I'm working with Fiori elements, and in the ObjectPage I want to display a table inside a section. For this table I have a column as a boolean type.
Is it possible to manage this column as a checkbox by annotation, or some other way? If so, how?
I am not sure why it should not be possible. Since a checkbox basically has two states, it should be able to handle the boolean variables very well. Care to explain more about what exactly you want to achieve?
When using Fiori Elements currently a boolean value is displayed as text.
Expect you are in edit mode - then a checkbox is rendered.
So, the answer is 'No' for display mode and 'yes' (by default) for edit mode.
I need to slightly modify a ag-grid row after it has been rendered. In ag-grid, the actual HTML elements are not necessarily persistent, so manually-set styles may fall off.
For one thing, I have to modify the selection checkbox to set its tabindex to -1. This can technically be done in the cellRenderer callback, although it looks quite hacky. (The checkbox can be found at params.eGridCell.children[0].children[0].wrappedElement.)
But I also have to add a CSS class to some rows to highlight them based on external criteria. I haven't found a way to do this at all.
The best solution would seem to be using some sort of after-rendering callback, but to my knowledge no such thing exists.
I found a couple of related questions, but they were both resolved via cellStyle, which would not suffice here:
Row formatting in ag-Grid
How to provide a background color for an entire row in ag grid based on a certain value in a column?
You have not 1 but 3 options:
getRowClass(params):
Callback version of property 'rowClass'. Function should return a string or an array of strings.
getRowStyle(params):
Callback version of property 'rowStyle'. Function should return an object of CSS values.
processRowPostCreate(params):
Allows you to process rows after they are created. So do final adding of custom attributes etc.
In this last one you have the row in params.eRow.

sap.m.RadioButton has got only Text attribute and does not have a Value attribute.
While I can work around this by using custom data, is there anything I am missing? sap.ui.commons.RadioButton has got a key field.
Also, what is good way to bind a value to a Radio Button Group(with sap.m.Radiobutton controls) in XML View
The "selected" property of sap.m.RadioButton is what you are looking for. Documentation
I'm using gxt 3.0.1 and I have Basic Grid added on my form.
Now I've added filter for each column which can be used over TextBox in menu of grid columns (basically it's Filter Grid now).
I have to make my own TextBox above grid and apply filter to it. And do that for each column of grid.
Filtering is done locally.
My idea was to look for code they made for their TextBox and apply it on mine TextBox.
But I failed.
It should be just String filter, which should work exactly as filter provided in Filter Grid.
Also I'm using UiBinder.
From the GridFilters javadoc
* Filtering is adjusted by the user using the grid's column header menu (this
* menu can be disabled through configuration). Through this menu users can
* configure, enable, and disable filters for each column.
This is meant to be used to configure column header menus to have filters built in, not set up text boxes outside of the grid - see http://www.sencha.com/examples/#ExamplePlace:filtergrid for how this is intended to work.
To build the way you are describing, start instead with making a StoreFilter object based on the contents of the TextBox, adding it to the store, and re-applying the filter each time the contents of the text box change.
Check out StoreFilterField for a working example, or follow the above instructions to build your own.
If this doesn't work, please provide a code sample in your question...
I am trying to create a simple GUI with table containing x and y coordinates of samples. I use treeview, and I want the cells of the table to be editable by user. Is it possible to specify if the cells should be editable directly in Glade in cellrenderer properties, or do I have to specify it in my code? I use Glade 3.6.1
I have just found out that unticking box "Editable" in the Tree View Editor when editing my treeview, enables me to specify whether the cells shall be editable or not, because if the box is unticked, the cells editable property is no longer connected with the model.
But if I run the program, cells are editable, but the value that I write inside disappears. How can I fix that? Why doesn't the cell store the value I type inside?
Thanks for any hint
For anyone dealing with a similar problem, I have solved it - whenever a cell is edited, appropriate record in the model needs to be changed, example code in Python:
cell.connect("edited", self.text_edited, model, column)
def text_edited( self, w, row, new_text, model, column)
model[row][column] = new_text
I found I had to do something just a little different, but I am also using Ubuntu's Quickly development environment. I did have to go into Glade and uncheck the "Editable" box in my cellrenderer, which then brought up a toggable "Yes/No" button. Then my code looks like:
#psuedo-code function definition
cellcolumn_widget.connect("edited", self.function, list_or_treestore, columnnumber)
#actual code, editing second column so column is passed as 1
self.builder.get_object("cellrenderer_chapter").connect("edited", self.cell_edited, self.builder.get_object("liststore_chapters"),1)
def cell_edited(self, widget, row, new_text, model, column):
model.set_value(model.get_iter(row),column,new_text)
for python GTK, by default, text in Gtk.CellRendererText widgets is not editable, you can change this by setting the value of the “editable” property to True:
renderer = Gtk.CellRendererText();
renderer.set_property("editable", True);
then you can connect to the “edited” signal and update your Gtk.TreeModel and/or database accordingly:
renderer.connect("edited", self.entry_edited);
def entry_edited(self, widget, path, text):
self.listStore[path][number_of_row] = text; # put the number_of_row to be edited
