Without this change, using a traditional scroll wheel mouse with discrete steps would result in very slow scrolling in Firefox.
With this fix we handle these events like in Cocoa: as "[im]preciseScrollingDeltas", which `CPScrollView` in turn knows to apply the configurable line scroll amount for. For backwards compatibility, [event deltaX] and [event deltaY] are premultiplied with a suitable constant, while [event scrollingDeltaX] and [event scrollingDeltaY] show the true values needed.
Browsers other than Firefox seem to always send pixel scrolling information even for old style scrolling devices, at least on the Mac, so are not affected by this change.
Fixes#2013.
Previously when making a paste with a right click caused a crash because the location of the fake event was set to null.
This crash occurs only if the user didn't hit the keyboard yet.
Now, the location of the fake event takes the location of the last event of the app, who is the right click.
This patch fixes a warning thrown by recent versions of Chrome about IE ways of doing. It simply uses aDOMEvent.returnValue if aDOMEvent.preventDefault() and aDOMEvent.cancelBubble if aDOMEvent.stopPropagation are not avavailable
When the Edit menu is used to cut or to paste, Cappuccino needs to do all the work of making it happen. But the current code relied on the browser doing part of the work.
This fix adds new state so CPTextField can know if it should expect the browser to do some of the work or not.
Refs #1964.
This made it impossible to select some (non-editable) text, and then to click a Cappuccino menu option like Edit > Copy. Upon the click of Edit, the just selected text would be lost.
This was caused by some very mysterious code focusing and blurring an input every time propagation was stopped. Since it wasn't documented, the snippet was just removed for now. If it turns out it was useful we'll need to add it back and make sure it's not called in this scenario (while documenting it properly).
Refs #1964.
Like in Cocoa, a non-editable but selectable text can now be clicked and all text can be selected with the Edit > Select All option or the associated keyboard equivalent. Just like in Cocoa this works on selectable text labels as well (text fields without a bezel).
A non-editable text field does not use an input field, and so does not track what is selected within it. We will use a workaround for now but in a CoreText based text field in the future we'd be likely to always have a correct selectedRange and be able to remove this hack.
Fixes#1972.
The platform window is the virtual screen for Cappuccino windows. Per Cocoa, when the screen (platform window) resizes, CPApplicationDidChangeScreenParametersNotification is sent and the CPApplication delegate method applicationDidChangeScreenParameters: is called.
Previously, in IE you could scroll the entire browser window to the right a very long way, leaving white space to the right of the Cappuccino app. This was caused by a 100,000px wide measurement span that was supposed to be positioned at left:-100,000 but was mistakenly at left:-10,000, which left 90,000px on screen.
This commit fixes the left position of that span, eliminating the ability to scroll the app.
Fixes#1725
This change brings nearly all copy and paste related into a single, self-contained class. This new class is still somewhat coupled to CPPlatformWindow+DOM.j in the sense that it's highly specific and meant to be called in a very specialised way. Despite this, it's still a significant decoupling and the new code is more readable and easier to follow.
This change begins to clean up the control flow of copy and paste. Before, copy and paste was dealt with partly in CPPlatformWindow, partly in CPApp and partly in CPTextField.
Now, CPApplication has been removed from the path, simplifying it down to the two more expected actors.
These targets might be rare but could occur in some Cappuccino text editor widget, in which case our standard native paste handling from Safari should work fine.
This fix switches to full native copy and paste in browsers which support it. This allows copy from anywhere - a collection view, a table view and so on - without the browser greying out the copy menu or beeping.
In the future this can easily be extended to copy and paste images as well.
This change also improves Safari paste support. In recent versions of Safari, pasting from the system clipboard into Cappuccino has been impossible. This remains impossible due to the lack of beforepaste events, but now the code cleanly switches to a Cappuccino-only paste at least.
Without this feature, attempts to paste data into a Cappuccino app (outside of a text field) are handled by redirecting the paste into a hidden text field. Then a paste event is generated from whatever is captured in this field after a 0 timeout. This method is prone to timing related bugs where the paste event actually has an empty clipboard.
With this new feature we read the paste data directly from the browser's native paste event when the browser supports it (Chrome 10+, Safari 5+, Firefox 22+). This is much more dependable and may in the future also enable us to read other types of paste data such as images.
When added, level of child window is reset to level of the parent.
A user may change it aftewards to the level that may even break
specified relative position.
E.g. if a child window is added below the parent (Normal)
and its level is set to Floating it will be ordered above.
Whenever you change level of the parent window, levels of the child
windows are reset as well ignoring all your changes.
According to the example, if you set level of the parent to Normal+1,
child window' level will also be set to Normal+1 and its relative
order to the parent (below) will be restored.
Previously, Cappuccino was using preprocessor macros internally for the CGPoint/Size/Rect/Inset/Affine functions, as well as for CPRange. These macros had the same name as the corresponding function, but began with _. The functions were actually defined using the macros.
The motivation behind using macros was to increase performance by reducing function calls. However, there were a number of problems with this approach:
- There was an artificial dichotomy between _CG macros and the corresponding CG functions. We never completely replaced CG function calls with _CG macros. In fact, they were often mixed up in the same file. There was an extra burden on the programmer to remember to use the macro instead of the function.
- If a method call was passed as an argument to a macro, performance could actually be significantly *worse* than a function call. For example, _CGGetRectMakeCopy([view frame]) would expand to `{ origin:{ x:[view frame].origin.x, y:[view frame].origin.y }, size:{ width:[view frame].size.width, height:[view frame].size.height } }`. So instead of a single objj_msgSend and a single simple function call, we ended up with 4 objj_msgSend calls, which are way more expensive than simple function calls.
- Because of this expansion problem, to use macros efficiently required us to remember to use variables for all macro parameters. This didn't happen, and shouldn't have to happen.
- Finally, with modern Javascript engines, function call overhead is so small that it really isn't worth using the macros.
This commit eliminates the _CGGeometry, CGAffineTransformation and CPRange macros and replaces them with function calls.
BREAKING CHANGE:
The macros are no longer available. They could only be used with compiled code, but if there is any user code that used them, they will have to be replaced with the corresponding functions.
Previously, when a sheet was resized, there were a number of problems:
- Sheets in Cocoa resize their width symmetrically, such that they always remain centered. This was not happening in Cappuccino.
- When a sheet is resized wider than its parent window, the shadow at the top of the sheet was growing wider than the bounds of the parent window's title bar, which makes no sense since the shadow is supposed to be cast by the title bar.
- Sheets had no top border, so when they were resized wider than the parent window, the top edge looked like it was cut off. In Cocoa, sheets have a top border that sits under the title bar of the parent window, and which is visible when the sheet is resized wider than the parent window.
This commit addresses these problems as follows:
- Sheet width is now resized symmetrically.
- Sheet resizing is pinned to the screen bounds.
- The top sheet shadow is pinned to the width of the parent window's content view.
- Sheets now have a top border.
In addition to these changes, a redundant sheet top shadow was eliminated from one of the _CPWindowView subclasses.
Fixes#1846
Previously sheet animation was performed by sizing the sheet from zero to full height when animating in, and then back to zero height when animating out. This caused problems with the resize algorithms, which are not designed to deal with sizing from zero.
Analyzing Cocoa behavior revealed that sheets slide in and out with no resizing.
With this commit, a general purpose mechanism for clipping a window to a rect was added to CPDOMWindowLayer. Clipping was put in CPDOMWindowLayer because that is the class that deals with windows at the global level. CPWindow uses the clipping mechanism to slide the sheet in and out, thus avoiding all resizing problems.
Fixes#1840
Without this fix all regular key events such as `CPKeyDown` would have an undefined location.
Since the location can't be retrieved from the browser on key events, this fix now makes it so that the last seen mouse position is included with each key event.
- Added CPWindow -_parentWindowDidOrderInChild to notify a window when it is directly ordered in by a parent.
- Fixed observing of target view frame changes to work in all possible cases.
- Fixed typo in code introduced in last commit in CPApplication -sendEvent.
- Popovers are implemented as child windows.
- Renamed _CPAttachedWindow/_CPAttachedWindowView to _CPPopoverWindow/_CPPopoverWindowView, since that is its only use.
- The default for CPView -acceptsFirstMouse is now NO, per Cocoa. Subclasses override this as necessary.
- _CPWindowView -hitTest returns self it the mouse is within a resize region, which may be outside the window's frame.
- Fixed an off by one bug in CPDomWindowLayer -insertWindow:atIndex:, where inserting a visible window behind a window it is already behind would cause it to move up one from its intended position.
- Updated the ChildWindows and CPPopover test apps.
