Resizing Window and View
Post: #1
I'm trying to get my preferences to work and resize my window and view but it currently only updates the window. Here's the code that's handling it all:
It will resize the window correctly but the view stays the same 600x400 rectangle in the lower left corner. Any ideas?
Code:
- (void)resize
{
NSWindow *mainWindow = [self window];
NSRect newSize = [mainWindow frame];
switch(windowSize)
{
case w600x400 :
{
newSize.size.width = 600;
newSize.size.height = 400;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
case w640x426 :
{
newSize.size.width = 640;
newSize.size.height = 426;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
case w800x533 :
{
newSize.size.width = 800;
newSize.size.height = 533;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
case w1024x682 :
{
newSize.size.width = 1024;
newSize.size.height = 682;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
case w1152x768 :
{
newSize.size.width = 1152;
newSize.size.height = 768;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
case w1280x854 :
{
newSize.size.width = 1280;
newSize.size.height = 854;
[self setFrame:newSize];
[mainWindow setFrame:newSize
display:YES];
break;
}
}
}

You can't use the Auto Save Name field of the window? In Interface Builder, if you put a name in there, the app will automatically save the window size and position to the user's preferences file.
If you can't, I think the problem you're having is that you think the following holds true for positioning your window:
(0, 0) ----->
|
|
|
V
when in reality, windows are positioned using this coordinate system:
^
|
|
|
(0, 0) ----->
So what happens is when you resize your window, the top and right sides come towards the lower right which is (0, 0) of the coordinate system instead of the bottom and left sides coming towards the upper right which is what you're expecting to happen, I think.
So how to fix that? I think what I've done in the past is I hold on to the original dimensions of the window before I resize it, resize the window then get the differences in the dimensions, then adjust the position by those differences. So if your window is 25 pixels smaller, then you have to increase the y position by 25 and so on. Frankly, it's just easier to use the Auto Save Name field if you can.

What if, instead of resizing your view manually, you set the view's resizing mode in Interface Builder? Then it'd keep track for free.

@Malarkey:That's not really what I needed help with. My window resizes fine. That's not the problem. My view, on the other hand, (what is referred to as self in the code), is not resizing to the proper size. It just remains at 600x400 no matter what. That's what I'm trying to fix. But thanks for trying.
@Tomorrow:How do I do that? I remember once doing it, but all current attempts just keep failing.
p.s. I'm not letting the user free resize the window, just in case anyone thought that. There is only a limited number of choices for size.

Doh! Yeah, I totally misread your post. Well, one thing that I've found helpful in figuring out how to do what TomorrowPlusX says is to download and build the Sproing project and play around with it.

Did you create your window and view in IB, or are you doing it programmatically? If the former, it's just a matter of selecting your view, hitting command-3, and clicking the center springs on the inspector.
If it's the latter, you want to look up NSView's - (void)setAutoresizingMask:(unsigned int)mask.
I haven't manually set resizing modes in a while, but you'd just set:
And, yeah, Malarky's link.

Yeah, the nice thing about Sproing is that you can visually see how the different options (aka, the springs) work. Plus, it will tell you what flags you need to set if you're doing it programmatically instead of through IB.
