< KDE Visual Design Group | HIGRevision as of 02:38, 31 October 2009 by 18.104.22.168 (talk) (Mention QFormLayout)(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff) One of the new changes in KDE 4.x since KDE 3.x is the alignment of form and widget labels. In KDE 3.x, labels were aligned to the left and widgets were aligned to the left. In KDE 4, form labels are now aligned to the right and widgets are aligned to the left, making a group of form widgets appear to be center aligned. In Qt4, using a QFormLayout handles this correctly for you.

In KDE4, a group of widgets is left aligned. This aligns the labels closer to the left edge and makes use of space more efficiently. File:Wiki-alignment-2.png Example of OSX form alignment File:Wiki-alignment-3.png Example of KDE4 form alignment The alignment of groups of widgets is independent, and so you may have different sized groups with different "centered" lines. A group of widgets consists of widgets within some type of natural separation such as a group box or separator bar. File:Wiki-alignment-4.png Example of multiple group alignment in KDE4 Checkboxes Problems with QT 4 The checkbox widget in QT 4 is the input click box on the left and the label on the right. Unfortunately, it difficult to create a checkbox with a label on the right of the input click box. This is a problem because there are common cases when the label on the left of the input click box is better usability. Until there is a resolution that makes configuring the checkbox label to the left of the input click box easier, use the default checkbox alignment (right aligned label), or if possible, put a right-aligned label next to the checkbox, and set the label of the checkbox to "Enabled", "On", or similar. File:Wiki-alignment-5.png Example of aligning checkboxes until there Qt offers an option to align the checkbox label to the left. Aligning Sub-Options When options are subordinate to a checkbox or radiobutton (e.g. Audio level can only be set if the Activate Audio option is selected), this relation should be visualized by indenting the sub-options. There are two options to do so: When you are using a left-aligned checkbox or radio button, indent the sub-options by using a horizontal spacer of SizeType "Minimum". File:Wiki-alignment-7.png Example of aligning sub-options with a horizontal spacer of SizeType "Minimum". When you are using a checkbox that is placed right to its label, indent the sub-options in the same vertical axis as the checkbox.

Please request guidance in #kde-usability if you have any questions regardling Form Label Alignment Grouping related options within a GroupBox In some cases it may be useful to visually separate groups of related options within one GroupBox to facilitate scanning of the dialog. In that case, put a vertical fixed size spacer of 16px height between the options. File:Wiki-alignment-6.png Example of separating groups of related options with a vertical spacer.
