Creating tabs & sections

In some cases, the parametrization becomes quite big which requires a more structured layout. This can be achieved by making use of a Tab and Section, which represent a tab and collapsible section in the interface respectively.

A 2-layered structure using Tab objects looks like this:

import viktor as vkt


class Parametrization(vkt.Parametrization):
    tab_1 = vkt.Tab('Tab 1')
    tab_1.input_1 = vkt.TextField('This is a text field')
    tab_1.input_2 = vkt.NumberField('This is a number field')

    tab_2 = vkt.Tab('Tab 2')
    tab_2.input_1 = vkt.TextField('Text field in Tab 2')
    tab_2.input_2 = vkt.NumberField('Number field in Tab 2')

Parametrization with tabs, no sections

Using Section objects results in the following:

import viktor as vkt


class Parametrization(vkt.Parametrization):
    section_1 = vkt.Section('Section 1')
    section_1.input_1 = vkt.TextField('This is a text field')
    section_1.input_2 = vkt.NumberField('This is a number field')

    section_2 = vkt.Section('Section 2')
    section_2.input_1 = vkt.TextField('Text field in Section 2')
    section_2.input_2 = vkt.NumberField('Number field in Section 2')

Parametrization with sections, no tabs

A parametrization with a maximum depth of 3 layers consists of Tab, Section, and Field objects:

import viktor as vkt


class Parametrization(vkt.Parametrization):
    tab_1 = vkt.Tab('Tab 1')
    tab_1.section_1 = vkt.Section('Section 1')
    tab_1.section_1.input_1 = vkt.TextField('This is a text field')
    tab_1.section_1.input_2 = vkt.NumberField('This is a number field')

    tab_1.section_2 = vkt.Section('Section 2')
    ...

    tab_2 = vkt.Tab('Tab 2')
    ...

Parametrization with sections and tabs

Hide a Tab / Section

New in v14.7.0

Hiding a Tab or Section can be done in a similar way as hiding a field, by setting the visible argument:

vkt.Tab("Tab 2", visible=vkt.Lookup("tab_1.param_x"))

or using a callback function:

vkt.Tab("Tab 2", visible=get_visible)
