I have an textbox with onChange method and button to make some actions. But if I type some thing in textbox and not clicking any where , click that button, It calls onClick method and then onChange method.Or first onChange and then OnClick but I should disable all actions after that onChange method.
Add the check to your onClick() method. The onChange() for a text box is fired after a certain period of time or after you deselect your component. If you deselect your component by clicking on a button it sounds pretty natural to me to get the onClik first and then the onChange. There is no way of controlling (as far as I know) these events, except on server side.

Keep in mind that you are developing a WEB application and not a Desktop Application. And event if the development of zk applications may look pretty similar to the desktop applications they are not and they have their limitations.
I found solution :
First for Textbox onFocus method I disable next button , and user cant click it.
Second for Textbox onBlure method I enable next button. (To be fired onBlure action user should click somewhere on window or press tab and this fires onChange action)

I have a function that I'm using to grab properties of a widget when a user changes it's input for undo/redo functionality. I have entries connected such that when a user clicks on them (focus-in-event), the current text is taken and stored. However, I've been having a big problem trying to do this with a file chooser or file chooser button. For some reason, when I click the button or chooser, and I have my handler wired to the focus-in-event signal, the filename is not grabbed. I'm not sure how to grab this value before the user changes it. I'm using glade to attach handlers to signals. Thanks!
You can achieve this by calling the get_filename method within a selection-changed callback. The response signal runs when the ok, or cancel button is clicked, and can be used to set or update which file/folder is selected to perform actions on.
I would like to know what is recommended way to focus on component from outside the component. I am trying to focus on a input field when the person closes the modal window.
Typically you would use an action in the modal that triggers when the close button is clicked, and you would send the action up to the component with the input with sendAction. In the component with the input, you could then use Ember.$ or any other method to tell the browser to focus on an element.
The situation is more complex if the modal is not inside the component that contains the input. In that case you might need to use a service or event. But it's much easier to use the first method.
I have a dialog with radio button with groups of 4 buttons.
DDX_Radio(pDX, D_RADIO_GROUPLEAD, intToStore) in DoDataExchange is there for saving and loading.
It works perfectly fine.
Selection changed, DoDataExchange called, stores and loads data no problem.
Problem occurs when I hide one of the radio button (hide it via ShowWindow(SW_HIDE). Let's just call it 3rd button for reference. And previously, the selection was this 3rd button.
I have logic that will automatically select the default one (one with Group flagged as true in the editor). I call the button's SetCheck(1).
Visually everything seems to be working.
However, when I click on 2nd button, then try to call DoDataExchange (hence DDX_Radio), it will causes debug assertion failure. (dlgdata.cpp Line 286)
AND
the data is not properly populated back in intToStore.
Why could this be and how can I avoid this issue?
Thank you.
The problem is, that the auto radio button stuff in Windows skips buttons that are disabled. In detail. You click on button 2 while button 3 is selected and disabled. Button 2 gets selected but button 3 is not unchecked.
The next problem occurs when DoDataExchange runs. It doesn't check if a button is enabled or disabled. DDX_Radio just loops over all radio buttons, and it find 2 buttons in the group are enabled. This causes the ASSERT. DDX_Radio don't care if a button is enabled or disabled.
My advice: Use a custom OnClick handle by yourself, and disable all other buttons manually.
I have an application in which users, upon logging in, are prompted with a modal dialog where they must choose the facility they wish to work out of. At this stage, the application looks like this:
The modal dialog is shown by calling this method:
bool __fastcall ShowFacChoiceForm()
{
TFacChoiceForm *Form = new TFacChoiceForm( Application );
bool Result = ( Form->ShowModal() == mrOk );
delete Form;
return Result;
}
In this case, TFacChoiceForm inherits from TForm so the ShowFacChoiceForm() function is calling the standard TForm.ShowModal method documented here.
The issue I am running into is that if my application loses focus, it cannot become the active window again unless the modal dialog itself is clicked. To better illustrate this, I will present the following scenario:
Lets say its Friday afternoon and I decide to goof off a bit and read some web comics. With my application open, I open up another window on top of it, like so:
Then, out of nowhere my boss comes in for a performance review, and I attempt to refocus my application by clicking somewhere on the main form. For example, at the position of this red X in the next image.
In the above image, I have clicked at the location of the red X. Now, both the form containing the web comic, and my application are inactive. Thus, my application does not come to the front of the screen.
However, if I am able to click somewhere on the modal dialog, like the red X in the following image...
...then my application comes to the front like one would expect.
To solve this, I have looked at using something like SetForegroundWindow from the Windows API, but I have not been able to find a way to trigger the event, since my main form does not fire events while I have a modal dialog open.
My question is, how can I make sure that if the user clicks anywhere on my application that it is brought to the front? Is there a property I can edit in my form to do this?
If you set modalresult to mrcancel in the ondeactivate of the modal dialog then the main form will get focus when its clicked. You can then check if the user is logged in the mousedown event of the main form and if not, show the modal dialog again.
I have a legacy C++ MFC application with a complex GUI with Ribbons. I have a use case as follows : User clicks button A on a ribbon panel and does some work. After his work is done, before he can exercise the rest of the GUI controls, he absolutely must click button B on the same ribbon panel, and failing to click button B in this manner results in a crash if the user exercises some other controls.
Hence, in order to deal with this use case, I figured it would solve my problem if I could disable all of program's GUI controls in Button A's event handler except button B. Button B's event handler then enables the rest of the GUI controls. This way, I ensure that button B always gets pressed after button A.
Hence, my question to you is as follows : Is there a way to disable all GUI controls in one fell swoop, and then enable and disable controls individually?
I know how to enable or disable controls individually, but I have not yet come across an API that allows one to disable all controls.
This way, you get all IDs of the ribbon buttons:
CList<UINT, UINT>& lstItems;
CMFCRibbonBar *pRibbon = ((CMDIFrameWndEx*) AfxGetMainWnd())->GetRibbonBar();
pRibbon->GetItemIDsList(lstItems);
Put the three lines in your view's OnInitialUpdate() handler.
Then use the list to compare the IDs coming through your OnCmdMsg() handler to disable all the buttons (except button B).
