My app allows double-clicking on a QTableWidget cell to edit the content. However, when I double-click on a cell, the existing content is selected.
How can I allow a cell's content to be edited without having the existing text automatically selected?
Qt item views automatically call selectAll() when an editor is created and it's a QLineEdit or a Q[Double]SpinBox.
Since the call to selectAll() is done after the editor is created, a simple solution would be to connect to the selectionChanged signal and deselect the text automatically. This can be done in an item delegate that would just override createEditor().
Note that this must be done only once, otherwise any user selection would become impossible. This also means that the signal must be disconnected immediately, and before deselecting (otherwise the function would be called again).
class NoSelectDelegate(QStyledItemDelegate):
def createEditor(self, parent, option, index):
editor = super().createEditor(parent, option, index)
if isinstance(editor, (QLineEdit, QSpinBox, QDoubleSpinBox)):
def deselect():
# Important! First disconnect, otherwise editor.deselect()
# will call again this function
editor.selectionChanged.disconnect(deselect)
editor.deselect()
editor.selectionChanged.connect(deselect)
return editor
# ...
table.setItemDelegate(NoSelectDelegate(table))

I have a Content Control inside a header in Word in which I have a date time picker. I'm trying to fire the _ContentControlOnExit event when the user leaves the focus (blurs) of the picker.
Let's suppose I've manually created a Content Control and I've assigned it a Date Picker. I've also tagged it with the value date.
I want that each time the date is changed, I perform a subroutine that will insert a text value to another ContentControl tagged tide-level. I tried the code below with no success.
Please, note that the date ContentControl is inside a header in the Word Document.
Private Sub ActiveDocment_ContentControlOnExit(ByVal ContentControl As ContentControl, Cancel As Boolean)
If (ContentControl.Type = wdContentControlDate) Then
MsgBox "Let's do it! Write the tide levels"
dateObj = ActiveDocument.SelectContentControlsByTag("tide-level")
dateObj.Range.Text = "wwwoohooo Tide Levels!"
Cancel = True
End If
End Sub
I remember reading somewhere that whenever you have content in the header, it seems things get problematic...
Any ideas?
P.S:
Currently using Word 365 - VBA
Based on the name of the procedure in the question - ActiveDocment_ContentControlOnExit - it appears the event handler was not generated automatically by Word and that it is therefore not in the ThisDocument class module of the document that contains the content controls. The name of the event handler (generated by the VBA editor) is usually Document_ContentControlOnExit.
The content control event handlers must be in ThisDocument. Theoretically, they could be typed manually, but Word doesn't always recognize manually typed event handlers. So it's better to use the VBA Editor's automatic "stub" generation to get the structures:
Open the ThisDocument module for the document that contains the content control.
In the code page window, at the top left, select "Document" from the drop-down.
from the top-right select the event to be inserted.
At this point, the VBA editor will create the "stub" for you - all that's needed is the code to be executed.
Note about the content control being in the header: This event does fire as long as focus when exiting remains in the header. If, however, the user double-clicks in the document body in order to exit the header the event doesn't fire. (At least, not in my tests.) If this is a problem you may want to put this field in the body of the document with a second, linked content control in the header to reflect the selection. Doing this is a bit complex (requires a Custom XML Part in the document to manage the linked information), but the version of Word you're using should have a tool for setting it up.
the macro name should be:
Docment_ContentControlOnExit
NOT:
ActiveDocment_ContentControlOnExit
I'm using Android Studio and I have code completion enabled as in picture.
I have enabled "Autopopup code completion" and "Insert selected variant by typing dot, space, etc..".
I want to write:
Drawable d = new BitmapDrawable(....);
I write "Dr", appears the popup, I click the space bar, and it writes "Drawable". It's all ok.
Then I write "d", appears the popup with "drawable" suggested, I click the space bar, and it writes "drawable".
But I want to write "d".
Is it possible to change this option applying only to classes and methods and not to new variables?
There is not a way to have code complete only apply to classes and methods and not to new variables. You have three options:
Turn off the Insert selected variant by typing dot, space, etc." options. You will then need to use Enter (to insert) or Tab (To overwrite) when you want to select an item from auto complete. The . (period/dot) key will still work when completing classes if you want to invoke a static member. (This is likely the best of the three choices and is the default behavior.)
After you type d for the variable name, hit Esc to close the auto complete popup before you hit the Space.
Turn off "Autopopup code completion" so that you have to manually activate it each time via Ctrl+Space
A user is editing a value in a property grid, then he clicks a button outside the property grid which executes code to read the property values. Sometimes the OLD value of the property is read, rather than the new value which was being edited. I have to tell the users that they must complete the editing, by hitting return or clicking on another property before clicking any buttons outside the grid. They forget, and report a bug.
I would like to make this foolproof. Perhaps by forcing the current edit to complete when the mouse leaves the property grid.
I know how to handle the mouse leaving event. I do not know how to force the property grid to accept any partial edits.
I have tried, as a hint to the user,
pg = new wxPropertyGrid( ...
....
if( ! pg->EditorValidate() )
{
SetStatusText("Please complete editing");
return;
}
but EditorValidate() always returns true
Found it!

Using Xcode 5.* for a cocoa-applescript automator action.
Interface is a a simple popup menu that gets populated using an outlet with:
tell thePopupMenu to removeAllItems()
tell thePopupMenu to addItemsWithTitles_(theList)
When the action is used in a workflow (a Service actually), I want the next time it is run and the action dialog shows up (I will have "Options:Show when run" selected), I want the popup menu to change the selection to the last one that was selected. Right now, the default first item shows, even though last time it was run, the user selected a different item in the popup menu.
My thought was that I need to capture a change in the popup menu with a Sent Action handler, and then set some type of default. I have a working handler:
on thePopupMenuSentAction_(sender)
set popupValue to (popupSelectedValue of my parameters()) as string
-- save this selection somewhere???
end
What's the right way to save this? Do I use User Defaults? My Bindings are currenly all tied through Parameter object/controller. If I should use User Defaults, can someone give example code for setting up User Defaults, and then how to get and set a new value using Cocoa-Applescript?
If I can get the name string of the menu item saved somewhere, I can get the string and then change the selection of the popup menu in the
on opened {}
-- set up the action interface
end
handler which gets called just before the action is displayed each time.
Thanks for any help,
Joe
I did mine a bit differently. I will assume you are referring to what XCode calls a "pop up button" (somewhat misleading). I did not use the parameters at all, although that is probably better for larger projects. Have a look at the code:
script Insert_Picture_into_Powerpoint_Slide_Show
property parent : class "AMBundleAction"
property menuChoices : {"Insert a Beginning", "Insert at End"}
property menuSelection : missing value
if (menuSelection as string) is "missing value"
set menuSelection to 0 as integer -- sets default value
end if
end script
I bound Content Values to File's Owner and under Model Key Path I put menuChoices.
Then you just bind the Selected Index to File's Owner and for the Model Key Path type menuSelection.
Defaults
On the initial run, if the user does not click anything, the menuSelection will be missing value. Because I couldn't find a way around this, I created a conditional which tests for this and sets it to the first choice by default (the one that is shown when you add the action).
When the user selections one of the menu choices, the choice is remembered on sequential runs.
I have a standard form in MS-Access which lists a bunch of orders, and each row contains order no, customer, etc fields + a button to view notes and attached document files.
On request from our customer we should gray out the button btnAnm (or check or uncheck a checkbox) depending on a calculation from two queries to two other tables (a SELECT COUNT WHERE and a check if a text field is empty).
I've tried btnAnm_BeforeUpdate(...) and btnAnm_BeforeRender(...) and put breakpoints in the subs, but none of them trigger. The same if I use the control Ordernr instead of btnAnm.
I'd like a function in the Detail VBA code to be triggered for each "Me." (row) so to speak, and set the row's control's properties in that sub.
What do I do? I've looked at the help file and searched here.
*Edit: So I want to do something that "isn't made to work that way"? Ie. events are not triggered in Details.
As an alternative, could I base the value of a checkbox on each line on a query based on the 'Ordernr' field of the current row and the result of a SELECT COUNT from another table and empty field check?
Do I do this in the query the list is based on, or can I bind the extra checkbox field to a query?
A description of how to do this (combine a COUNT and a WHERE "not empty" to yes/no checkbox value) would be perfectly acceptable, I think! :)*
You cannot do much with an unbound control in a continuous form, anything you do will only apply to the current record. You can use a bound control with a click event so that it acts like a button.
Presumably the related documents have a reference to the order number that appears on your form, which means that you can create a control, let us call it CountOrders, with a ControlSource like so:
=DCount("OrderID","QueryName","OrderID=" & [OrderID])
The control can be hidden, or you can set it up to return true or False for use with a textbox, you can also use it for Conditional Formatting, but sadly, not for command buttons.
Expression Is [CountOrders]>0
You can also hide the contents and add a click event so that is acts in place of the command button. Conditional Formatting will allow you to enable or disable a textbox.
As I understand your question, you have a continuous form with as command button that appears on each row - and you'd like to enable/disable the button conditionally depending on the contents of the row.
Unfortunately you can't do that. It seems that you can't reference the individual command buttons separately.
Having wanted to do something similar in the past I came up with two alternate ways of setting up my interface.
Put a trap into the onClick code for the Button. Which is icky, because it is counter intuitive to the user. But it gets you that functionality now.
Move the command button (and editable fields) up into the form header, and make the rows read only. Your users then interact with the record only in the header, and select the record they want work with in the list below. As I recall this is known a Master-Detail interface.
