| * update API to what was agreed on the API review meeting yesterday:Jan-Arve Sæther2009-08-195-313/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes are: * Move enums in QGraphicsAnchorLayout::Edge to Qt::AnchorPoint. Prefix them with Anchor since they are not edges in general. * Rename anchor() to addAnchor() * Rename anchorCorner() -> addCornerAnchors() * Rename anchorWidth() -> addLeftAndRightAnchors() * Rename anchorHeight() -> addTopAndBottomAnchors() * Rename anchorGeometry() -> addAllAnchors() * remove the overloads that take a spacing argument, and add setAnchorSpacing() to accommodate for that. * Added anchorSpacing() (implementation missing) * Added unsetAnchorSpacing(). (implementation missing) * made sizeHint() protected. Updated all examples and autotest to reflect this API change.

| * QGraphicsAnchorLayout: fix calculation of sizeAt* values for SequentialCaio Marcelo de Oliveira Filho2009-08-181-7/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit implements what's described in the previous commit QGraphicsAnchorLayout: fix expected values for parallel test When filling the sizeAt* values (the three points used for interpolation when setting geometry), now sequential anchors distribute the sizes to the children in a fair way, i.e. proportionally in relation to the existing min/pref/max hints. Each value is defined in relation of the pref (either as a shrinkage in pref or a grow in pref). In both cases the shrinking/growing factor is the same for all children. When we implement support for QSizePolicies, this distribution might be changed by setting size policies for a certain item or anchor. This makes two tests work -- so no more expected fail. Also fixed a typo in one test's expected results.
| * QGraphicsAnchorLayout: missing restoreSimplifiedGraph callCaio Marcelo de Oliveira Filho2009-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | When creating an anchor we might have to create the edges for an item if the item is new. In this case both dimensions are affected. The call is clearly missing since createItemEdges() declared this dependency via Q_ASSERT. Patch from Jan-Arve. Reviewed-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When traversing the graph looking for calculating the distances, also enter inside the complex edges to find (and calculate) the distances for the vertices that were simplified. This require a little tweak in the traversal, now we can't always skip an edge when both vertices are already visited, because complex anchors can hide vertices inside (a sequential anchor in practice remove vertices from the full graph). As a bonus we now pass on the 'example' test (as expected) and the example now works fine. Signed-off-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org>

| * QGraphicsAnchorLayout: use a recursive approach for size hintsCaio Marcelo de Oliveira Filho2009-08-142-204/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring back the refreshSizeHints() now that we have locally the necessary information to get the size hints given an arbitrary anchor data. We also created a bit to set whether the AnchorData is an anchor of a layout (i.e. connects the layout with something else) or not. This costs one pointer more in the AnchorData, but simplifies a good deal of code and avoid traversing the graph to get this information back, so I think it's worthwhile.

This information is useful for many functions when working in simplified mode. Changed the name "origin" to "from", and add an "to" field.

| * QGraphicsAnchorLayout: size hint updated in a simplified graphCaio Marcelo de Oliveira Filho2009-08-142-123/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit makes setAnchorSizeHintsFromItems() support a simplified graph. Instead of going recursively, since AnchorData doesn't have all needed information, we make a list with all anchors/vertexpairs with dependencies first. That way we are sure to fill all information, and the group anchors can peek at its children anchors (dependencies) and they'll have updated information. This solutions doesn't require refreshSizeHints(). Alternative solutions that we might consider are: complementing the AnchorData information or making refreshSizeHints() take two AnchorVertex as parameters and use the recursive approach.

| * QGraphicsAnchorLayout: prepare ground for doing less simplificationsCaio Marcelo de Oliveira Filho2009-08-133-15/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add variables to track whether the graph is simplified or not, as well as make the functions that need it simplified/restored call the corresponding functions. The functions look at the state variables, so it's safe to just call them. Also added Q_ASSERT() through the code paths that SHOULD have the full graph (not simplified), for making easy to track bugs in future refactorings. Ironically this commit cause more calls to simplify/restore right now, but the state will be better when we fix some functions to be simplification compatible ;-) Signed-off-by: Caio Marcelo de Oliveira Filho <caio.oliveira@openbossa.org> Reviewed-by: Artur Duque de Souza <artur.souza@openbossa.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In simplification, the preferred size of a parallel group should get the maximum preferred size (and bound it to the maximum size). This follows the principle that for an layout item: 'growing is better than shrinking', and is consistent with what our linear program also do. This patch also make sure that the sizeAt* are properly initialized to the preferred size, the idea is if there's no restriction upon an anchor, it'll keep it's preferred size no matter what.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that if an item had a center anchor and we removed the left-center anchor before we called removeCenterAnchors(). Suppose the center vertex had 3 edges, (refcount was 3) removeAnchor would then *first* remove the left-center edge, causing the internalVertex refcount to go to 2. That would cause removeInternalVertex() to try to "merge" the two center anchors by calling removeCenterAnchors(). Of course, calling removeCenterAnchors at that point did not work since removeCenterAnchors() assumed that the only two edges connected to the center vertex was its internal left-center and center-right anchors. This was not the case, and the assertion Q_ASSERT(first && center && last); was triggered, since first (or last) was removed at that point. Of course it was not enough to simply call removeCenterAnchors first, because that function assumed that the only two anchors connected to the center vertex was "internal center anchors". removeAnchors is a bit special since we are not really interested in first converting the "internal center anchors" to a single internal anchor because the ultimate goal of that function is to remove *all* anchors. The solution was the additional argument "substitute" to indicate that we really just want to substitute with a simpler anchor (normal behaviour). If not, we really just want to delete the center anchors (don't even try to merge them into a simple internal anchor).

| * QGraphicsAnchorLayout: Enable graph simplificationEduardo M. Fleury2009-08-101-18/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables graph simplification in its simplest way, which is to simplify the graph, run simplex and then restore it back. It also adds code to handle cases where the simplification handles the whole graph, and that therefore no simplex needs to be run. Additionally, the updateChildrenSizes() method is called on every root anchor in order to propagate the new sizes down the tree. A know issue appeared after this commit, as the quote below explains: ===== Q_ASSERT error in "Parallel" test That's something that started happening in the Parallel test (tests/auto/qgraphicsanchorlayout) after my commit of today, that enables simplification. I haven't been able to investigate it deeply but that's what I know about it: - It's triggered when the layout is destroyed, more precisely, from within "deleteLayoutEdges". What happens is that the layout structural anchors are missing at that point. - I suspect there's something to do with the simplifyGraph() and/or restoreSimplifyGraph() code. I say that because I tried moving the "restoreSimplifiedGraph" call from the end of the calculateGraph(s) method to the line exactly below the "simplifyGraph()" and the error still happens. That means that simplifying and then immediately restoring the graph might not leave it to the point where it was before the simplification. ==== Signed-off-by: Eduardo M.
