Set the width of a scrollbar in wxWidgets on Windows - windows

I'm looking for a way to set the width of the scrollbar in may class which inherits from wxScrolledWindow. I wouldn't mind editing the framework source code (3.1.0). I've looked there but I could not find the solution for my problem since the wxScrolledWindow and its base classes don't seem to use the wxScrollBar class.

You can't change the width (or any other aspect of the appearance) of the standard scroll bars, used for scrolling a window -- this is part of the native look-and-feel you get when using wxWidgets.
If you absolutely need to do something different (why?), you have no choice but to write your own scrolled window class using a plain window without scrollbars and one or two standalone wxScrollBars for scrolling it. Needless to say, this is going to be complicated and won't work as well as native scrolling, so you shouldn't do it unless you really can't live without this.

Xcode Storyboard Zoom Magnification

I'm currently using the storyboard feature to position views. Due to the nature of these views, they need to be positioned with precision.
I'd like to view the Storyboard Scene/View in a magnification/zoom level greater than 100%, but it doesn't seem to be possible using the standard zoom in/out feature.
Is it possible to do this?
Note - I understand how to use the 'Size Inspector'.
It doesn't look like there is a way to do this, but there is at least one alternative that works fairly well:
Go to System Preferences > Accessibility > Zoom
Turn on the keyboard shortcut or scroll gesture
You should now be able to zoom in on any part of the operating system, including storyboards.
To make editing even easier, enable these options, some of which are found under More Options...:
Turn off Smooth images
Change Zoom Style to Picture-in-picture
Window Position: Follow mouse cursor
Cursor style: Crosshair
Enable temporary zoom
No, I am almost positive it is not possible to do this. You are stuck with 100% zoom. However, if you need great precision, you could try selecting the element you wish to move and use the arrow-keys to move the item around accurately.
However, like MacN00b, I do not use Storyboards a lot, so perhaps there is some top-super-secret setting buried somewhere.
This is one of the reasons I don't use storyboard but prefer good old fashion individual xibs. I don't think it is possible to zoom in past 100%, you may try double clicking on the background, I know that normally zooms in.

NSScrollView and lion .. is it possible to only show scrollbars when scrolling

Is it possible to have an NSScrollView ignore the system preferences setting and only show scrollers when scrolling. My application is designed for the overlay style scrollers only unfortunately, so I want to avoid having to adjust the containing content views.
Is this possible?
I would take a look at NSScroller's setScrollerStyle:. That should do the job.
However, I'd like to share that I personally think forcing users into using one style of scrollers over the other is indicative of bad design. The system allows users to choose and I believe apps should honor that choice. The fact that your content view doesn't handle horizontal nor vertical resizing is a big red flag and I would revisit that design choice.
Good luck.

Can I change NSScreen visibleframe?

I trying to create a toolbar that docks on the top of the screen below the OS X menu bar.
I would like no other application's to be able to overlap my application when they are maximized. I can get the visible frame dimensions using NSScreen's visibleframe method, but can I adjust the visibleframe to omit the size and position of my application?
The simple answer is that no, you can't. I think that the only way to change the screen's visibleRect would be to inject code into AppKit and swizzle the method.
Even then, it might not do what you want because that method might not be what Apple uses to determine the "safe area" for windows and almost certainly would not work with Carbon apps.
Nothing you do with window levels will change this.
What you could do is use the Accessibility framework to reposition windows if you detect that their frames have changed such that they overlap your toolbar window. Unfortunately, I think you might need use polling for this.
Try setting your window's level to NSDockWindowLevel.
This may not work, depending on whether the system subtracts all windows on that level or only ever the Dock's window, but it's worth a try.

How to add left/bottom/right panes to Mac application as in XCode?

XCode 4 (but also iTunes and other Mac apps) provide side or bottom bars that can be shown or hidden with a smooth animation as the user presses a button.
How can I obtain a similar effect in my applications?
You can use NSSplitView to do that. You can have more than 2 subviews in a split view (left|center|right) and you can build a kind of hierarchy for the different bars (center consists of top and lower split views).
The show/hide effect is not built in, though. But you should be able to use the animator to do that. Most certainly you can also define animations for hiding a view.
You could also use the BWSplitView of http://brandonwalkin.com/bwtoolkit/ where the show/hide animation is already included.
You could also consider subclassing NSViewAnimation, which I believe Xcode uses in a number of places to achieve its fancy animation effects.

Getting rid of the focus rect on an NSCell. Only shows up when right clicking

I have an NSCell subclass that I do all kinds of custom drawing in. The only time things seem to be entirely out of my control is when right clicking a cell to show the associated context menu. While showing it's context menu, the table (or cell - not sure which exactly is doing this) draws a focus rect. I would like to get rid of this, or at least find a way to draw my own version of it that better fits within my interface.
I have tried about 15 different methods that seem like they could give me control over this focus rect drawing itself (various first responder methods, various drawing methods, various highlight color methods, etc.), but I have yet to find something that changes anything about it.
Screenshot of the problem: http://twitpic.com/3zx2t
I am almost annoyed enough to class-dump AppKit and try to find whatever private method it's using to draw this annoying focus rect. Nothing else I do has any effect on it. Any help here would really save both my sanity and lots of future hair pulling.
Thanks so much!
Without completely overriding your table view's -drawRect: this is the only other way I know to get rid of the context menu highlight rect.
- (void)_drawContextMenuHighlightForIndexes:(NSIndexSet *)rowIndexes clipRect:(NSRect)rect {
return;
}
This is the method, used in Leopard at least, to draw the highlight around cells that will be activated upon by a context menu. It is unfortunately called directly by NSTableView's -drawRect: method and as far as I know there is no other way to signal your disinterest in having those highlights drawn.
Of course this is private API, it may stop working in Snow Leopard, or some other release. But at worst that means that somewhere along the way the context menu highlight may start up again in your programs on newer releases or some other functionality using this method may not work later. You have been warned.
On 10.5 and later, NSTableView allows you to bring up a contextual menu on any item in the table (that is, without having the side effect of changing the selection.)
It draws that 'focus rect' to indicate which item(s) are being acted on by the contextual menu.
