I have created a basic MATLAB UI (without using GUIDE). I basically have a bunch of panels for various things, (sliders, axes, text boxes, etc).
The one thing I would like to do though, it make it so that they scale properly, when I resize the figure. Right now, I painstakingly have to make a re-scale function for every button, panel, sub-panel, etc etc to make it rescale correctly.
Is there an easy way to simply automate the re-scaling here?
Thanks.
Use the GUI Layout Toolbox from the MATLAB File Exchange. I haven't personally used dynamic resizing functionality, but that's one benefit of using this package.
It functions much like using uicontrols, except you can't use the inspect tool on these objects.
EDIT: If you're looking only to do resizing when the figure itself is resized, set the Units property for all your uicontrols to normalized.
You could also use the builtin, but undocumented uigridcontainer and uiflowcontainer.
They have the benefit of e.g. allowing to set contraints, such that e.g. your pushbuttons don't get increased in size, when the full figure does. Check the link for some examples:

So I want to make a custom component. One of the functions I want to have is the ability to create and modify set of points that make up a circle. For example, specify point count:10, and on field update, a circle made up of 10 triangles is drawn in the editor.
Then I want to be able to drag the vertices of the created circle. I feel like I might be able to do this during runtime, but I'm curious how to do it out of runtime. For example, the built in "Box Collider" component has a button that allows you to edit the collider size in the editor.
I looked around and can't find a resource - I feel like there has to be a place for this.
Thanks.
You can execute scripts like if you were in runtime using the [ExecuteInEditMode] annotation at the begining of your class.
Check out the documentation here
For the functionality you want, you have Handles, to manipulate objects properties.
Also you'll want to develop visual aids for your tool, so you can accomplish this using Gizmos.
Google "Custom Editors for Unity" - there's a whole section of the docs for this. You have a wide array of options, from the simple to the powerful.
I recommend catlikecoding's tutorials, that are clearly than the official docs, and take you through the process step by step.
One of them almost exactly describes your situation:

I'm trying to implement a resizable MATLAB UI. But I'm encountering a lot of problems.
In fact, the use of the normalized command is compulsory in order to have a window that automatically resize its content. However the 'normalization' of the uicontrol items it is not always the same. For instance the popupmenu is different from the text and edit. Moreover the FontSize has another behavior with respect to the previous ones.
Is there a simple tutorial out there in which all this stuff is explained?
I didn't find any.
If you're doing this, I would seriously recommend using Ben Tordoff's GUI Layout Toolbox, available from the MATLAB Central File Exchange. It gives you GUI resizing almost for free, and much else besides, such as movable panels and well-implemented tab controls. It comes with good documentation, including some simple tutorials and a decent worked-through example.
Ben is from MathWorks consulting group, and the toolbox is used widely by MathWorks when delivering consulting projects. Although it's not a 'supported' MathWorks product, it's very reliable, and it's freely available for you to include in your own projects.
Without this, it's a huge pain to implement resizing on a GUI of any complexity - to do it properly you can't just rely on the 'normalized' property, you need to implement the ResizeFcn callback on everything, and pretty much re-lay everything out each time there's a resize.
I would like to be able to add a figure container to a matlab gui...
In core matlab, with a docked window style you can have a large number of plots stacked one behind the other, all within a figure container with a tabbed list along the side of the container that you can simply click to bring a particular figure to the front.
Is there a way to have this sort of figure container in a matlab gui?
Use Ben Tordoff's GUI Layout Toolbox. It contains functionality for tabbed panels and dockable/undockable panels that can contain figures, and many other capabilities that you'll find very useful if you are creating GUIs in MATLAB.
You will need to organize your GUI code slightly differently, but it's not hard to learn and there are great examples in the documentation.
It's not really possible to do what you're describing with just regular MATLAB: figures will just dock into the main MATLAB desktop, not into your GUI specifically. The best way (without GUI Layout Toolbox) would probably be to fake a row of tabs using buttons next to each other, with callbacks on the buttons that deleted/hid one plot and drew/revealed another. There is a function uitab that does tabs, but before R2014b it's undocumented, and it's a bit of a pain anyway. Better all round to use GUI Layout Toolbox.
If you're open to play around with undocumented features, this can be done using the java objects behind the matlab figures, e.g. using a little tool from the fileexchange.
This will create a new dock group, just like MATLAB's container for figures, editor etc.
I am trying to understand how compositors work on X (well basically because neither xcompmgr nor cairo-compmgr can draw shadow properly for my awesome wm~~~)
I have read part of the source code both xcompmgr and cairo-compmgr but I still don't really understand how they do that.
I want to know how they know where the shadow should be (well, arround the window for sure, but the shadow might be under other window and don't need to be drawn.), as well as where (on which layer/window) do they draw the shadow. Probably also how all those X extension are used (and what's for) and how cairo-compmgr use cairo to deal with low level X stuff.
It's a little hard for me to learn these from the source code because a lot of stuff (especially X extensions) is poor documented. It will also be helpful just to point out where I should look at.
The simpler you code it, the best it will work.
Get a list of the visible windows
Sort them by inverse z-order (from the bottom-most to the top-most)
Draw the shadow and then the window itself for each window
You need no black magic.
If you are wondering how it works, it's straightforward: you have to use the 'composite' X extension. It enables the overlay window, which is the only visible window on the screen once it is enabled, then you have to draw all the windows on it as you will be provided with a Pixmap for each window.
EDIT:
If you are seeking for documentation, you can use the linux manual (the man command), and the header files, they're the main (also best and perhaps the only real) source of documentation, as all the other sources/websites rely on them afaik.
How can I integrate a Scrollwheel into my application?
I'm currently using Sliders but have found them to be sometimes difficult to control exactly (for example with a linear scale from 0% to 100%). I guess they weren't designed for that purpose and are meant to be used for cases where not pitch perfect control is ok (Volume Control and the likes). However, I really need an exact way of inputting data (other than TextFields, they won't work in my case).
I figured that a Scrollwheel kind of UI Element would be perfect for me. Are there any opensourced Scrollwheels available that would fit my needs?
Horizontal, just like Sliders
Variable Start and End Values
Variable Scale
Small in height
Pretty :)
I tried using the Picker but that didn't work for me since it shows it's values inside of it, which makes it both big and not pretty to look at when used multiple times inside of one View.
If there's nothing available that fulfills my needs (described above) could someone please give me a hint on how to start effectively with creating such a UI element? Thanks!
I've finally found something which fits my needs :)
OBSlider, a subclass of UISlider which allows variable scrubbing speeds – it imitates the behavior seen while scrubbing in iPod.app.
Fulfills all my needs:
Horizontal
Variable Start and End Values
Variable Scale
Small in height
Pretty :)
