I am looking for an SWT widget that would have the look and behavior similar to Swing's JPlitPane. Is there such a widget in SWT, and if not, what's the closest to it?
(A pane split to two with the ability to move the border between the two parts)
Take a look at the SashForm:
From the javadoc...
The SashForm is a composite control that lays out its children in a row or column arrangement (as specified by the orientation) and places a Sash between each child. One child may be maximized to occupy the entire size of the SashForm. The relative sizes of the children may be specified using weights.

Anchor boxes are important to YoloV3, especially when running on the custom dataset.
I knew that anchor boxes are calculated with bboxes height and width, through kmeans.
After I got the anchor boxes, they are supposed to be distributed into 3 scales. By default, the 3 scales are 1313, 2626, 52*52.
So, the question is how to decide which anchor belongs to which scale?
Currently, I'm sorting those anchors based on their summary, since the 13*13 scale should have a larger anchor.
Am I right here?
Following is an example:
Then, I sort them:
.
In the second image, the first 3 anchor boxes belongs to 13*13 scale.
I read lots of blogs and codes, but seems no one have explained that clearly, may because of it's too simple for them.

In file main. See at v1UI_integration branch and init_v1_ui and real_new_tab code. I known, there is big amount of code, so I do not paste it here.
Problem is, when trying to add more than two children to GtkOverlay, one of it always get at index 0 and I cannot reorder it with gtk_overlay_reorder_overlay. I try with different approach by use three overlays (one root and two children) and it worked, but problem was I cannot interact with items, even when setting gtk_overlay_set_overlay_pass_through to children. What i do wrong?
This is my code:
<table>...Some content...</table>
<table>...Another content...</table>
I want to put the second table on top of the first table. This is to be used as an email template (in some clients position and margin are not available).
Those are the only two options available (outside of transform, which definitely won't work if position isn't available) that will allow one element to invade another element's space. If you can't use position or margin, then you're out of luck, and you need to re-evaluate what you are trying to achieve and why. Any chance you could do this with images?
There are always ways...not always elegant, but when you have limited options, 'works' is often all you really need. IMO, creativity is as much about solving a problem with limited options as it is thinking 'outside the box'.
Most email clients allow you to set 'height', so simply wrap the first table (the background) in a div and give that div height:0px;. the table will overflow the div, but the next element won't respect it's space because it has 0 height, and will effectively be layered in front.

If you want the size of the tables to match exactly, you'll probably have to explicitly set heights and widths, but the fiddle above illustrates the basic concept. Hope this helps!
EDIT:
Based on the additional info in the comment (the second table should only partly overlap the first table) here is an updated fiddle: https://jsfiddle.net/acq3ob6y/1/
EDIT #2:
Dang. Outlook switching to the Word/Office rendering engine for HTML/CSS might be the only way possible to get WORSE than the IE version. Sigh. (Thanks to #Gortonington for the comment/clarification, though!)
Ok, then, the idea of a background image is only a problem for retina displays (if you want them to be all crisp and beautiful and retina-ie), and retina devices are going to be handling CSS in a more modern way (hopefully!), so how about this as a solution: Media Query targeting device resolution loads CSS with the double-size img and uses css background-size to constrain it: http://jsfiddle.net/tcyjo7ok
Third try is a charm? At least the list of options is growing...
The only way to overlay two elements across email clients is through use of background images. Even this can be broken in some clients and requires a lot of conditional and reiterate code (backgrounds.cm is good resource for email bg images).
This is the only option that will display in MOST clients. Even this is still very restricted and not very agile to use (but that is true in ALL email coding). Most other techniques will only work for a couple clients and break completely in all others.
I have to implement this grid of divs. It won't change often, but it may at some point (meaning a box may be removed, and another resized). Each black box will eventually contain an image or a word, but that's not important.
How do I pull this off? Is there a more elegant way than by absolutely positioning every single box and manually entering every X/Y/width/height?
A grid based approach would be my recommendation.
Something like: http://960.gs/

How do I overlay widgets in Qt?
I want to create some widgets and place them out-of-layout, but rather tweak their size and position when some other widget's geometry is changed.
Something like the buttons on the screenshot:
You just need to create your QPushButton (or any QWidget), indicate its parent QWidget and then display it.
Don't add it to the parent layout else you will not be able to move it as you want.
Don't forget to indicate its parent else it will be displayed as independant QWidget.
In these conditions your QPushButton will be considered as child of the QWidget but not member of the parent's layout. So it will be a "floating" child and you must manage it's behaviour when resizing parent's QWidget.
If you want a unified behaviour for all overlay buttons, you should subclass QLayout and redefine members bahaviour.
If they're child of a widget without a layout, you should be able to move them around as you please, I think.
I needed a widget like this for a project I'm working on, so I took Patrice advice and wrote this code (Python) PyQt4 Widget Overlay
