All Types

ao_updateonidle calls onupdate once per application idle cycle, i.e.

avo_activateonloaded activates the activator's clients from the form's onloaded event (needed because oncreate runs before the components are fully operable); avo_activatedelayed instead defers activation until the main event loop starts, after application.run.

bmo_masked enables masking, computed from the alpha channel for a loaded PNG image, or otherwise from the color set in tmaskedbitmap.transparentcolor, combined with bmo_colormask (color-based) or bmo_graymask (luminance-based) masking.

If bdo_autoapply is set, applyupdates is called automatically after post.

cp_center centers both glyph and caption; the other values position the caption at an edge or corner of the widget, named after that edge/corner (e.g.

co_rowdatachange makes the column fire onrowsdatachanged when its value is changed through an editor subwidget embedded in a cell, not only when the row's data is changed programmatically.

pa_orientation is the physical orientation of the sheet (pao_landscape means the sheet is physically rotated 90°), while printorientation is the orientation of the printed image on that sheet.

dso_initinternalcalc automatically evaluates the defaultexpression of internalcalc fields that have one while fetching, instead of requiring an explicit assignment in oninternalcalcfields for every record.

dtfo_utc: the value stored in the database is in UTC, converted to local time when the field is read and back to UTC when it is written.

Set dsgo_autofields to have the grid automatically show a column for every field of the bound dataset, instead of requiring datacols to be set up manually.

ek_loaded is posted, among others, when a form or datamodule has finished loading; components can also send their own object events, for example with tguicomponent.postcomponentevent.

When a tcustomface has a template, each of its properties that has not been explicitly set (i.e.

Set dialogkind to fdk_open or fdk_save before calling execute to choose the dialog's purpose (e.g.

MSEgui uses the same unified, Unix-style filepath syntax on all platforms (on a multi-boot setup, Windows drives can be mounted under the root, e.g.

Internal character representation for all text and filename elements in MSEgui is UCS2.

fs_selected is used in richstrings only.

fo_main makes the form the application's main GUI face and event receiver, and its icon the application's icon.
