The component HEXIMAGE renders an image. The image is not passed as URL, but the bytes of the image are directly passed.
Use the component if an image e.g. is loaded from database.
The bytes are passed as hexacdecimal String (e.g. "f4c366..."), use the function ValueManager.encodeHexString(byte[]) in order to convert bytes into an hex string representation.

noborder | Defines that no border is painted - esp. in cases when empty borders are normally added (e.g. in grid cells) |
Name that is assigned to the component at client side: there is no specific function associated with the name - but it can be used on client side to describe the component in a clearer way. The name is e.g. used by UI test tools that replay certain user interaction sequences - and that reference components via their name.
In case the space provided by the container (e.g. gridlayoutcontainer) for the component is wider than the component itself: definition where to place the component
left | Left (default) |

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.
If set to true then an event is triggered on server side when the user starts a drag operation. The event is of type BaseActionEventDragStarted.
false | No event triggered (default) |
true | Event triggered |
Description of object that can be dragged from this component. The description consists out of a type and and id. A component may have multiple objects that can be associated.
article:4711 | Example: article |
file:harry.txt;content:Hello world! | Example: Multiple object descriptions |
Text that is shown when dragging over the component. The text is only shown if a drop is possible (DROPRECEIVE definition).
(default) No text shown | |
pixel(5) Current drop pixel position - in steps of 5 (or any other value) | |
pixelX(5) Current drop pixel position - only the x-position | |
pixelY(5) Current drop pixel position - only the y-position | |
percentage(5) Current drop pixel position as percentage number - in steps of 5 (or any other value) | |
percentageX(5) Current drop pixel position as percentage number - only the x-position | |
percentageY(5) Current drop pixel position as percentage number - only the y-position | |
textX(0,left,25,middle,75,right) Text that is shown depending from percentage x-position |
Semicolon separated list of object types that can be dropped onto this component.
article | Example: articles can be dropped |
article;customer | Example: articles and customers can be dropped |
Defines if the component is focusable. The default depends on the component: typical input components (field, check box, ...) are focusable by default, while typical structure components (pane, label, ...) are not focusable by default.
true | Focusable |
false | Not focusable |
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 percentage sizing then you may define a minimum size in addition, by appending it with a semicolon: "100%;100" means: use 100%, but always keep a minimum size of 100. If using absolute sizes you may append a "+" to define, that the size is extended if required by the component. - Please note: the sizing may be completely taken over by the parent component (e.g. if a component is used in a grid cell), in this case the size definintions on this component level are obsolete.
100 | 100 Pixels |
120 | 120 Pixels |
200 | 200 Pixels |
50% | 50 percents |
100% | Full available height |
Help id that is part of the online help management.
helpid | Id pointing to a server side online help file. |
ccnof1help | Explicitly switching off default F1 help. This is sometimes required in case you want to explicitly react on F1-key as hotkey. |
Binary data of image, converted into a hexadecimal string. User ValueManager.encodeHexstring(byte[]) in order to convert binary data into a string representation.
Client side event that triggers a server invoke.
click | Mouse click (both mouse buttons) |
leftclick | Mouse click (left mouse button) |
rightclick | Mouse click (right mouse button) |
doubleclick | Mouse double click |
leftanyclick | Both click and double click are transferred, check event BaseActionEventInvoke on server side for click count |
mousedown | Left mouse button down |
Defines is images keep their width/height ratio 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 |
Reference to the id of a POPUPMENU definition that is available either in this page or in a page that includes this page.
If set to true, then an explicit roundtrip is triggered when the user presses the right mouse button in order to open a popup menu. As result you can define the popup menu dynamically (using DYNAMICCONTENT) and prepare the popup menu at this point of time when the user want to open it.
false | Menu is already defined in layout, no roundtrip (default) |
true | Menu is dynamically created, roundtrip is triggered |
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.
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.
true | Component is rendered (default) |
false | Component is not rendered |
Rounding radius of edges of border/background. This is optical rounding - so has nothing to do with mathematical rounding...
0 | Straight edges |
5 | Rounding with radius 5 |
10 | Rounding with radius 10 |
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.

bottom | Bottom |
Spanning of rows if used inside a GRIDLAYOUTPANE.
1 | Control spans one row (default) |
2 | 2 rows |

Shadow of component. The definition is done by several inner values: hoffset, voffset, blur and color.
hoffset:5;voffset:5;blur:5;color:#C0C0C0 | full shadow definition |
color:#C0C0C0 | Definition only via color, rest of values is set to default values |
Style class names that are applied to this component.
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.
Text that is shown as hint when the user stays with the mouse on top of the control for a while.
...anytext... | Text that is displayed as tooltip. |
server:true | Indicator that tooltip for the component is managed on server side. The actionListener will be invokde with events BaseActionEventTooltipStarted and BaseActionEventTooltipEnde. On server side you may implement some modeless popup in order to show some more complex tooltip |

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 percentage sizing then you may define a minimum size in addition, by appending it with a semicolon: "100%;100" means: use 100%, but always keep a minimum size of 100. If using absolute sizes you may append a "+" to define, that the size is extended if required by the component. - Please note: the sizing may be completely taken over by the parent component (e.g. if a component is used in a grid cell), in this case the size definintions on this component level are obsolete.
