Cappuccino is a comprehensive **framework** for building entire **applications**. It provides a fully integrated stack—including a mature UI library, event handling, and data management—designed for large-scale development. Beyond this, Cappuccino provides a more integrated and powerful data-binding layer inspired directly by Cocoa, which dramatically reduces boilerplate code for complex UIs as you can see in this [example code](https://github.com/daboe01/UIBuilder/tree/master/public/Frontend) that uses these features: @@ -103,19 +122,19 @@ Beyond this, Cappuccino provides a more integrated and powerful data-binding lay * **Advanced Filtering with Predicates:** A table displaying thousands of items can be filtered simply by setting a predicate (a declarative filter rule, e.g., `lastName BEGINSWITH 'S'`) on its controller. The UI updates instantly. This eliminates tons of manual state management and filtering logic code. * **Automatic Value Transformation:** Data can be easily formatted for display (e.g., dates, currency, booleans to "Yes/No") directly within the binding itself using value transformers, keeping model data pure and view logic minimal. -**Q: Can Cappuccino be used on Windows/Linux?** +**Q: Can Cappuccino be used on Windows/Linux?** **A:** Yes. The development tools run on Node.js and are platform-independent. Applications can be developed on any OS and deployed on any web server. -**Q: Is Xcode required?** +**Q: Is Xcode required?** **A:** No. Any code editor can be used.

The `CPWebView` control allows arbitrary HTML/CSS/JS content to be embedded.

These included four types that did not exist: CPUserInterfaceLayoutOrientation, CPLayoutAttribute, CPEdgeInsets, and CPMapTable. The missing types are now present. - Add local typedefs for CPUserInterfaceLayoutOrientation and CPLayoutAttribute. Numeric values match the equivalent Cocoa constants. - Add CPEdgeInsets as an alias for the existing CGInset struct. Add CPEdgeInsetsMake and CPEdgeInsetsEqualToEdgeInsets. - Import Foundation/CPMapTable.j. CPMapTable already exists in Foundation. This commit also fixes two logic errors found during review. - arrangedSubviews did not match the true view order after insert or remove. Add _rebuildArrangedSubviews and call it from every method that changes view order. - Trailing-gravity layout added one extra spacing gap past the last view. This shifted the returned layout boundary. Spacing is now added before each view, not after. This commit adds one new property. - Add a distribution property with storage and accessors. It has no effect on layout yet. This makes the property honest: before this change, the type existed but no property did. The manual test, ./Tests/Manual/CPStackViewTest, used a Narwhal-era Jakefile and would not build. This has been updated to reflect usage under the Node toolchain. This commit adds CPStackView.j to AppKit.j. The file was never imported. Only the build script's wildcard file list included it. This commit adds a header comment to CPStackView.j. The comment states that the class is a placeholder. It lists known limitations. It states that a constraint-solver based replacement is planned. Why: CPStackView must compile and pass tests before capp-build can use this tree as a build reference, and a class with unstated limits invites misuse. --- AppKit/AppKit.j | 1 + AppKit/CPStackView.j | 153 +++++++++++++++++++--- Tests/Manual/CPStackViewTest/Jakefile | 178 ++++++++++++++++++-------- 3 files changed, 259 insertions(+), 73 deletions(-) diff --git a/AppKit/AppKit.j b/AppKit/AppKit.j index edf1dd794..4cd54116c 100644 --- a/AppKit/AppKit.j +++ b/AppKit/AppKit.j @@ -93,6 +93,7 @@ @import "CPSlider.j" @import "CPSound.j" @import "CPSplitView.j" +@import "CPStackView.j" @import "CPStepper.j" @import "CPTableColumn.j" @import "CPTableView.j" diff --git a/AppKit/CPStackView.j b/AppKit/CPStackView.j index c05d776b9..856f9fbaf 100644 --- a/AppKit/CPStackView.j +++ b/AppKit/CPStackView.j @@ -20,7 +20,80 @@ * Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA */ +/* + * PLACEHOLDER IMPLEMENTATION — READ BEFORE USE OR MODIFICATION. + * + * This class lays out views by direct, procedural arithmetic.

This triggered build warnings. This commit adds an import. - Add @import "CPTreeNode.j" to CPOutlineView.j. While addressing this warning, CPTreeNode was audited and found to have an algorithmic complexity regression and multiple structural inconsistencies in the KVO support code. The test suite for CPTreeNode was Spartan in the extreme. All of these have been addressed - see inline notes for details. CPTreeNode is subject to further audit. --- AppKit/CPOutlineView.j | 3 + AppKit/CPTreeNode.j | 357 +++++++++++++++++++++++++++------- Tests/AppKit/CPTreeNodeTest.j | 249 ++++++++++++++++++++++-- 3 files changed, 532 insertions(+), 77 deletions(-) diff --git a/AppKit/CPOutlineView.j b/AppKit/CPOutlineView.j index bf2716fee..8fbd06d38 100644 --- a/AppKit/CPOutlineView.j +++ b/AppKit/CPOutlineView.j @@ -23,6 +23,7 @@ @import "CPButton.j" @import "CPTableColumn.j" @import "CPTableView.j" +@import "CPTreeNode.j" @global CPApp @@ -2531,6 +2532,8 @@ var colorForDisclosureTriangle = function(isSelected, isHighlighted) selector:@selector(outlineViewSelectionDidChange:) name:CPOutlineViewSelectionDidChangeNotification object:aSource]; + + return self; } + (void)unbind:(CPString)aBinding forObject:(id)anObject diff --git a/AppKit/CPTreeNode.j b/AppKit/CPTreeNode.j index f25c83649..b6d31066c 100644 --- a/AppKit/CPTreeNode.j +++ b/AppKit/CPTreeNode.j @@ -17,17 +17,38 @@ * * You should have received a copy of the GNU Lesser General Public * License along with this library; if not, write to the Free Software - * Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + * Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA + * 02110-1301 USA */ @import @import @import +/* + * CPTreeNode implements the NSTreeNode contract. + * The _childNodes array contains only CPTreeNode instances. + * The representedObject property contains the application data. + * The _parentNode and _childNodes properties maintain a strict bidirectional relationship. + * The KVC mutation methods are the public mechanism to change the tree structure. + */ @implementation CPTreeNode : CPObject { - id _representedObject @accessors(property=representedObject); - CPTreeNode _parentNode @accessors(property=parentNode); + /* + * KVO notifications on childNodes and parentNode are not reliable during + * internal structural moves. insertObject:inChildNodesAtIndex: and + * replaceObjectInChildNodesAtIndex:withObject: detach a node from its + * prior position by mutating _childNodes directly, or through + * _removeChildNode:, bypassing the KVC proxy for that step.
