Human interface guidelines (HIG) are software development documents that offer
application developers a set of recommendations. Their aim is to improve the
experience for users by making application interfaces more consistent and
hence more intuitive and learnable.
[[/About|Learn more about the philosophy behind the KDE HIG]]
= Structure =
== Conceptual Model ==
* Have a clear [[Projects/Usability/HIG/Vision|vision]] what your application will achieve and what not.
* Meet the needs of KDE's [[Projects/Usability/HIG/Persona|personas]] in your application.
* Define a [[Projects/Usability/HIG/Scenario|scenario]] where persona(s) interact with your application.
* Specify user's goals and [[Projects/Usability/HIG/UsabilityRequirements|requirements]].
== Task Flow ==
* Support tasks from the [[Projects/Usability/HIG/RealWorld|real world]].
* Describe the [[Projects/Usability/HIG/IntendedUse|intended use]].
== Organizational Model ==
<div style="display: none;">
Use cases / , Task aggregation
* [[Terminology]]
* Information architecture, Interface management, Window style, Basic arrangement, Screen design, Design Pattern
* [[Projects/Usability/HIG/CentralConfiguration|central configuration]]
* [[Projects/Usability/HIG/NotificationMechanism|Notification mechanism]]
*Minimize to tray (perhaps at behaviour>navigation)
= Behaviour =
== Viewing and Navigation ==
=== Access functions ===
* Apply a [[Projects/Usability/HIG/Menu_Bar|menu bar]] to every standard application.
* Try to omit the [[Projects/Usability/HIG/StatusBar| status bar]] from your application.
* Provide a [[Projects/Usability/HIG/ContextMenu|context menu]] for controls with implicit functions.
* Provide a [[Projects/Usability/HIG/Toolbar|toolbar]] for frequently used functions.
* Use a [[Projects/Usability/HIG/Buttons|push button]] to initiate an action when the user clicks it.
* Use a [[Projects/Usability/HIG/Toggle_Buttons|toogle button]] to indicate a state, preferably in toolbars only.
* Use a [[Projects/Usability/HIG/Command_Link|command link]] to navigate between pages.
* Support keyboard access by [[Projects/Usability/HIG/Keyboard_Accelerators|accelerators]] and [[Projects/Usability/HIG/Keyboard_Shortcuts|shortcuts]].
* Follow the guidelines for [[Projects/Usability/HIG/Dialogs|dialogs]] for secondary windows.
=== Grouping ===
* Arrange associated controls by using a labeled [[Projects/Usability/HIG/GroupBox| group box]] or an unlabeled [[Projects/Usability/HIG/GroupBox| frame]].
* Allow users to resize aligned groups by placing a [[Projects/Usability/HIG/Splitter| splitter]] between the groups.
* Use [[Projects/Usability/HIG/TabControl|tabs]] to show related information on separate pages.
* Provide an [[Projects/Usability/HIG/Accordion|accordion]] (aka tool box) for different views to content.
=== Complex views ===
* Use a [[Projects/Usability/HIG/ListView| list view]] to show some items out of one category.
* Use a [[Projects/Usability/HIG/TreeView| tree view]] to show items with a single, natural, hierarchical categorization.
* If you really need to create your own widget follow the guidelines for [[Projects/Usability/HIG/CustomControls| custom controls]].

* Use [[Projects/Usability/HIG/Radio Buttons|radio buttons]] for selection of 1 out of a few items.
* Use one or more [[Projects/Usability/HIG/Check_Box|check boxes]] for clear options or to select items out of a small number of options.
* Use a [[Projects/Usability/HIG/DropDown| drop-down]] list for selection of 1 out of a small number of items.
* Use a [[Projects/Usability/HIG/Combo_Box| combo box]] to select 1 out of a small number of items where users should be able to add items.
* Use a [[Projects/Usability/HIG/ListView|list view]] to select 1 singular item out of a potentially big list.
* Apply the [[Projects/Usability/HIG/DualList| dual list pattern]] for several selections out of a large number of (multiple) items.
=== Unconstrained input ===
* Provide a [[Projects/Usability/HIG/LineEdit| line edit]] to enter one line of text.
* Provide a [[Projects/Usability/HIG/TextEdit| text edit]] to enter multiple lines of texts.
* Use a [[Projects/Usability/HIG/TableView| table view]] to arrange data in rows and columns with inline editing feature.
=== Constrained input ===
* Use a [[Projects/Usability/HIG/Spin_Box|spin box]] for numerical input within a range and with fix steps.
* Use a [[Projects/Usability/HIG/Slider|slider]] for arbitrary changes within a defined range.
* Apply the [[Projects/Usability/HIG/Slider_and_Spin_Box|slider and spin box pattern]] for numeric input with both large changes and precise control.
* Use [[Projects/Usability/HIG/Date_Time_Pickers|date and time pickers]] for formatted input of datum, time of day, or periods etc.
== User Assistance ==
=== User-driven information ===
* Provide [[Projects/Usability/HIG/Tooltip|tool-tips]] for user driven information.
=== System triggered notification ===
* Provide a [[Projects/Usability/HIG/MessageWidget| message panel]] to inform users about non-critical problems.
* Use a [[Projects/Usability/HIG/Notifications|notification]] as system-triggered message to inform about events out of the current context.

* Take care about [[Projects/Usability/HIG/localization| localization]] of your project.
* Do not apply [[Projects/Usability/HIG/Capitalization|capitalization]] except for titles and in case of sentence style.
