wui Designer

Visual designer for wui windows. Projects are saved as WML (.wml) files and can be exported as Go code. Run it with go run ./cmd/designer [project.wml].

Controls (toolbox)

Every WML element type, property and event is supported, plus the TreeView.

Properties

Properties are shown in collapsible groups. Besides the usual ones the designer edits: button kind / note / default, check box three-state and push-like, numbers-only and text alignment of edit controls, ListView view, columns, rows, grid lines, check boxes, sorting, RichEdit word wrap / link detection / background, MonthCalendar week numbers, ImageView image file, mode and back color, ScrollBar vertical / range / page, window min and max size and center on show, TabStop and a tool tip for every control.

Events

The Events group lists every event of the selected control or window (the list comes from the WML schema). Events that have code are marked with *. Edit Code... opens the handler; the template has the exact signature the library expects. Standard packages used in handler code (fmt, time, os, strings, strconv, math, sort, errors, log) are imported automatically in the exported Go code.

File format

The project is a normal WML document. WML never contains code, so:

• handler code is stored in one XML comment (wui-designer:events),
• properties WML cannot express (tool tips, the TreeView nodes) are stored in a second comment (wui-designer:props),
• a TreeView is written as a Panel at the same place, noted in the props comment. An application that loads the file with package wml sees an empty Panel there, the designer brings the TreeView back.

Go export (Ctrl+E) writes everything, including tool tips and tree nodes.

Not in the designer

Splitter, NativeToolBar, ToolBar, layouts (HBox / VBox / Dock / Grid), menus, image lists and tab order have no WML representation and are set in code.
