In one of my application I have syncfusion gridcontrol.
After doing a paste operation (CutPaste.Paste()) I would like to clear or reset the gridcontrol clipboard.
Is there any way I could perform this?
Thanks in advance.
Thanks for using Syncfusion products.
In order to clear the contents of the clipboard, use Clipboard.Clear() method in the ClipboardPasted event. This event will trigger after the pasting is done. Please refer to the below code and sample,
// Event Subscription
gridControl1.Model.ClipboardPasted += Model_ClipboardPasted;
// Event Customization
private void Model_ClipboardPasted(object sender,
Syncfusion.Windows.Forms.Grid.GridCutPasteEventArgs e)
{
Clipboard.Clear();
}

The .ToImage() function in GMap.Net does not appear to wait for the map data to be downloaded before the screenshot is taken. This results in images with blank tiles. Is there any existing capability that would allow GMaps to wait until the map is loaded?
I already posted my question on GitHub but haven't gotten a response so far. So any help is appreciated.
VB.NET Code
Private Function TakeBitmapScreenShot() As Image
'''''''''''''''''''''''''''''''''''''''''
'Code to wait until all tiles have loaded
'''''''''''''''''''''''''''''''''''''''''
Return GMapControl.ToImage()
End Function
You can Handle the event (OnTileLoadComplete ) which fires when the tile images completly loaded and then you can take the screenshot
GMapControl1.OnTileLoadComplete += GMapControl1_OnTileLoadComplete;
private void GMapControl1_OnTileLoadComplete(long ElapsedMilliseconds)
{
GMapControl.ToImage();
}
Two of the ways around this are using the TilePrefetcher or even better this code.
using code.org i need to be able to have a user click on a button that takes them to another screen without using OnEvent(s) constantly, can anyone help me out? Newb here. Thank you for your time.
You can create a function with a value for button and string and put a callback inside
function event(button,input_type, screen) {
onEvent(button, input_type, function() {
setScreen(screen);
});
}
Given the following code:
TextBox tb = new TextBox();
tb.addValueChangeHandler(new ValueChangeHandler<String>() {
#Override
public void onValueChange(ValueChangeEvent<String> event) {
Window.alert(event.getValue());
}
});
onValueChange will be called if the TextBox loses focus. I am trying to have it called whenever the input value changes. The solutions I have read all involve handling the keyup and paste events such as in this answer. How to build a Facebook-style input box in GWT Hasn't this been addresses in GWT 2.5.1? Is there a way to bind to the native input change method? Another widget or using the UI framework would be acceptable if they have this functionality
The only way in GWT is to bind to the key down/key up and paste events.
Please send a patch to add support for the input event (using addBitlessDomHandler): http://www.gwtproject.org/makinggwtbetter.html, it should be rather easy (add a acase in DOMImpl) and has good chances to make it in (and if sent early enough, would have good chances to ship in GWT 2.6)
The solution is use the right event and that is the input event, so look how to hook on it, there are many ways to do it. Because I work with elements and not with Widgets this the code that I use it:
Element input = Document.get().getElementById("my-input");
DOM.sinkBitlessEvent(input, "input");
DOM.setEventListener(input, event -> GWT.log("Event!"));
You can just use addChangeHandler() and onChange, tb.getValue().
I used the following to detect when the value of a textbox changes. Just bare in mind this only detects if the text box goes from empty to full or full to empty. This was done to try reduce async calls to the server to validate the input
#UiHandler("notes")
#SuppressWarnings("unused")
public void notes(KeyUpEvent event) {
if (!areNotesCaptured && !notes.getText().isEmpty()){
fireLeaveSelectionUpdatedEvent();
areNotesCaptured = true;
} else if (areNotesCaptured && notes.getText().isEmpty()){
fireLeaveSelectionUpdatedEvent();
areNotesCaptured = false;
}
}
I'm trying to handle the event when the close button of a Window is clicked:
// View Code
#Override
public void attachWindowListener(WindowListener listener) {
window.addWindowListener(listener);
}
// Presenter code
view.attachWindowListener(new WindowListener(){
public void windowHide(WindowEvent we) {
GWT.log("Window Event - Processing fields");
processFields();
}
});
However, the windowHide function seems to be not executed since I can't see the log I placed there.
How to properly handle that event?
How about
Window.addCloseHandler(
new CloseHandler<Window>()
{
public void onClose( CloseEvent<Window> windowCloseEvent )
{
// Do your worst here
}
} );
I usually put this in onModuleLoad() in my EntryPoint class.
Cheers,
Based on the information provided I would guess that either a.) the events you think are firing do not fire for the Window component (even if it seems like they should) or b.) the events are firing but in a different order than you expect.
For example, it's possible that a BrowserEvent or some other event is firing first as the window is being closed and the Window object's WindowEvent never fires. According to the API docs for GXT 2.x, the WindowEvent will fire on hide and deactivate but it does not specify that it fires on close. The GXT 3.0.x API doc is less clear on this point but I would assume the same behavior. Unfortunately Sencha does not provide good documentation on what events fire for a given component and in what order.
With that said, I have had some luck working through similar issues to this by using a debug class which outputs all the events on a component to which it is attached. This may shed some light on which events are firing and their order of execution, and you may find an optimal event to which you can attach your processFields() method.
For a good example of a debugger class, see this answer from a related post: https://stackoverflow.com/a/2891746/460638. It also includes an example of how to attach the debugger to your component.
API Doc for Window, GXT 2.x: http://dev.sencha.com/deploy/gxt-2.2.5/docs/api/com/extjs/gxt/ui/client/widget/Window.html
API Doc for Window, GXT 3.0.x: http://dev.sencha.com/deploy/gxt-3.0.0/javadoc/gxt/com/sencha/gxt/widget/core/client/Window.html
This worked:
window.addListener(Events.Hide, new Listener<ComponentEvent>() {
#Override
public void handleEvent(ComponentEvent be) {
// Do stuff
}
});
in the silverstripe backend I´m managing certain PageTypes via a ModelAdmin. That works fine so far, the only thing i can´t figure out is how to make a Page being "Published" when saving it.
Thats my code:
class ProjectPage extends Page {
public function onAfterWrite() {
$this->doPublish();
parent::onAfterWrite();
}
}
At the moment I can still see the ModelAdmin-created Pages in the Sitetree and I can see they are in Draft Mode. If I use the code above I get this error:
Maximum execution time of 30 seconds exceeded in
.../framework/model/DataList.php
Many thx,
Florian
the reason why you get "Maximum execution time exceeded" is because $this->doPublish(); calls $this->write(); which then calls $this->onAfterWrite();. And there you have your endless loop.
So doing this in onAfterWrite() or write() doesn't really work
you should just display the save & publish button instead of the save button
But I guess its easier said than done.
Well adding a button is actually just a few lines, but we also need a provide the functions that do what the button says it does.
This sounds like the perfect call for creating a new Module that allows proper handling of Pages in model admin. I have done this in SS2.4, and I have a pretty good idea of how to do it in SS3, but no time this week, poke me on the silverstripe irc channel on the weekend, maybe I have time on the weekend.
I found the same need/lack and I built a workaround that seems to work for me, maybe it can be useful.
public function onAfterWrite()
{
if(!$this->isPublished() || $this->getIsModifiedOnStage())
{
$this->publish('Stage', 'Live');
Controller::curr()->redirectBack();
}
parent::onAfterWrite();
}
Create a class that extends ModelAdmin and define an updateEditForm function to add a publish button to the actions in the GridFieldDetailForm component of the GridField.
public function updateEditForm($form) {
if ( ! singleton($this->owner->modelClass)->hasExtension('Versioned') ) return;
$gridField = $form->Fields()->fieldByName($this->owner->modelClass);
$gridField->getConfig()->getComponentByType('GridFieldDetailForm')->setItemEditFormCallback(function ($form) {
$form->Actions()->push(FormAction::create('doPublish', 'Save & Publish'));
});
}
Then create a class that extends GridFieldDetailForm_ItemRequest to provide an action handler for your publish button.
public function doPublish($data, $form) {
$return = $this->owner->doSave($data, $form);
$this->owner->record->publish('Stage', 'Live');
return $return;
}
Make sure the extensions are applied and you're done.
Or, you could just grab all the code you need from GitHub.
