I've looked at the events for the LookUpEdit (when used as the row editor in a VerticalGrid, so a RepositoryItemLookUpEdit) and don't see how to style rows in the dropdown conditionally, based on some other column's value in the row which corresponds to the displayed value.
For example, if an item listed in the dropdown has a currentStatus of "out of stock", it might be grayed out with strikethrough. The out of stock item cannot simply be excluded from the dropdown; it has to be in the list to make sense of historical data.
Is conditional styling possible with this particular editor?

The TableView still leaves a lot to be desired. Does anyone have a more complex example of a TableView that you would like to share? Here's what I'm missing:
Insert and Delete row:
Possible solutions:
press TAB on the last cell and new row gets inserted automatically
right mouse button -> context menu -> insert line (or delete line)
a table footer with table navigation and insert/delete buttons (like MS Access)
keyboard shortcut
...
Insert and Delete should be either at the current row position or at the bottom of the table. Of course the new row should be highlighted.
Copying / Duplication of rows inside the TableView
Copy selected cells to the clipboard
(solution exists: copy multiple cells to clipboard, paste into table is missing)
Insert a row with default values
Type to Edit: I don't want to have to doubleclick on a cell first in order to edit it. When you type on a cell, the table should automatically go into edit mode.
Navigation options like e. g. TAB = cell in next column, ENTER = cell in next row
Filtering should be possible via components inside the tableview, not via components (TextField etc) outside of it. A filter indicator (like the sort indicator) would be nice.
Changing the visibility of columns should be convenient, not via multiple clicks of the tableview menu button (for every column you have to click the menu button separately to show the available columns). The tableview menu button should be customizable
(solutions exist with reflection and without reflection)
Row and column headers should be possible
Validation of cells, so that when you are in edit mode and enter text instead of digits into a numeric cell you get the option to cancel the edit mode and revert to the default value
A (fixed) table footer which could e. g. show the sum for each column would be nice
Freezing of columns (there's already a Jira task for this)
Some of these were covered partially years ago from what I've seen. But I couldn't get a clear How-To impression and maybe things have changed with JavaFX8.
In case someone likes to contribute to any of these mentioned features, please share your thoughts. Thank you very much.
I have a combobox, on which I have to choose one option. That option determines which values should be shown on the comboboxes of a grid. The values to show on the grid's comboboxes are on a table. Right now, I'm showing all of them, but I need to filter it down.
The user must choose a value on combobox #1, and the comboboxes inside the grid (#2) should only show the related values. So far, I haven't been able to accomplish this.
Thanks in advance!
Refresh your drop down list as follows:
&l_field.ClearDropDownList();
/* select values required by sql */
&l_sql = CreateSql("...");
While &l_sql.Fetch(&l_key, &l_descr)
&l_field.AddDropDownItem(&l_key, &l_descr);
End-While;
I'm having a QTableWidget with 9000 data. I can search data from the table, like, if I search for '10', whole data starting with '10' will be displayed.
Now I need to highlight the first row, since it shows the accurate search result.
I'm using:
ui->tableWidget->setSelectionBehavior(QAbstractItemView::SelectRows);
for highlighting the selected row.
How can I highlight the first row of table?
I am not sure I am clear of why you need to set selection behavior unless you are planning for the user to be able to do the selection by clicking on the cells. And if you want that to be the default behavior then just set this as a property of the tableWidget when you use the QT designer.
But you can certainly do:
ui->tableWidget->selectRow(0);
That will highlight the row.
I created a Advanced Data Grid and implemented a grouping using GroupingCollection2 on it.
I implemented a custom Item Renderer and when I start to scroll horizontally, the cells belong to the previous item is also displayed on the group row.
Please take a look at the screenshot.
How can I tell from my item renderer that this cell is belong to a group and should not be displayed?
I'm trying to implement accessibility (keyboard only) ability on my site, but I'm having problems with Radio Button lists. When using radiobuttonlists, when initially, none of the radio buttons is selected, I am able to tab through every single value and select one upon hitting "enter". However, after a value is selected, I can only tab to the selected values, which presents a problem if I want to change the selected value.
From what I understand, radio buttons are grouped at the container controller level, thus when it is considered a group, only one can be selected at a time.
Any ideas on how to fix this issue?
Actually, this is not an issue at all. If a value is not selected, the browser will go through each value within the group. Once a value is selected, the browser will only jump to the chosen value within that group. Thus to change values within the group, the user is to use the keyboard arrows.
I believe you're correct about the RadioButtonList being one control (and therefore tabbing doesn't work). An alternative could be to create individual radio buttons and use the GroupName property to assign them all into one group. This should let you tab between them and still ensure they work in sync with each other.
