问题描述
假设您有一个这样的标签面板:
Let's say you have a tab-panel like so :
editor: layout [
below
t: tab-panel 350x350 [
"tab 1" [
below
b: button 75x25 "Interpret" on-click [do a/text ]
a: area 320x250
]
]
]
view editor
如何动态地向其添加新标签,使其具有当前标签的内容?
How could I dynamically add a new tab to it so that has the contents of the current tab?
推荐答案
它们是动态添加新标签的几种方法,但是在所有情况下,归结为添加:
They are several ways to add a new tab dynamically, but in all cases, it boils down to adding:
- 制表符标签,作为
string!
至t/data
块. - 与
t/pane
块相对应的panel
面object!
.
- A tab label as a
string!
tot/data
block. - A corresponding
panel
faceobject!
tot/pane
block.
这是一个完全正常的示例代码:
Here is a fully working example code:
tab1: [
below
button 75x25 "Interpret" on-click [do face/parent/pane/2/text ]
area 320x250
]
editor: layout compose/deep/only [
below
button "add tab" [
append t/data "tab 2"
append t/pane make face! [type: 'panel pane: layout/only tab1]
]
t: tab-panel 350x350 ["tab 1" (tab1)]
]
view editor
一些评论:
-
tab1
定义已被外部化,因此可以将其定义用于其他选项卡内容(根据您的要求). -
a:
单词已被删除,因为它无法重复,现在可以通过在脸部树上行走来访问当前选项卡面板中的当前area
脸部.b:
定义由于相同的原因而被删除(无论如何也未使用).
tab1
definition has been externalized, so its definition can be reused for another tab content (as per your request).a:
word has been removed as it cannot be duplicated, access to the currentarea
face in current tab panel is now done by walking up the face tree.b:
definition has been dropped for same reason (and it's not used anyway).
