Recently, I saw an article about qt's window for scaling and sliding, but its code is incomplete. Then I wrote the complete code and made it open-source. A slider in the center of the window can dynamically change the size of the subwindow, and hidden buttons can be used to quickly scale the subwindow. It is as follows:Ii. Details 1. Code

ObjectiveMany of today's best software uses "multi-vision" technology.The so-called "multi-vision" refers to the same frame window to display multiple views simultaneously.By using this technique, we can provide the user with more information in the limited control of the frame, and make the user interface more friendly, and enhance the operability of the software.Split typeMFC supports two types of splitter windows: static and dynamic. static

page splitter on the same page must have different IDs, and this ID is set through the options here.
So what is this Pager ID? While solving our project problems, I also took a closer look at some of the core code of drupal and got a deeper understanding of Pager ID.
In Drupal, any page splitter we see is generated based on four global array variables. they are:
Global $ pager_page_array; // store the curr
, we still return to the Code section and follow the function execution path to go back one by one. Finally, we found that the total number of records was changed after being rendered in a block, this block is exactly a pagination view generated by the Views module.
I suddenly realized that it must be the Pager ID of Views! I have encountered this problem before, and I have also reminded myself to pay attention to it in the future. I did not expect it to be neglected this time.

In Ext JS, of course, this function is not less, and in the border layout, is implemented by the functional component Ext.resizer.BorderSplitter, whose parent class is Ext.resizer.Splitter, and Ext.resizer.Splitter is derived from ext.component. The function of Ext.resizer.BorderSplitter is to render a
data, common situations are the live source filter of the WDM model acquisition card. The so-called Pull Mode means that the source filter does not have the ability to send its own data. In this case, generally, the source filter is followed by a parser filter or splitter filter. This filter generally has an independent sub-thread on the input pin, which is responsible for continuously obtaining data from the source filter, after processing, the data
DirectShow uses a modular architecture, where each stage of processing is done by a COM object called a filter. directShow provides a set of standard filters for applications to use, and developers can write their own custom filters that extend the functionality of DirectShow. to define strate, here are the steps needed to play an AVI video file, along with the filters that perform each step:
