You can't select the actual "Screen" by clicking on it in the designer. Even if you have no other elements added. If you add any element, you get the typical resize behavior you would expect, but since you cannot select the screen, you cannot resize it or even view the properties.
You are able to select the screen in the "Objects and Timeline" list. Once you do, you get the expected resize handles and can even view the properties using the tab on the right and resize it manually there.

To keep things simple, let's say I have a window containing a single view, which has auto layout constraints binding all 4 sides to the window container view with offset 0. And assume that this view also has a constraint setting its aspect ratio to a constant value. If I resize the window manually, then then window nicely maintains the desired aspect ratio. But if I click the little green zoom widget, then the window fills up the whole screen, regardless of the aspect ratio, with part of the view being above the top of the screen. Is there some way I can make zooming resize the window as big as it can be, without violating auto layout constraints?
I couldn't very well detect this problem in the delegate method windowWillResize:toSize:, because that doesn't tell me which screen it's thinking about putting the window on. I could try to fix the window size in the windowDidResize: delegate method, at which time I do know what screen it's on, but I'm not sure exactly how to do that without reinventing Auto Layout's wheel.
Apparently someone thinks I wasn't explicit enough, so I'll try again. Steps to reproduce:
In Xcode, create a new macOS App project using XIB interface.
Open MainMenu.xib and select the window.
Reshape the window to be approximately square.
Using the Attribute Inspector, set the Full Screen behavior for the window to Auxiliary Window.
Drag an Image View from the library and drop it in the window.
In the Attributes Inspector, set the image view to show the NSComputer image and scale axes independently.
Expand the image view to fill up the window content area.
With the image view selected, click the button to add new layout constraints.
Add 5 constraints, binding the 4 sides to the container, and setting the aspect ratio. (see screen shot)
Build and Run.
Observe that if you resize the window by dragging an edge or corner, the aspect ratio remains fixed.
Click the green zoom widget in the title bar of the window, and observe that the window expands without regard for the aspect ratio constraint, cutting off part of the image.
I just set up a test project exactly as you specified, and when I invoke the window zoom widget, the window expands and retains its aspect ratio i.e. it works as expected. The only thing I can think of that might be causing your issue: maybe your content hugging and content compression resistance priorities are at odds with your constraints? Mind you, I just left them at the default values and it worked fine. Unfortunately Mac/AppKit development (esp. when using IB) is rife with these kind of odd bugs and weird behaviour, probably because Apple has not given it any love in years, so bugs creep in/fester and they are clearly so DONE with developing UI the 'old fashioned way'. (Using SwiftUI to make a Mac app is just as frustrating, in different ways, so I'll stick with what I know). FYI, I used Xcode 13.4.1 to create this test project. Good luck!
Desired look
I wish to make a toolbar for my app that will contain some simple buttons, each with a single monochromatic icon. Here is an example of some toolbar buttons similar to I'm trying to achieve, from Mail's compose window:
Notice these buttons have a consistent size, inner padding, padding, and shading. This is a pretty consistent style across macOS, present in Mail, Safari, Finder, etc. This leads me to suspect there's a standardized UI component for creating such buttons.
If I use a segmented control, each button looks correct, with each icon being correctly padded:
Now I would like to add individual buttons that match the style.
Attempt 1
My first attempt was to add a "Push Button" (NSButton) to the toolbar:
This resulted in a wide button that's a bit too short, and not lined up with the segmented control:
Attempt 2
My second attempt was to use a segmented control, with only 1 segment.
This resulted in a button that's the right shape, size, etc., but it was off center relative to its label.
Naturally, I can manually adjust the button to match the goal, but I feel like I'm missing something. What's the proper way to create these standard buttons?
This is actually quite easy to do and you were close already.
You can use NSButton for that. Note that it has different styles (defined in NSButton.BezelStyle) to choose from. The default one is the one to use inside windows and modals. But for toolbars, to match the style of segmented controls and search bars, you can choose the style .texturedRounded.
You can also set the style via Interface Builder. Note that you have to select the button itself, not the toolbar item around it.
To get the correct size, you seem to set the icon within the toolbar item, not the button itself.
Here is my result:
So I downloaded CircleView and tried to change the code. The program came with a button, color wheel, 2 sliders, and a view. When ever I add anything (Slider, button, textfield), on run time the things I added wouldn't show up. What am I not doing?
It's a .nib file.
This is the edit page.
This is what I see when running the program.
As you can see, the button and textfield doesn't appear during run time.
By default, when you add a button, the autoresizing mask (aka "springs and struts") are set to the following:
That means that when you resize the window, the button you added will stay in the same spot it originally was, instead of being "pulled" down with the edge of the window. This could potentially cause the buttons or textfields you added to be hidden behind the circle view once you resize the window large enough.
To prevent that from happening you'll want to change the autoresizing mask of the items to be "pinned" to the bottom edge of the window, so that they look like in the following image:
To do that, click on the red I bar at the top of the square to remove it, and then click on the lower I area to turn it on.
Note that you can also select multiple buttons or textfields at one time to change them all at the same time.
I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
Yeah, I did my homework and I found the setFrame:frame display:YES animate:YES but I don't understand how am I find out the height necessary to make it bigger or smaller. Let me exemplify: I'm making kind of spotlight search tool but when the user start the app it will just have a textfield (to type in the search keywords) and a button (Filter Settings) and the window fits the size of these two objects (NOTE: The window start position is on the center and on the top of the screen). When the user hits the "Filter Settings" button I want the window to make an animation going down and then showing the "check box group" that filters the search results.
In your case you need to find out the height of the check box group that you are adding to the view. An easy way to do this is to make a seperate view in your nib that contains the check boxes. Hook up the view to the window using IB, and when it is time to display the check boxes add that view to the windows content view and animate the window resize.
