It's a longshot that anyone can help with this, but here goes. I inherited a VB6 app with a Janus GridEX control. It iterates through records, and is editable. Problem is, if I edit a cell and hit the button to go to the next record, the change is applied to the next record, not the one I was editing. It's like, I need it to finish up the edit before going to the next record. I've had this sort of problem before in VC++, and sometimes you have to "KillFocus" on the control you're on or something. I just don't know what to do here. I tried sending a carriage return, since if you return out of the edit cell, it works, but sending a carriage return manually doesn't work. What's the secret?
Is your grid bound or unbound?
It's hard to tell from your description, but I imagine that if your are having this problem then it's probably bound.
As the other answer asked, is the button the RecordNavigator that is built into the control or is it a separate button? The reason I bring this up again, is that I have seen issues in the VB6 applications I support where a toolbar will often intercept and interfere with how the JanusGrid should work.
To get around this limitation, I have added the following code in the click handler of any toolbars where there is also a JanusGrid control on the form.
If jsgxYourGridName.EditMode = jgexEditModeOn Then jsgxYourGridName.Update
This way any changes are immediately applied to the current row.
If this does not help, then I have also seen problems where the recordset that is bound to the grid gets out of sync with the internal recordset in the grid. You can check this by comparing the bookmark of the grid to the bookmark of the recordset.
Ie. mrsYourRecordset.Bookmark = jsgxYourGrid.ADORecordset.Bookmark
At one point I may have also used something like this.
jsgxYourGrid.ADORecordset.Bookmark = jsgxYourGrid.RowBookmark(jsgxYourGrid.RowIndex(jsgxYourGrid.Row))
Finally you can try setting a breakpoint in the BeforeUpdate, RowColChange and/or AfterColUpdate events of the grid, to see what record the grid is really on when clicking on the button.
It depends whether the button is internal to Janus GridEX or not. If it internal then just about the only thing you can do is look at the events the control exposes to see if there a sequence that can let you know that this problem occurs. Then you can try to take corrective action by restoring the row you moved to and put the edit in the row you left.
If the button is external to Janus then you can use the debug mode to trace sequence of statement that control the transfer of focus to the next row. It could be something out of order or a side effect of the particular sequence of commands. I have run into both with different controls.
Remember that you can edit while in debug mode so you can try different approaches and test until you find one that works.

I've added some code as found here Big problems with MFC/WinAPI to colour tab titles the same as the reset of the dialog, which works, but unfortunately all the tabs end up with the same name. This doesn't surprise me all that much as GetCurSel() is used to grab the text to use, and only one tab can currently be selected, but I'm struggling to see how you access the correct tab index from OnDrawItem().
I've googled and had a look on MSDN but don't see how anything passed to OnDrawItem lets you know which tab is currently being drawn, rather all the examples I've seen assume you're only interested in the one currently selected. All I want to do is something along the lines of GetWindowText() on the child window and redraw with that. I'm also unsure of the parent/child/sibling relationship between the sheet, tab control and page - it depends who you listen to.
I should probably add that I'm also unsure why all the tabs are redrawn when I select one. I don't know if this is normal or something specific to this implementation (that's something I'm looking at, but like seemingly everything else in this code base it's multiply inherited several times over ...).
Cheers for any help.
Not to worry, I now realise lpDrawItemStruct->itemID holds the tab index so I can get a handle to the tab using that.
In child window of my application, I have placed one single line edit control named as sle_name. Its tab order is 1.
Below that control I have placed DataWindow having formatted as free form style.
When I run the app, if my focus is in sle_name, and I click on sle_name then rbuttondown event is triggered. Then I move my focus to DataWindow(dw_account). Once I got focus on dw_account and then if I try to click on sle_name, my focus is not moving on sle_name and neither I can run rbuttondown event on sle_name.
What is the reason for this problem?
One more thing: when I start this window my focus in set in sle_name, from that control if I press tab key then my focuse moves to dw_account and if I press again shift+tab then my focus is moved back to sle_account.
But if I try to set focus from dw_account to sle_account using mouse pointer it is not moving focus.
What is the reason behind this behaviour?
I had the same behavior in a child window.
It was fixed when disabled the 'ControlMenu' and 'TitleBar' properties in the window. (It's so strange).
Hope it helps

This isn't natural behaviour, so the cause is likely something you've scripted. Depending on your architecture, the culprit code could be a number of places (e.g. framework objects). If this were my problem, I'd run with the PBDEBUG trace turned on (a System Option in the IDE, or /PBDEBUG on the command line after the deployed EXE name), and see what is firing when you try to move back to the SLE.
I'd also be using PBL Peeper to see the trace and the code side-by-side, so it's easier to see what code is being executed (the trace only shows you script name and line number).
Good luck,
Terry.
you must have to create the event ID pbm_lbuttonup, with the same parameter as rbuttondown event. Then in the code you write this.setfocus()
I am drawing the GUI using GTK+ with PyGTK.
I've created a ComboBox within a TreeView. But the problem is that when I first click an item, the dropdown arrow is insensitive (grayed-out). I had to click another item and then return to the item again to for the dropdown arrow to be sensitive again.
Is this standard for ComboBox in TreeView? If you have a fix in any other language, I can accept it as well.
An example can be found here.
He is facing some other issues but his code demonstrates the problem as well.
The problem with the code you are referring to above seems to be that the ComboBox actually only has 1 element when you start editing, which makes drop-down feature useless (and hence inactive). To make it behave as I suspect you wish, all you have to do is use another signal to execute self.populate_combo. I added two lines after the treeview was created to make it work:
treeview = gtk.TreeView(liststore_hardware)
sel = treeview.get_selection()
sel.connect("changed", self.populate_combo)
That is, I made the changed selection cause population of the Combos, which implied that they had more than one element in them when control was returned to the main-loop. And hence drop-down worked.
I also commented out the previous editing-started signal since it added nothing with the current structure of the program.
window.connect("destroy", lambda w: gtk.main_quit())
#self.cellrenderer_combo.connect("editing-started", self.populate_combo)
self.cellrenderer_combo.connect("edited", self.combo_changed, liststore_hardware)
Edit:
On second thought, the model is a None after __init__ has been run and not 1-length per row as I wrote above, which makes the lack of dropdown-features even more reasonable.
Comment:
The code you referred to and my change to it are both only rational if changing rows (or editing) causes a drastic need to rewrite the ListStore. I'm not really sure what type of scenario would demand that. If, on the other hand, the contents of the TreeView and the ComoBox' ListStore varies as a result of a search-action or filtering done else-where, then that search, rather than the change of rows should invoke populate_combo.
So an alternative solution in the scope of the code at hand, my suggested event above can also be commented out and a simple
self.populate_combo()
be added as the last line of the init function.
Further, should there be a need to re-populate the combos during the run of the app, I would suggest that the current ListStore is modified rather than creating a new one each time, if the changes are not expected to be major (in which case make a new is probably fastest and simplest).
I have recently been asked if I could make a macro in Excel VBA that will allow a user to type in two numbers and have it automatically drop to the next row. The purpose of this is so they can type in grades for a test two numbers at a time without pressing enter since they aren't great at typing.
When I first heard this he mentioned it was Visual Basic, so I figured I'd just use a TextChanging or TextChanged event in the cell range and have it work off that. However, I haven't been able to find any such event or anything resembling it in the documentation thus far. The first thing that I came across was Workbook_Change, but that only changes after you press enter which is useless to me. Someone else mentioned there is such an event, but couldn't name it directly and I haven't been able to find what they were talking about.
If anyone has any information on if such an event exists or is possible I'd love to know.
The Excel version is 2007 as far as I'm aware.
This, in my opinion, requires a non-programming solution. I absolutely sympathize - it is tough to watch people get old - but you have to draw the line somewhere - for their sake and yours. The enter key is the most basic part of a computer. You could probably write a macro that would automatically hit enter on every even(or odd depending) keystroke in excel - but you're going to run into other problems like not being able to use delete normally. And what if you do want to put a string of text in a cell(like the student's name)? Perhaps it is time to find a non-programming solution. By that I mean someone should have a candid conversation with him about how he wants to solve the problem. Personally, I would offer to type the numbers in for him, as I am accustomed to the number pad - but it is probably better to be more direct and start to discuss retirement.
See this discussion about the limitations of cell edit mode in excel:
http://www.mrexcel.com/forum/excel-questions/524860-call-macro-every-keystroke.html
If you're really heart-set on a programming solution, I would recommend some kind of keystroke logging add-in.
Good Luck.
You could use the Worksheet_SelectionChange event. It is triggered without enter, but it would be triggered a lot.
You could however also create a special user-form for typing in the data, but this might be more work than necessary.
The main problem with using my suggested event is, you will need it as trigger and trigger it yourself, when selecting the next row, so disable event handling before changing the selection.
Edit:
This is a quick solution (paste this into the vba-code of the desired worksheet):
Private Const clngColumnRightToLastGrade = 5
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Column = clngColumnRightToLastGrade Then
Application.EnableEvents = False
'offset selection, one row down, two cols to left
Target.Offset(1, -2).Select
Application.EnableEvents = True
End If
End Sub
This will set you one row down and to column C, everytime your selection changes to column E (=5).
You don't have to use a constant of course, you could specify the column to sense in the workbook, so your user might modify it easier by himself.
To make this as an optional feature, you could extend it to autogenerated code. What I have in mind is like a Ribbon-Button, which opens a setupForm to configure, and a Ribbon-Button to activate the configuration, which would place this code in the configured sheet. But this might be a bit over the top.
In Excel 2003, (may be different in Excel2007 ?!) the WorkSheet_Change event is triggered every time the value of a cell is changed wether it is by pressing enter, delete, selecting an other cell after modifying a cell or even when a vba script changes the value of a cell.
I would do something like that:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim RefRange As Range
Set RefRange = Intersect(ActiveSheet.Columns("??????????"), ActiveSheet.UsedRange)
If Not Intersect(Target, RefRange) Is Nothing Then
Target.Offset(0, 1).EntireColumn.Range("A1").Select
'Target.Offset(0, 1).EntireColumn.Range("A65536").End(xlUp).Offset(1,0).Select
End If
End Sub
I have a project that I'm working on that has a TreeView Control in it. For everything underneath Level 1, those nodes are being used as a bookmark function, so we want a Tri-State CheckBox there. I found a control that I'm using here.
However, as the top two levels in the TreeView do not need bookmarking, the customer wants an Image there. I found this page who's response gets CheckBoxes to disappear on specific Nodes. Unfortunately, the API calls clash with the ones used in the above Tri-State TreeView and they both can't work at the same time.
Basically, what I'm looking for is how to get Images in nodes on the top two levels, and Tri-State CheckBoxes on the lower levels. I'd be more than willing to try another Tri-State CheckBox if necessary.
Also, when the user clicks on the Image in the top two levels, the image shouldn't change. I found this page which does keep the image from changing, but removes the PlusMinus, Lines, and RootLines from the control.
Sorry in advance that this is such a ridiculous and specific request.
Ok, I finally got this figured out. Using the Tri-State Treeview Control, I am able to still have access to the AfterClick event on the Treeview.
I had added a series of Checkbox icons to the ImageList, and after determining which CheckState (of the 3) my underlying object was in. Then I set the ImageIndex, SelectedImageIndex, and StateImageIndex (probably don't need the last one, but I was being thorough) to the proper index of the ImageList.
I won't post any code for now, but if you are trying to do the same thing, let me know and I'll upload until it becomes clear.
