We sort data through Ext. Data. groupingstore and provide it to gridpanel.
var store = new Ext.data.GroupingStore({ reader:reader, data:data, groupField:‘sex‘, sortInfo:{field:‘id‘,direction:‘asc‘}});
The reader and data here are the original ones. groupfield specifies which one is to be grouped and must be set to sortinfo. This parameter requires two items. field is the sorting attribute, direction is the sorting m

But if we are not using Viewpager, but ScrollView, then we need to handle the sliding conflict manually .Scenario 2: The system does not know which layer the user wants to slide, so there is a problem when the finger slips, or only one layer can slide, or both the inside and outside of the two layers sliding very fast. The actual development is mainly inside and outside two layers simultaneously can slide up and down or both inside and
Data Structure Experiment 2:Linear table experiment
Lab Purpose
[Consolidate the data structure of a linear table and learn how to apply a linear table .]
1. Review the logical structure of a linear table, physical storage structure and common operations of a linear table.
2. Learn to use the knowledge of linear tables to solve practical problems.
3. Further consolidate the program debugging methods.

For example, in project development, we need to specify the user's gender, at this time can be defined as a constant sex, assigned to "male", in the need to specify a user-specific place to call this constan

Handle Classes and inheritanceOne of the ironies of object-oriented programming in C + + is that object-oriented programming cannot be used, instead, pointers or references must be used. For example, in the following code snippet:void Get_prices (Item_base object, const item_base *pointer, const item_base reference) { //which version ofnet_p Called is determined at run time cout Calls made through pointer and reference
