I have built a bokeh app that allows users to select windows in data and run python code to find and label (with markers) extreme values within these limits. For ease of interaction, I use the box select tool for the range selection. My problem arises when repeating this process for subsequent cases. After markers are placed for the results, they are rendered invisible by setting alpha to zero and another case needs to be chosen. When the new select box includes previous markers, they become visible based on the selection. How do I override this default behavior? Can markers be made unselectable? or can I add code to the customJS to hide them after they are selected?
Thanks in advance for any help!
There are a few possible approaches. If you just want non-selected glyphs to "disappear" visually, you can set a policy to do that as described here:
http://docs.bokeh.org/en/latest/docs/user_guide/styling.html#selected-and-unselected-glyphs
Basically, for bokeh.plotting, pass
nonselection_fill_alpha=0.0,
nonselection_line_alpha=0.0,
as arguments to your plot.circle call or whatever. Or if you are using the low level bokeh.models interface, something like:
renderer.nonselection_glyph = Circle(fill_alpha=0.0, line_alpha=0.0)
But be aware (I think you already are) that the invisible markers are still there, and still selectable if the user happens to draw a box over them with the selection tool.
If you truly want only a subset of the data to be visible and selectable after a selection, I'd say you want to replace the data in the column data source wholesale with the subset in your selection callback.
I have a subform bugging me. The mainform contains buttons etc. Everytime the user close/open the form, the columns width is reset to whatever the table likes. If i open the table directly, the size is as i want. If i change it in the subform, it is not saved. (See screendump)
I would like "Phase" to stay about 2 cm width. I can enter the subform and edit the "Width" but that is only applied to the other views.
I hope you can help, Emil.
I realize this post is almost 2 years old, but I ran into the same problem and came across this post.
I am running MS Access 2013 on Windows 7 Ultimate. I did not find the solutions offered here to work for me, so, I set out to find something that would work for me before I went to VBA code. (Incidentally, I appreciate the link offered by #Patrick_Honorez in his comment on the original post because that was going to be my fall-back solution.)
Anyway, here is what worked for me and I hope perhaps it will work for others as well:
Open the parent form.
In the subform, right-click the column header
for the column for which you wish to adjust the width.
Select the “Field Width” item from the context menu.
In the “Column Width” dialog that appears in step 3, enter the desired column width in points, or, use the [Best Fit] button. Then click the [OK] button to close the dialog and return to the form.
Right-click the parent form’s border to bring up the parent form’s context menu. Click the “Save” item in the context menu.
Now close the parent form.
The next time the form is loaded, the column widths should be as set it step 4 above--at least they are for my setup.
I see this post is quite old and OP must have figured someway to tackle the issue. I came across same issue today and found solution on this link.
For anybody else having same issue, use following code (I modified the code a little because original code from the above mentioned post saves column width of only text boxes but my form has combo boxes too, column width of which was not getting saved) in close and open events of your subform and then open main form in Form View and then manually select desired widths either by mouse, by entering column width value or using best fit. Save the form and reopen to check results. That's it.
Private Sub Form_Close()
Dim ctrl As Control
For Each ctrl In Me.Controls
If (ctrl.ControlType = acTextBox Or ctrl.ControlType = acComboBox) Then
SaveSetting "propertiesDBS", Me.Name, ctrl.Name, ctrl.ColumnWidth
End If
Next
End Sub
Private Sub Form_Open(Cancel As Integer)
Dim ctrl As Control
Dim frm As Form
Dim w As Long
For Each ctrl In Me.Controls
If (ctrl.ControlType = acTextBox Or ctrl.ControlType = acComboBox) Then
w = GetSetting("propertiesDBS", Me.Name, ctrl.Name, 0)
If w <> 0 Then ctrl.ColumnWidth = w
End If
Next
End Sub
I know this is late to the party and most likely going to be the last comment anyone reads, but this can be done quite simply in MS Access 2016 - by someone like myself who has no more than 4 days experience in databasing overall and no experience with writing custom Macro's or VB Script (using only what is native to MS Access).
Here's how I did it.
Scenario - Split Form (Form + Datasheet).
Extra Recommendations:
It pays to be across all properties of every object type in your database, as a change in a field property can cause unpredictable erratic effects, which take ages to figure out why it happened and how to stop it from happening again, whilst delivering your desired outcome.
Me.Requery in your VBA script after every necessary event and also in your main form (generally the 'After Update' event is used most), and be wary that too many Me.Requery's (in unnecessary events) can also be detrimental - so too much of a good thing can be a bad thing.
Bottom Line Up Front - Modify the format of your query that is to be exported/printed.
In 'Design View' of the query you are concerned with, ensure that the fields are in the order you need them outputted in first as this is exactly how the macro will present them for export/print (example could be "Australia" then "Northern Territory" then "Town's In The Northern Half Of The State" then "Darwin" then "Suburbs In The Northern Half Of City").
Switch to 'DataSheet View' in the same query and use the top left folded over triangle looking thingy to highlight the entire data set then right click that same triangle to present an options menu. Select 'Row Height' and type in "15" (default row height in Excel).
Deselect the entire spreadsheet and this time select every column (left click the left most column, hold shift button, scroll over to the right to the far end of the data set and click the last column) and then right click one of the highlighted columns to present another menu. Select 'Field Width' and within that new pop-up menu select 'Best Fit' and then 'OK'.
(Optional - not sure if this helps or hinders but I did it for my purpose) With the columns still selected right click one of the highlighted columns again and select 'Freeze Fields'.
My scenario had buttons with macros configured to run filtered reports so I was able to check this by simply clicking any of those buttons and seeing the report formatting, which it held true to the work I had just done. I exported using another button with a macro that exports to Excel with 'Print Formatting' selected (my main form also had the datasheet view as the only thing that could be printed and was also set in 'Print' formatting.
The Excel spreadsheet opened with all row heights and column widths in a way that I could read every field/record with perfect ease and without extra modification.
This also worked for cascaded combo boxes, with the export only outputting the 'drilled down/filtered' datasheet records, in a format that required no further modifications.
Hope this helps someone, as its saved my hide! :)
Open the Main form in Design. Go to the SubForm. Click on the square at the top left of the SubForm and select 'Properties'. Right-Click the control 'Phase' and click 'Properties'.Click the 'Format' tab and select 'Width'. What do you see there? That should control the widht of control 'Phase' unless you have some overriding coding elsewhere. Input the size you want and see what happens.
Use continuous forms instead. It gives you complete control over how your subform displays.
If you open your subform directly, your property sheet menu should display automatically if the default view is "Datasheet." Click on "All" and change the "Auto Resize" property to "No." This should solve the issue and avoid the need for VBA.
This only works when you open the subform separately. So if you want the changes to be reflected within your main form, you'll have to close it and switch back and forth.
Super annoying by default.
It seems to work as one would expect of you set the view mode to layout view. Drag column widths as needed and save. Go back to form view and it works. It's really dumb it doesn't work the same way in form view our design view.
In Access 365, open main form, right-click sub-form datasheet columns that need width adjustment, use the Field Width to adjust, click on border of main form to select Layout view, and save changes.
Open subform in datasheet view (by double click on subform in the left pannel)
Resize columns as you want by dragging or by right-click the column header for the column for which you wish to adjust the width and select the “Field Width” item from the context menu.
Right-click the subform border to bring up the context menu. Click the “Save” item in the context menu.
Either open the Main Form in Layout View or directly open your Subform in Datasheet View. Right Click on the Field Header, select Field Width, and enter the desired width. Save. Bewm.
My solution (Access 2016) was to create the main & subform, recreate the subform on its own using form wizard and set it up the way I want it, rename the original subform to something else, and finally rename the recreated subform to the original form name. Open the main form and the subform should be laid out the way you want it. You can then delete the original subform you renamed.
I am using GWT 2.4's new DataGrid in a project. I configured the DataGrid with a pagesize of 50.
The available screen is not big enough to display all items and thus a vertical scrollbar is shown (this is actually the main purpose for using a DataGrid in the first place).
I attached a SingleSelectionModel to the DataGrid in order to be able to select items.
This works fine so far.
However I also have another widget with which the user can interact. Based on that user action a item from the DataGrid should be selected.
Sometimes the selected item is not in the visible screen region and the user has to scroll down in the DataGrid to see it.
Is there any way to automatically or manually scroll down, so that the selected item is visible?
I checked the JavaDocs of the DataGrid and found no appropriate method or function for doing that.
Don't know if this works, but you could try to get the row element for the selection and use the scrollIntoView Method.
Example Code:
dataGrid.getRowElement(INDEX_OF_SELECTED_ITEM).scrollIntoView();
The answer above works pretty well, though if the grid is wider than your window and has a horizontal scroll bar, it also scrolls all the way to the right which is pretty annoying. I was able to get it to scroll down and stay scrolled left by getting the first cell in the selected row and then having it scroll that into view.
dataGrid.getRowElement(dataGrid.getVisibleItems().indexOf(object)).getCells().getItem(0).scrollIntoView();
Don't have time to try it out, but DataGrid implements the interface HasRows, and HasRows has, among other things, a method called setVisibleRange. You just need to figure out the row number of the item that you want to focus on, and then set the visible range from that number n to n+50. That way the DataGrid will reset to put that item at the top (or near the top if it is in the last 50 elements of the list backing the DataGrid). Don't forget to redraw your DataGrid.
Have you already looked at this? If so, I'd be surprised that it didn't work.
Oh, and since this is one widget talking to another, you probably have some messaging set up and some message handlers so that when the user interacts with that second widget and "selects" the item, the message fires on the EventBus and a handler for that message fixes up the DataGrid along the lines I've described. I think you'll have to do this wiring yourself.
My solution, a little better:
dataGrid.getRow(model).scrollIntoView();
I got a Out of bounds exception doing the above.
I solved it getting the ScrollPanel in the DataGrid and used .scrollToTop() and so on on the ScrollPanel. However, to access the ScrollPanel in the DataGrid I had to use this comment:
http://code.google.com/p/google-web-toolkit/issues/detail?id=6865
As Kem pointed out, it's annoying the "scrollToRight" effect after the scrollIntoView. After me, Kem's solution gives a better behaviour than the base one as usually the first columns in a table are the more meaningful.
I improved a bit his approach, which scrolls horizontally to the first column of the row we want to be visible, by calculating the first visible column on the left before applying the scroll and then scrolling to it.
A final note: Columns absolute left is tested against "51". This is a value I found "experimentally" by looking the JS values in the browser's developer tool, I think it depends on the table's style, you may need to change/calculate it.
Below the code:
public void scrollIntoView(T next) {
int index = datagrid.getVisibleItems().indexOf(next);
NodeList<TableCellElement> cells = datagrid.getRowElement(index).getCells();
int firstVisibleIndex = -1;
for(int i=0; i<cells.getLength() && firstVisibleIndex<0;i++)
if(UIObject.isVisible(cells.getItem(i)) && (cells.getItem(i).getAbsoluteLeft() > 51) && (cells.getItem(i).getAbsoluteTop() > 0))
firstVisibleIndex = i;
cells.getItem(firstVisibleIndex>=0? firstVisibleIndex : 0).scrollIntoView();
}
I am working on a new project and I am using Joomla version 1.5.22.
I need to display one horizontal search form in the middle of home page and the same search form in vertical style in all other pages but in left position.
So what I did is, I created two template files one for horizontal search(horizontal.php) and other for vertical search (vertical.php) and in mod_modulename.php I tried to load the respective modules based on a certain condition and changed the position left or middle according to it. The positions are changed in the database to get effected in the admin panel.
if(condition) {
modModulenameHelper::changeToVertical($position);//to change position in database to left
require( JModuleHelper::getLayoutPath( 'mod_modulename', 'vertical'));
}
else {
modModulenameHelper::changeToHorizontal($position);//to change position in database to middle
require( JModuleHelper::getLayoutPath( 'mod_modulename', 'horizontal'));
But I am not getting the correct output. It is loading the respective modules based on the condition. But the position is not assigned at first. And if I press Ctrl+F5 or refreshes, the page will be loaded with the desired output.
Why is this happening? Any Solution??
The problem is that you are changing the position after the fact. By the time you are changing the position, Joomla has already assigned the module to a position. It's an order of operations thing.
Instead, why not just use 2 instances of the module? Rather than going through this trouble, simply add a parameter to the module that allows you to select horizontal or vertical, then assign one to the home page menu item and another to the rest of the pages. This would also allow for putting the module in other positions instead of hard coding it in to the module.
I am using the ScrolledComposite for a existing control(with many children) based on the method2 mentioned here :http://www.placelab.org/toolkit/doc/javadoc/org/placelab/util/swt/SwtScrolledComposite.html
The only change is instead of creating a new shell & display I am using the existing control's parent.
I am seeing the scroll bars as expected but the existing control/content is displayed form the centre & not from the start. The first half(vertically split) of the layout is empty & the actual control/content gets displayed in the right-half.
I checked bounds, Origin, size etc. they seem to be fine.

Any clues
Thanks in advance
Did you delete the Composite c1? maybe that is in the left side.
You could also provide what is exactly your change to the code.
