how can i get the action (what button was clicked) when a button is clicked in the pager?(edit, del, add...)
You probably means button of the navigation bar or navigator (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:navigator).
You can implement what you want with at least three different ways:
You define your custom buttons which look like the original add/edit/del buttons (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:custom_buttons) and use {add:false, edit: false, del: off} parameter of navGrid to switch off standard buttons.
You can use addfunc, editfunc and delfunc if you want replace the default add/edit/del functions.
You can use onclickSubmit or afterSubmit or some another supported events (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:form_editing#events) of add/edit/del button to do some additional action on click the buttont or on submit.
You can chose the way which is the best for your requirements.
You can use the grid onPaging event:
This event fires after click on [page
button] and before populating the
data. Also works when the user enters
a new page number in the page input
box (and presses [Enter]) and when the
number of requested records is changed
via the select box. To this event we
pass only one parameter pgButton
(string) which can be -
first,last,prev,next in case of button
click, records in case when a number
of requested rows is changed and user
when the user change the number of the
requested page.requested page.
Also there are beforeRequest and LoadComplete events. Examples that worked for me are as follows:
beforeRequest: function () {
$.blockUI();
//alert("before request");
},
loadComplete: function () {
//alert("load complete");
$.unblockUI();
}

Suppose there are several buttons created programmatically, and there is a common button handler.
onButtonClicked(){
// print button attribute
}
How to understand inside the handler which button is pressed?
WITHOUT passing something special inside the function call. That won't do:
onButtonClicked("button" + i);
In JavaScript, for example, inside the handler, there is $(this), which immediately "understands" which button is pressed.
Maybe there is a similar mechanism in Flutter? I want to hang attributes on the button (without knowing which ones in advance), and then have access to them in the handler.
I think there is only one way to write the print('your function name') inside your function
Just pass the Parameter inside your method.
for example:-
onButtonClicked(Parameter){
// print button attribute
print("${parameter}");
}
And pass different parameter for different buttons.
I have two radio buttons in my interface. I also have some pushbuttons. When ever I click a pushbutton I want it to call a function according to the selected radio button.
I tried adding the function given below
function rotation_SelectionChangeFcn(hObject, eventdata, handles)]
Tag = get(hObject, 'Tag');
disp(Tag);
But nothing is coming up when I change the selection. I want to know whether there is any mistake in the way I implemented the code or is there a better way of doing this?
Whenever you use radiobuttons you might want to regroup them in button groups, then it's quite easy to play with radio buttons, and you make sure that only 1 radio button per group gets selected at any time.
For radio buttons in button groups, you want to use the following:
get(eventdata.NewValue,'Tag')
to get the tag of the new value just being selected. You can also use OldValue as well if you want.
In the callback of your pushbutton, you can query whether a radio button is activated with its 'value', i.e. 1 if it is selected.
StateRadioButton = get(handles.RadioButton1,'Value'); %assuming the tag is "RadioButton1".
The hObject property is particular for the specific callback in which it is used, otherwise you need to use the handles structure to access elements from other functions.
I have a dataPointGrid and I want to check if a record from it is being selected (mouse clicked on)
Data point grid above. I want to check if a folder (record) is being selected.
Is there a method that does this?
Add ListGrid#addSelectionChangedHandler() on list grid that is called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).
Look at the ListGrid#setSelectionType() as well that defines a listGrid's clickable-selection behavior (MULTIPLE, SINGLE, SIMPLE or NONE)
is it possible in TinyMCE to know which button was clicked? so I could place specific action on specific event of a specific button.
the buttons here are default control-buttons like bold/italic/select-font not a custom button one.
probably in the init, but I have no idea what to call. I could capture the editor's events but not the button's.
For example, let's say I want a messagebox popped-up everytime bold button is clicked. How to capture the click event of bold button? is creating custom button the only way?
No, you can define an own command and call this command (+ the defualt action) on buttonklick. I do not know if you want a generic way for all buttons. But it is easy to do it just for one or two buttons.
Example: We want to put an action on the bold button.
First we define an own command in one of our own plugins (in the "init : function(ed, url)" -section):
ed.addCommand('my_bold', this.my_bold, this); //calls the function my_bold
Then we overwrite the default action with an the command:
if (ed.controlManager.get('bold')){
ed.controlManager.get('bold').settings.cmd='my_bold_action';
};
Now, we only need to define the function my bold
my_bold: function() {
// exectution of regular command
this.editor.execCommand('Bold');
// now do whatever you like here
...
},
ed.controlManager must be called in "onInit" methode :
ed.onInit.add(function(editor) {
.......
........
if (editor.controlManager.get('bold')){
editor.controlManager.get('bold').settings.cmd='my_bold_action';
};
});
I have a situation here: I have a form field with trigger xtype, what I want to happen on my trigger function is to open a window with a list or grid of data in it. I want to get the value of those data and assign it as the value of my form field with trigger. Can anyone help me solve this problem. Thank you very much.
You have multiple solutions for this.
You can make use Saki's simple message bus to do the communication between extjs components.
You can create an custom event for your trigger field. When user selects a record in your window, fire the event with the selected record.
Inside your onTriggerClick :
Display your window with grid / view for user selection
Inside your Window (on some submit button):
onSubmitClick: function(){
// Get the selected record & fire event
var selected = grid.getSelectionModel().getSelected();
triggerFieldObject.fireEvent('recordSelect',selected);
}
Inside your event processing (Will be on TriggerField):
onRecordSelect: function(record) {
// Now you have access to the selected record.. process it,
// Set the trigger field value etc
this.setValue('Your Value for Trigger Field');
}
Note: This is a skeleton code and not a complete solution. You will need to add your code according to your requirements.
