I am new to cinema 4d and I built a model which is easily viewable in my right, top, and front viewports, but in perspective view I can't see anything, and I can't figure out how to reset or recenter the view. Anybody know how to do this?
This might be useful too:
You can press "o" to center the selected Object in the current viewport
Besides the undo command, there is also "Frame Default" command in the edit menu of the view panel.
Well, I didn't quite figure out a "reset" button, but what I did realize is that cinema4d has two styles of undo - one for actions undertaken within the program, and one for the views themselves, so I was able to successfully undo using the viewpane undo mode.

I have a Image View on my storyboard, and when I am trying to use it as a background. No matter what I do, it always stays on top. How would I change it so that it would be a background image, I don't care weather I do it programmatically through swift or through another way.
In the Xcode Interface Builder, you can adjust which views are in the front by selecting the view and going to Editor -> Arrange -> Send to Front, Back, etc.
This can also be done programmatically using UIView methods like bringSubviewToFront:
By moving any of item up/down you can set their layer state. The first one will be on back then second will appear on the first one then.... last one will appear on top most.
I hope this will help you.
If you decide to do it programmatically, you can modify the zPosition property of the view:
myImageView.layer.zPosition = 1
Higher numbers are closer to your face, lower numbers are closer to the screen. So to set your image view as a background, make sure the other views have higher z-positions than it.
I am just learning Xcode. I did something that caused a view controller to turn black below the navigation bar when you build app.
It looks white in storyboard.
Also, when I pull a label onto the storyboard, it aligns to the left margin and does not show the drag boxes around it.
I may have inadvertently clicked something but when I compared it in attributes and identity inspectors line by line to another project, nothing seems amiss, i.e. everything is the default value.
Has anyone run across this?
There is not code in associated class that would cause this as it is generic i.e. plain vanilla.
Would appreciate any suggestions. Thx.
With that little information i'd say you removed the root view of the controller?
Either way, you say there is no code, so I'd suggest you simply delete that controller and create another one (bottom right, objects, viewcontroller). Since it's empty you're not gonna lose any data or time :)
Then link it to your class in the Identity Inspector and you're good to go as if it was a new one.
I need to implement the functionality that this library provides: XYOrigami. The main issue, is I must implement it to fold on the center view when the left view is revealed rather fold the side views. Unfortunately, this has become quite a task (and I'm currently looking at manipulating the library below to do so). The left tray should be just a tray with a width of 100 to 200. When it comes out, the center view should have a cringle origami effect and fold until the tray is hidden again. Is anyone aware of a library that does this or a way to accomplish this effect.
I think you will get the sample code in mpospese / EnterTheMatrix
repository.
Just have a look at the second last tab,"The Fold Animation" & then click view.
I think this view can be taken as the center view for your case & XYOrigami as the side menu.
You many need to tweak the EnterTheMatrix to fold-unfold horizontally unlikely as it fold-unfold vertically by default.
I hope you can make a new custom component hybridized from the above two Custom controls.
Happy Coding.
Hope that Helps.
If I subclass QLabel and I add a QLabel directly to my QDialog, it works fine. If I add this label inside a ScrollArea, the thing I’m drawing doesn’t show unless I resize the dialog itself. Yes, weird.
I’ve setup compilable example code that indicates what the problem is. What I am trying to do is to select an area of an image with my mouse, by drawing a rectangle on the corresponding area. The images my program is designed to work with can be very large, and thus, I need to have a scroll area so as the dialog to stay at a logical dimension, and not to fill the entire screen (or even multiple workspaces, if we are talking about a linux machine with multiple desktops).
Everything works fine, except that the drawing (selection-rectangle) isn’t visible unless the dialog is resized – manually. I think I have to update something while drawing, but I’m not sure what. Well, here’s the example code: http://paste.ubuntu.com/1151553/
Another issues that I don’t know how to solve (and I want your suggestions there) are (1) when the user is selecting an area, how to set it to automatically scroll when the user actually selects an area by pushing against to a wall of the scroll area (I guess I am understandable here). (2) is there a way to let the user select a rectangle and then, when he left-clicks on a position with holding down the [Shift] button, the bottom right edge of his previous selection to actually go through the point he clicks at?
The documentation indicates that you have to set a Layout somehow somewhere, but I'm not sure how to do this to my occassion.
Thanks in advance for any help.
about problem (1):
just use of Event. i think mouse Enter Event or Leave Event is good for that.
and to do that i think you can use a hidden rectangular that fill the whole of the screen.
and over write the mouse leave Event for that rectangular and tell in that function , to scroll the page.
Summery:
I have a custom UITabBarAutoRotateController which returns YES from shouldAutorotateToInterfaceOrientation. This has no effect.
If I minimize and show the app again, the rotation issue goes away.
How do I refresh the screen so the user does not have to do this (so rotation works again)?
Details (setup graphically, so no code):
I have two UITabBarController in MainWindow.xib. I only want one to show at a time. So I am linking graphically rootViewController = tabBarController_name1. There is also tabBarController_name2.
I will also have an alert MessageBox for a user to choose what type of application they need, and it will choose a tab bar controller based on their request (per customer definition). This is commented out for now.
There is a bug with Rotation when two UITabBarControllers exist on the same xib. When I try to rotate the screen, it stays upward with wherever the main screen button (power button looking button) faces. HandleOrientationChange does not get called on the active custom ViewController being shown.
The reason I believe it's a bug is because if I hit the main screen button (minimizing the application), and click back on the application (brings it back to the foreground), rotation works perfectly!
Sorry for making you read all that mumbo :). My true question is, "Is there anyway I could refresh the main window or likewise UITabBarController's to get rotation working (without requiring the program be minimized and shown)"? A work-around, if you will?
p.s. I cannot use Storyboard for backwards compatibility reasons. The customer will be receiving this code/project. So I would like to keep this in one graphical page, rather than hiding/showing UITabBarItem's.
EDIT: two-uitabbarcontrollers-and-autorotation and uitabbarcontrollers-and-uinavigationcontrollers were both helpful, but did not address "why" this issue happens. "noob" here when it comes to xcode :)
Tab bar controller inside a navigation controller, or sharing a navigation root view is the answer. Do not use a TabBarViewController. Which, as a noob, I'm not quite sure why TabBarViewController exists (or at least isn't depreciated).
Dragging two TabBarViewControllers into the same page should result in a warning saying that you probably want to implement TabBarViewController by making a custom UIViewController and attaching a plain UITabBar to it.
Frustrating...but finally making progress :)
