| + | ===== ListView ===== | ||
| + | * To start creating lists in QtQuick, you must organize your files first. | ||
| + | * You need, at least, three files | ||
| + | * Single item view | ||
| + | * All the visual elements from each list item and how they appear are in this file | ||
| + | * ListModel | ||
| + | * This is the file presented before, an array of ListElements containing all information from each item | ||
| + | * Main file | ||
| + | * This file will contain the ListView call, the ListModel and the Component for each single item view that will be repeated | ||
| - | ===== Model views ===== | + | * The first thing to do is to create the list item layout file ... |
| + | * See example: addon/ | ||
| + | <code javascript> | ||
| + | ... | ||
| + | Text { | ||
| + | id: nameTxt | ||
| + | font.family: | ||
| + | color: "# | ||
| + | font.pixelSize: | ||
| + | text: "< | ||
| + | anchors.left: | ||
| + | anchors.top: | ||
| + | anchors.topMargin: | ||
| + | } | ||
| + | ...</ | ||
| - | ==== ListView ==== | + | * ... then you need to make the item flexible enough to accept the variables you need |
| + | * See example: addon/ | ||
| + | <code javascript> | ||
| + | ... | ||
| + | property string intern_name | ||
| + | property string intern_surname | ||
| + | property string intern_telephone | ||
| + | ... | ||
| + | } | ||
| + | Text { | ||
| + | id: nameTxt | ||
| + | font.family: | ||
| + | color: "# | ||
| + | font.pixelSize: | ||
| + | text: "< | ||
| + | anchors.left: | ||
| + | anchors.top: | ||
| + | anchors.topMargin: | ||
| + | } | ||
| + | ...</ | ||
| - | ==== GridView ==== | + | * Once you’ve done all of this, now you just need to set the ListView inside the main file |
| + | * See example: addon/ | ||
| + | <code javascript> | ||
| + | ListView { | ||
| + | id: listExample | ||
| + | orientation: | ||
| + | model: ListModelExample {} | ||
| + | delegate: itemComponent | ||
| + | } | ||
| + | Component { | ||
| + | id: itemComponent | ||
| + | ListItemExample { | ||
| + | intern_name: | ||
| + | intern_surname: | ||
| + | intern_telephone: | ||
| + | intern_icon: | ||
| + | } | ||
| + | } | ||
| + | ...</ | ||
