For example, such parameters could be the log level, the look and feel, a username, etc. There are various different ways to define application parameters, depending on the technology that is used: text/html 2020-06-08T13:25:06+00:00 https://doc.sibvisions.com/jvx/client/gui/bind_editors_model?rev=1591622706&do=diff Editing of data in a database application should be possible directly in a table as well as via forms. Form-based entry increases clarity and allows grouping that is difficult when using tables. The active model of JVx allows the displaying and editing of data in many different ways, regardless of whether the data is a table, a graph, or a text editor. In all cases, the data is governed by the model. Changes in the model affect all registered components. Therefore, the displayed data is alwa… text/html 2024-11-18T10:31:41+00:00 https://doc.sibvisions.com/jvx/client/gui/celleditor_dateformat?rev=1731925901&do=diff To set a custom date format on a date cell, simply use following code: UIDateCellEditor dateEditor = new UIDateCellEditor(); //use long pre-configured date format dateEditor.setDateFormat(((SimpleDateFormat)SimpleDateFormat.getDateInstance(SimpleDateFormat.LONG)).toPattern()); text/html 2020-07-08T17:35:05+00:00 https://doc.sibvisions.com/jvx/client/gui/celleditor_popups?rev=1594229705&do=diff JVx' standard behavior for starting cell editing is a double click on the table cell. The double click opens the editor and allows typing. If the cell contains a linked cell editor or date cell editor, you have to click on the small “down” arrow to open the popup (also key down works). text/html 2020-06-26T11:53:41+00:00 https://doc.sibvisions.com/jvx/client/gui/checkbox?rev=1593172421&do=diff If you need native checkboxes that are automatically bound to your model, instead of fake "ChoiceCellEditor checkboxes", you can use UICheckBoxCellEditor. However, be aware that such native checkboxes only have two states and two values (selected or unselected, e.g., Y or N). You can't set a custom value for null/empty, but this would be possible with UIChoiceCellEditor. text/html 2020-06-15T10:08:19+00:00 https://doc.sibvisions.com/jvx/client/gui/choice_celleditor?rev=1592215699&do=diff JVx has checkboxes defined with ICheckbox, but such checkboxes are not automatically bound to the model. It's possible to bind checkboxes manually and update the state after value-changed events. If you need a checkbox automatically bound to the model, an IChoiceCellEditor is the class to use. text/html 2020-06-26T11:56:33+00:00 https://doc.sibvisions.com/jvx/client/gui/column_width?rev=1593172593&do=diff The column width can be set via ColumnDefinition, e.g., dataBook.getRowDefinition().getColumnDefinition("FUNCTION").setWidth(231); The table uses this width for the cell width.

The table has one or more columns, and it's possible to choose one value from the table as display value. Here's an example: The combobox is a very special control because not all GUI technologies show more than one column in a combobox. In desktop technologies like Swing, it's not a problem to show more than one column. In web technologies, it's unusual to show more than one column.

This makes it possible to provide the application on various different platforms. The framework currently supports the following UI technologies: * Swing * Vaadin * Headless To launch an application using a certain platform, all we have to do is use the appropriate launcher. The launcher definition depends on the used technology. If you use Swing, all you have to do is to set a command-line argument.

Another reason could be that a workscreen shows different dialogues on button clicks. text/html 2024-11-18T10:42:08+00:00 https://doc.sibvisions.com/jvx/client/gui/custom_factory?rev=1731926528&do=diff Sometimes you need additional methods in your UI factory, e.g., create custom controls or preconfigure existing controls. The UI factory is one of the first classes that is instantiated from a launcher. If you need a custom factory, use an application parameter to configure it. text/html 2020-06-26T11:54:01+00:00 https://doc.sibvisions.com/jvx/client/gui/custom_linked_celleditor?rev=1593172441&do=diff With JVx, it's very easy to define dropdown list boxes, LOVs, or picklists.

Usernames are a good example. After successful login, the username is saved at the client and is then used to populate the input field at the next launch of the application. text/html 2021-07-08T10:48:48+00:00 https://doc.sibvisions.com/jvx/client/gui/screen_parameters?rev=1625741328&do=diff A works-creen parameter is useful if you want to transfer information between screens. If you have a persons screen and it opens opens the contact screen, it would be useful to know the selected person in the contact screen. This is only one use-case another use-case could be that you control the layout of a screen. If you open a screen as popup, it could be useful to know that the screen is in popup mode. text/html 2020-06-26T11:54:38+00:00 https://doc.sibvisions.com/jvx/client/gui/screenshot_clipboard?rev=1593172478&do=diff JVx has a simple mechanism to create “screenshots” from components or the entire application.

It's no problem to create or use a variable to save such information. This is also the recommended solution because it makes the code readable and references can be found.

Since JVx already offers swing implementation of the user interfaces, you cannot only directly integrate JVx´s swing components in your applications, but also integrate any swing component in JVx, or simply use it, without adaptation and implementation efforts.
