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 want a button from the command line bar to be visible or invisible depending on whether a record has been selected in the lookup field from the main form or not.
If no record has been selected, then the button should be displayed. Otherwise not.
For this problem, I want to use the Power Fx in PowerApps, but I haven't found a command yet, which shows me the content or something like that of the lookup field. Other field data types like text have worked without problems.
With Javascript, I already managed it without problems, but I would like to do it also in PowerFx if that should work.

The records come from the Table Company, where the attribute is Companyname.
Commands where I think they might work:
If([Selected Record];true;false);If(IsBlank([Selected Record]);true;false);If(IsBlankOrError([Selected Record]);true;false);If(IsEmpty([Selected Record]);true;false)
I guess there are 2 scenarios:
The Lookup form control element is a Dropdown with a Selected output property. Then your approach would work like If(IsBlankOrError(DataCardValue1.Selected),true,false)
If your form control element is a ComboBox then you could use If(CountRows(DataCardValue1.SelectedItems)>0,true,false) or the above described IsBlankOrError.
I have read about using VBA to concatenate terms together using VbCrLf; I personally used Ctrl-Enter to create a second line in the caption field in the properties box.
But, after I do my ctrl-enter, it then only shows the first line of my multi-line caption in the datasheet view of my form.
becomes this...
This form is meant to recreate the functionality our owner is looking for from a current excel spreadsheet (the ability to sort on various columns), so I can't just use a report.
Please tell me I'm missing something obvious such as a caption height property value or something. The multiline caption will be very useful to help maintain appropriate column widths for the data.
Whilst you can display multiple lines of content within the datasheet view for a table by increasing the row height of each record, e.g.:
A more appropriate solution might be to use a text box on a form to display the data, where the height of the text box can be predefined in the design of the form, and scroll bars can be displayed:
There is no solution to adjusting column headers in the specific "datasheet" form that I was trying to use. It's a nice quick way that works for 95% of your uses. But, if you need more control (like me and others on the internet) the only solution is to create the form as a "Tabular" form in the form wizard. There are other descriptions of this type of form in Access (just to be confusing).
This is also described as a continuous form likely because that's the form property value toggle when you dive into the details.
It's more work but you have full control over the size, format, etc. of your column headers when creating/designing a tabular form.
I have several ag grids I'm working with that are setup as Master/Detail. I have an external filter setup on the master and that works fine I can extend it to the detail grid but running into a couple issues:
The filter appears to only apply to expanded nodes. Closing and reopening resets the data, though the filter may still have a value.
I haven't figured out a way for the filter to ignore the master if the filter matches detail but not the master.
How I expand the master where the detail matches. I think I will need to use a a timeout so that the grid isn't expanding and collapsing on each key press, but I don't know how to know which grid has matching data.
The code below is what I have so far for just handling the detail grid but this appears to be very slow (plunker: https://next.plnkr.co/edit/S1PNvugCbjPh55jI).
onFilterTextBoxChanged() {
// this.gridApi.setQuickFilter(document.getElementById('filter-text-box').value);
this.gridApi.forEachNode(function(node) {
console.log('node.detailNode', node)
node.gridApi.forEachDetailGridInfo(function(detailGridApi){
console.log('detailGridApi', detailGridApi);
detailGridApi.api.setQuickFilter(document.getElementById('filter-text-box').value);
})
});
}
Just a suggestion, on each keypress event happening on the filter box ->
1) Before calling quickFilter function, Expand all the detail grid using grid event expandOrCollapse because it somehow does the filtering while its in expanded state.
2) Collapse the grid when search filter box is empty and have cross mark to empty it.
Please ignore if it does not suits ur needs. Thanks!
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.
In my (programmatic) Matlab GUI, I have a listbox uicontrol.
What I want is to display checkboxes in front of each option. When a user clicks the checkbox, it's marked (and the element will be considered during the calculations later). While if the user clicks the label, a description of the selected option will be displayed in a text uicontrol to inform the user what the option means.
Basically, I want functionality similar to installation programs where you can select components to install and can get information about said components by clicking them (which does not necessarily mark them as selected).
Is there a way to do this with checkboxes or something similar?
There are actually 2 built-in controls that you could use within Matlab:
com.jidesoft.swing.CheckboxList
com.mathworks.mwswing.checkboxlist.CheckBoxList
Usage example (more details in my Matlab-Java book):
jList = java.util.ArrayList; % any java.util.List will be ok
jList.add(0,'First');
jList.add(1,'Second');
jList.add(2,'Third');
jList.add(3,'and last');
jCBList = com.mathworks.mwswing.checkboxlist.CheckBoxList(jList);
jScrollPane = com.mathworks.mwswing.MJScrollPane(jCBList);
[jhCBList,hContainer] = javacomponent(jScrollPane,[10,10,80,65],gcf);
set(jCBList, 'ValueChangedCallback', #myMatlabCallbackFcn);
jCBModel = jCBList.getCheckModel;
jCBModel.checkAll;
jCBModel.uncheckIndex(1);
jCBModel.uncheckIndex(3);
There's no "ready" way for doing that - as listboxes take only plain strings as entries.
You could "manually" draw checkbox fitted into the area of the listbox, but that might mean quite a lot of work to get everything working...
Another alternative is to go for a java-componenent - e.g. using the jide components available in matlab. See e.g.
http://undocumentedmatlab.com/blog/using-jide-combo-boxes/
for a few examples.
