Name of macro that is used for generating certain attributes of this component. Please pay attention: the value of this attribute is read one time for each control and cannot be changed afterwards.
The attribute value must not be changed once the component is created.
Background color of the component. Any RGB value can be chosen using format #rrggbb.
| #FFFFFF | White |
| #000000 | Black |
| #FF0000 | Red |
| #00FF00 | Green |
| #0000FF | Blue |
| #0000FF30 | Blue with a transparency of x30. |
Background paint commands. There is a sequence of paint commands which can be executed one after the other by listing them as semicolon separated list. - By appending certain suffixes to a command you can define that the command is only executed in a certain situation. Available suffixes are: _empty (content of component is empty), _focus, _nofocus, _enabled, _disabled, _mouseover. Multiple suffixes can be used in parallel (e.g. write_empty_focus).

Spanning of columns if used inside a COLSYNCHEDROW.
| 1 | Control spans one column (default) |
| 2 | 2 columns |
| 3 | 3 columns |
Comment that can be asigned to any component. The comment is not operationally used.
| Any text | Any text |
Configuration information that is attached to this component. This information is not functionally used by CaptainCasa, but may be used for any application specific purpose.
Height of the control. Either defined as absolute value or as percentage value. Pay attention when using percentage sizing: the size refers to what is given from the components above. - When using components within a grid (FIXGRID) then the sizing of the component is completely managed by the grid, you do not need to specify any height in this case.
| 100 | 100 Pixels |
| 120 | 120 Pixels |
| 200 | 200 Pixels |
| 50% | 50 percents |
| 100% | Full available height |
Reference to image within your web application. The image either needs to be defined relative to the current page (e.g. ../images/abc.png) or needs to be defined in an absolute way (e.g. /images/abc.png). The root directory for absolute addressing is the directory of the web application.
| /images/abc.png | Image /images/abc.png |
| abc.png | Image abc.png |
| ../images/abc.png | Image ../images/abc.png |
Defines is images keep their width/height ration or if they are stretched to fit. Only has effect when either width or height is defined in addition.
| true | Keep ratio (default) |
| false | Fit size, stretch |
Reference to an outside object that is the content behind the component. E.g. a field is representing a certain field of a database table: in this case you could define the value table;column. The reference plays a siginficant role within the attributemacro management.
The attribute value must not be changed once the component is created.
| ref | One reference |
| ref1;ref2 | Two references |
| ref1;ref2;ref3 | Three references |
Flag that indicated if this component is rendered at all. If set to false then the component is not rendered - there is no component data sent to the client.
The attribute value must be an expression.
| true | Component is rendered (default) |
| false | Component is not rendered |
If more than one component is arranged within one row, then components need to decide how they want to be aligned vertically inside the row - in case the height of the row exceeds the height of the component itself.
| top | Top |
| center | Center (default) |
| bottom | Bottom |
In CaptainCasa you can define styles definitions for components. A style definition is a definition of a set of default attribute values that are applied to the component. In case you want to differenciate between different usage types of the component you can apply multiple styles - and use the stylevariant attribute to select between.
Vertical positioning of the content within the row.
| top | Top |
| middle | Middle (default) |
| bottom | Bottom |
Width of the control. Either defined as absolute value or as percentage value. Pay attention when using percentage sizing: the size refers to what is given from the components above. - When using components within a grid (FIXGRID) then the sizing of the component is completely managed by the grid, you do not need to specify any width in this case.
| 100 | 100 Pixels |
| 120 | 120 Pixels |
| 200 | 200 Pixels |
| 50% | 50 percents |
| 100% | Full available width |
