How can I get a NSTextField (or any object) to respect the autoresizing options below via code? I want to add new objects to the view dynamically, but when I increase the height of the view, they are anchored to the bottom left, as opposed to the top left as shown, and so new textfields are dropped on top of the old ones.
Is this even possible via code?
Anything you can do in Interface Builder you can do through code.
[myTextField setAutoresizingMask:(NSViewMaxXMargin | NSViewMinYMargin)];
This means that the margin between the right edge of the textView and its superview will be flexible, as will the margin between the bottom edge and its superview. Everything else is static.

What is the correct formula for the location of an NSRulerMarker on a vertical NSRulerView, if the client view is flipped?
The situation: I have a view (let's call it the "main view") that is embedded in an NSScrollView with rulers, and it has subviews. The user can drag these subviews around, and while dragging, I want to indicate the current position on the rulers.
The main view is flipped: The zero point is top-left.
The horizontal position is pretty simple:
NSPoint scroll = myScrollView.documentVisibleRect.origin;
NSRect rect = mySubView.frame;
rulerMarkerDragLeft.markerLocation = rect.origin.x - scroll.x;
However the same method for the vertical position...
rulerMarkerDragTop.markerLocation = rect.origin.y - scroll.y;
does not work. The marker is only in the correct position when the scrollview has been scrolled down to the extreme bottom. For every n points scrolled back up, the marker location is n points too high. This is independent of the main view's size or the size of the visible area.
I can't seem to wrap my head around this problem; I guess there is a value I need to subtract from my result that expresses how far up the scrollview has been scrolled (or rather, how much further it can be scrolled down), but I don't think I can derive that value from myScrollView.documentVisibleRect...?
I may have overlooked something simple, but I can't find the solution.
Edit 2022-11-02 17:17 CET: Found the problem. I had set the NSRulerViews clientView to the contentView of the window. I am now setting it to the "main view" (ie. the view inside the scroll view), and now it works "automagically": I just set the marker locations to the subviews frame, no correction for scroll position or anything else needed.
The solution was simple: the ruler views' clientView needs to be set to the view that is inside the scroll view, not the main content view of the window.
The positioning of the ruler markers is now very straightforward: you just use the local coordinates inside the view, ie. the subviews' frame values.
No correction for scroll position, view height or such necessary.
My mistake was assigning the window's main content view as the rulers' clientView.
I am attempting to implement something similar to Safari where the window's style mask is set to NSFullSizeContentViewWindowMask so the NSToolBar and title bar blur the background view.
This works fine, however I have a view that I need to not be clipped by the toolbar/titlebar, similar to how Safari's WebView has an initial top padding that doesn't cover the content when the view is unschooled.
My attempted solution was to create a dummy NSView which the unclipped views align their top value to, then changing the height constant of the dummy view to the height of the titlebar/toolbar. The issue, however, is that there seems to be no way to calculate the height of the toolbar.
This suggests that I calculate the height by subtracting the height of the contentView from the height of the window, but that only works (returns 0 otherwise as the two heights are equal) if I don't use NSFullSizeContentViewWindowMask which I want to use for the blurring effect.
Am I overlooking something simple, or is there no simple way to accomplish this?
Check NSWindow's contentLayoutRect property.
I have a view-based NSTableView which is embedded in an NSScrollView. It has custom cells that are x number of pixels high. The NSScrollView is the same size as the panel that it is a subview of. I want to resize the entire NSTableView depending on how many rows are in the table.
Everything is working except the resizing. Resizing the scroll view manually in IB seems to have the desired affect, but NSSrollView does not seem to have a class method to resize its view (like NSView has setFrame). Should I be resizing the scollview, the tableview, both, or something else? Does NSScrollView have a setFrame method or similar that I am missing?
Thanks.
Before you try to do it programmatically, make sure you have the outline view's autosizing masks set up properly in the nib file. It sounds like you simply want the outline view (and its scroll view) to always remain the same size as the window that it's inside.
By default, the autosizing masks of an NSScrollView/NSOutlineView combo that you place into a window looks like the following:
In other words, it's set up to always remain the same size as it is now, no matter how large you resize the window to be.
What you want to do is to change the autosizing masks to look like in the image below:
To do that, you click in the white autosizing box wherever there's a dotted red line to toggle it into a solid red line. Once it's configured that way, the scroll view (and table view) will always (automatically) be resized to be the same size as the window that it's in.
There may also be a way to achieve this using Lion's new "auto layout" feature, but I'll have to leave that to someone who has more experience with it.
In case you really need to do this (such as when you want all rows to fit in the scrollview alleviating the need to scroll) and the scroll view is only a portion of the window/view you can do:
[[myTableView enclosingScrollView] setFrame:newFrameRect];
scrollview.frame = CGRrectMake(x, y, w, h);
I am having a problem with my toolbar when i change the orientation of my iPad.
i set my nib file into landscape and everything is all right but when i turned it to portrait my toolbar still has the width from the landscape orientation.
how will i make my toolbar adaptive to the orientation change to portrait?
Landscape:
Portrait:
thanks!
Try adding UIViewAutoresizingFlexibleWidth to the toolbar autoresizingMask like so:
myToolbar.autoresizingMask |= UIViewAutoresizingFlexibleWidth
Or, if your doing this in the Interface Builder, make sure this horizontal bar is selected (others may be selected as well, which is fine):
More from the UIView Class Reference about autoresizingMask:
When a view’s bounds change, that view automatically resizes its
subviews according to each subview’s autoresizing mask. You specify
the value of this mask by combining the constants described in
UIViewAutoresizing using the C bitwise OR operator. Combining these
constants lets you specify which dimensions of the view should grow or
shrink relative to the superview. The default value of this property
is UIViewAutoresizingNone, which indicates that the view should not be
resized at all.
When more than one option along the same axis is set, the default
behavior is to distribute the size difference proportionally among the
flexible portions. The larger the flexible portion, relative to the
other flexible portions, the more it is likely to grow. For example,
suppose this property includes the UIViewAutoresizingFlexibleWidth and
UIViewAutoresizingFlexibleRightMargin constants but does not include
the UIViewAutoresizingFlexibleLeftMargin constant, thus indicating
that the width of the view’s left margin is fixed but that the view’s
width and right margin may change. Thus, the view appears anchored to
the left side of its superview while both the view width and the gap
to the right of the view increase.
If the autoresizing behaviors do not offer the precise layout that you
need for your views, you can use a custom container view and override
its layoutSubviews method to position your subviews more precisely.
In addition to adjusting the flexible width of your toolbar you could create 2 arrays of toolbar items. One for portrait and one for landscape. Fortunately you only have to create the toolbar items once and just add them to the appropriate array(s).
Then during the orientation change you can set the toolbar's items array to the appropriate one.
Good Luck
I have a UIScrollView- scv and a UIView - ocv that have been generated dynamically (no IB), I have added ocv as a subView of scv. Initially i set the content size of scv to the frame size of ocv. But at run time I have to increase the width of ocv because I keep adding subviews onto ocv that extend beyond the left boundary of ocv. Now when I set a new contentSize for my scrollView, It scrolls to show the right side of ocv while the content I want to see is on the left.
Same is the case with top. I keep adding subviews beyond the top boundry of ocv, but i cant scroll to see the top part, i can only scroll to see the bottom empty part..please suggest me a solution..
I believe it is simple. Can u please check if u have selected sc are being checked in your
Interface builder? If everything is fine there, then please increase the height of your scroll view namely scv and also specify your UIView and the additions of subviews to it through code rather than from Interface builder?
