Component CAMERA

Overview

The CAMERA components accesse the system's camera and is able to take photos. The photos are sent to the server side where you can process them within your application.

Pay attention: the component only can be used in https-environments for security reasons! And: of course the component requires some acknowledgement by the user.

If set to true then changes of the width/height of the component are animated.

trueWith animation
falseWithout animation (default)

attributemacro

background

Background color of the component. Any RGB value can be chosen using format #rrggbb.

#FFFFFFWhite
#000000Black
#FF0000Red
#00FF00Green
#0000FFBlue
#0000FF30Blue with a transparency of x30.

border

Defintion of border of control. Either defined as straight color value, with then having a border of 1 pixel. Or: an explicit per-side definition as comma separated list of border definition values.

noborderDefines that no border is painted - esp. in cases when empty borders are normally added (e.g. in grid cells)

clientname

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.

focussequence

Explicit definition of tab sequence. The format of the definition is GROUP/SEQUENCENUMBER. You can define any number of tab-groups within one page. If the user tabs into a component with a FOCUSSEQUENCE definition then the next tab will focus the next component belonging to the same GROUP and holding the next SEQUENCENUMBER. - By default the FOCUSSEQUENCE value is prefixed with some page-id before being sent to the client so that definitions of one page do not affect definitions of another page. You can explicitly avoid this prefixing by using the naming convention ccfix_GROUP/SEQUENCENUMBER.

---------- Examples -----
A/1Example: group A, sequence 1
A/2Example: group A, sequence 2

height

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.

popupmenu

Reference to the id of a POPUPMENU definition that is available either in this page or in a page that includes this page.

popupmenuloadroundtrip

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.

falseMenu is already defined in layout, no roundtrip (default)
trueMenu is dynamically created, roundtrip is triggered

reference

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.

refOne reference
ref1;ref2Two references
ref1;ref2;ref3Three references

rendered

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.

trueComponent is rendered (default)
falseComponent is not rendered

requestfocus

Indicator, by which you can control the focus to be moved into this component.

creationComponent requests focus when created.
...int value...Counter coming from server side. Please check Developers Guide.

requestfocushotkey

Hotkey definition that is used request the focus for this component. The hotkey is globally available within the corresponding dialog.

rounding

Rounding radius of edges of border/background. This is optical rounding - so has nothing to do with mathematical rounding...

0Straight edges
5Rounding with radius 5
10Rounding with radius 10

rowalignmenty

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.

topTop
centerCenter (default)
bottomBottom

rowspan

Spanning of rows if used inside a GRIDLAYOUTPANE.

1Control spans one row (default)
22 rows
33 rows

shadow

Shadow of component. The definition is done by several inner values: hoffset, voffset, blur and color.

hoffset:5;voffset:5;blur:5;color:#C0C0C0full shadow definition
color:#C0C0C0Definition only via color, rest of values is set to default values

styleseq

Style class names that are applied to this component.

stylevariant

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.

tooltip

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:trueIndicator 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
server:true;opendelay:1000Duration in milliseconds after which a tooltip event is triggered when the user moves the mouse on top of this component

width

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.

focusgainedwith focus events but only for gaining the focus
focuslostwith focus events but only for loosing the focus

x

x-pixel-position: this attribute is only used if the component is directly placed into a PAINTAREA!
