regression on Windows.Bjørn Erik Nilsen2009-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem occurred on Windows due to a call to repaint() on a top-level window from setDisabledStyle() in qwidget.cpp. This function is called whenever a window is blocking. In this particular case the children of the repainted window are opaque, and should therefore not be repainted, which also means that the top-level have to subtract the region of the opaque children when filling the background. This region is cached, and the problem was that the cached region was wrong. It was wrong because it was not invalidated properly. Task: QTBUG-4245 Reviewed-by: Paul

With many freetype fonts, this resulted in a "spacy" text layout. The necessary fixes on X11 and Windows were to take (positive) leading into account, to make the font database convert point sizes to pixel sizes without rounding to plain integer values, and to subtract the extra pixel from QFontMetrics from the font engines' descent value. The change also fixes several places in styles and widgets, where QFontMetrics::lineSpacing() was wrongly used instead of QFontMetrics::height(). Ideally we should also handle negative leading, which would require additional and bigger code changes in QTextLayout and QPlainTextEdit. In addition, all other editors we have tested seem to ignore leading on X11. If we choose to believe the values provided by freetype, our text layout would be one pixel smaller than everybody else's. On the Mac, this change does nothing. There our layout is still too spacy, and for smaller fonts quite ugly compared to native Mac applications. Done with mae. Reviewed-by: mae
