Advanced GuiWidgets: DropDown - Handling Default HTML Select¶
DropDown object in Arjuna represents the Select-style control in the UI. Here, we cover handling of a default-HTML select control which has <select>` as the root tag and **option as the tag for an option.
Defining and Using a DropDown In Code¶
You can create a DropDown using the dropdown factory call of a GuiApp (assume app to be GuiApp object):
Defining DropDown in GNS and Using it in Code¶
You can also define a DropDown in a GNS File.
In the GNS file for a label corresponding to a GuiMultiElement, add the type entry and set it to dropdown, for example:
role: type: dropdown id: default_role
In your code, you can create an element of this as usual, however this time you’ll get a DropDown object instead of GuiElement.
element = app.gns.role
Interacting with DropDown¶
It provides various properties and methods for a higher level interaction with a drop down list.
You can select an option by its visible text by calling select_text method of DropDown.
DropDown provides various enquiry methods - has_visible_text_selected, has_value_selected, has_index_selected**.
DropDown also has enquirable properties - value and text.
There are other ways of selection as well - select_value to select by value attribute of an option, select_index to select an option present at provided index.
DropDown also has a way of selecting an option by setting its text property. This is similar to .text property setting of a text-box. It is different from select_text method in terms of implementation. select_text uses DOM inquiry to match the text of an option and then clicks it to select it. Setting the .text property similuates the user action where the user types a string in a focused/highlighted select control to select an option (in technical terms it is equivalent of sendkeys).
