Author	SHA1	Message	Date
Matthias Clasen	463dffe48d	constraint solver: Fix repeat suggestions We were not storing the previous value, causing the first two suggestions to work, but not later ones. Fixes the test added in the previous commit.	2019-06-28 16:59:39 +00:00
Matthias Clasen	d42c26b117	Amend a constraint solver test Make the 'repeat edit' test make more than to suggestions in a single edit phase. It turns out that this does not work, whereas just doing two in a row does.	2019-06-28 16:36:46 +00:00
Matthias Clasen	12d45c01b0	Add an interactive constraints demo	2019-06-28 13:11:22 +01:00
Matthias Clasen	fc3f4aafe5	Make the constraints demo more interesting Add a max size to the buttons, to force the space to open up.	2019-06-28 13:11:22 +01:00
Matthias Clasen	ffd8b19a87	Add GtkConstraintGuide This is meant to be a flexible space.	2019-06-28 13:11:22 +01:00
Emmanuele Bassi	20c4a4bb21	Use generic pointers for constraint targets Since GtkWidget implements GtkConstraintTarget, we can omit the explicit cast, and validate the type at run time.	2019-06-28 13:11:22 +01:00
Matthias Clasen	f8647b02eb	Redefine constraints with GtkConstraintTarget This is in preparation for allowing non-widgets to act as constraint targets.	2019-06-28 13:11:22 +01:00
Matthias Clasen	4b11e73be6	widget: Implement GtkConstraintTarget	2019-06-28 13:11:22 +01:00
Matthias Clasen	4de3e99fbe	Add GtkConstraintTarget This is an marker interface that we will use to accept other things that widgets in constraints.	2019-06-28 13:11:22 +01:00
Emmanuele Bassi	c81e04755d	Notify a layout change when adding and removing constraints Changing the set of constraints should cause a relayout.	2019-06-28 13:11:22 +01:00
Emmanuele Bassi	e4466dd4fe	Fix the opposite size measurement in GtkConstraintLayout We cannot use the given "for size" when querying our children, because the constraint layout has no idea about the opposite size of its children until the layout is complete. Additionally, we should only suggest an opposite size for the layout if we have one, instead of suggesting a weak zero size.	2019-06-28 13:11:22 +01:00
Emmanuele Bassi	19e7d412e3	Remove size constraints from ConstraintLayoutChild The size constraints are transient to measurement and allocation, so they don't really need to be stored inside the GtkLayoutChild subclass created by a GtkConstraintLayout.	2019-06-27 17:38:02 +01:00
Matthias Clasen	80c27061c6	constraints: Make internal consistency required The relations between left, right, width and top, bottom, height are required for internal consistency. It doesn't make sense to ever drop these. Changing the strength of these relations makes my systems behave much more stable.	2019-06-27 17:38:02 +01:00
Matthias Clasen	bd5c558646	Add gtk_constraint_layout_remove_constraint Otherwise, you can't do many interesting things.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	ad40630008	Do not release reference on the subject of an expression We don't own the reference in the first place.	2019-06-27 17:38:02 +01:00
Matthias Clasen	f07ba4ac5b	constraints solver: Avoid critials When the solver is finalized with existing constraints, we end up with criticals when the constraints ref finalize code calls back into the hash table. Avoid that by emptying the hash table beforehand.	2019-06-27 17:38:02 +01:00
Matthias Clasen	391add73ec	constraint solver: Fix thawing There was an obviously wrong precondition here.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	a21562f270	Do not leak LayoutChild instances Since the LayoutManager owns the LayoutChild it creates, it's also responsible for mopping them up.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	124607d1e8	Add GtkConstraintLayout demo	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	9756cb9482	Add GtkConstraintLayout A layout manager using GtkConstraintSolver to measure and allocate children.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	92f93a603b	Propagate rooting and unrooting widgets to layout managers Layout managers may need to get access to data attached to the root of a scene graph.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	e7cd3d4633	window: Create a GtkConstraintSolver Implement the GtkRoot getter for GtkConstraintSolver.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	5780ec4bf1	Assign a GtkConstraintSolver to each GtkRoot Constraints need to work across different parents, so it's better to have a single constraint solver per top level.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	ec14c1f605	Move the Root interface to a private header We don't expect out of tree implementations of GtkRoot, and having the interface structure private to the GTK code allows us to add virtual functions involving private types.	2019-06-27 17:38:02 +01:00
Emmanuele Bassi	c09fada79e	Add constraint solver GtkConstraintSolver is an implementation of the Cassowary constraint solving algorithm: http://constraints.cs.washington.edu/cassowary/ The Cassowary method allows to incrementally solve a tableau of linear equations, in the form of: x = y × coefficient + constant with different weights, or strengths, applied to each one. These equations can be used to describe constraints applied to a layout of UI elements, which allows layout managers using the Cassowary method to quickly, and efficiently, lay out widgets in complex relations between themselves and their parent container.	2019-06-27 17:38:02 +01:00
