I made vertical listview that contains horizontal listview in each row and I want to implement the event that when I clicked one item, I can add new item at the end of the row.
For that I try to manage the item by ArrayList> and I added setOnItemClickListener in the getView method of vertical adapter. and It doesn't work! Actually It rarely works... (when I clicked about 20 times, It works once.)
I tried unclickable and unfocusable properties in xml layout but doesn't work.
please hlp me... Here is my code
in MainActivity
I used VerticalAdapter like this. I set totallist as the parameter of VerticalAdpater
verListAdapter = new VerticalAdapter(getActivity(), R.layout.schedule_routine, TotalList);
listview.setAdapter(verListAdapter);
public View getView(int position, View convertView, ViewGroup parent) {
View rowView;
this.aposition = position;
rowView = LayoutInflater.from(getContext()).inflate(R.layout.part_list_item, null);
hListView = (HorizontialListView) rowView.findViewById(R.id.hlistview);
tv_info = (TextView) rowView.findViewById(R.id.tv_infoitem);
tv_info.setText(Integer.toString(position));
hListView.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int iposition, long id) {
tv_info.setText("hello");
PartContent temp_part = new PartContent("part", R.drawable.plus);
PartContent temp_base_part = new PartContent("part", R.drawable.dumb);
if(iposition == (totallist.get(aposition).size()) - 1) {
tv_info.setText(Integer.toString(iposition));
totallist.get(aposition).set(iposition, temp_base_part);
totallist.get(aposition).add(temp_part);
}
HorizontialAdapter hortempAdapter = new HorizontialAdapter(getContext(), R.layout.part_item, getItem(iposition));
hListView.setAdapter(hortempAdapter);
hortempAdapter.notifyDataSetChanged();
}});
HorizontialAdapter horListAdapter = new HorizontialAdapter(getContext(), R.layout.part_item, totallist.get(position));
hListView.setAdapter(horListAdapter);
return rowView;
}

When I run my code scroll bars coming as disabled. I want to enabled it with fixed size. I am referring to this example and I have added ScrolledCompisite code in the creatContenyArea method. Appreciate suggestion on how to fix this thanks.
#Override
protected Composite createContentArea(Composite parent) {
ScrolledComposite sc = new ScrolledComposite(parent, SWT.H_SCROLL
| SWT.V_SCROLL);
sc.setMinSize(100, 100);
sc.setExpandHorizontal(true);
sc.setExpandVertical(true);
sc.setBackground(parent.getDisplay().getSystemColor(SWT.COLOR_INFO_BACKGROUND));
sc.setAlwaysShowScrollBars(true);
Composite comp = super.createContentArea(sc);
comp.setBackground(parent.getDisplay().getSystemColor(SWT.COLOR_INFO_BACKGROUND));
FillLayout layout = new FillLayout();
layout.marginWidth=5;
parent.getShell().setLayout(layout);
Link l = new Link(comp,SWT.NONE);
l.setText(
"This a custom tooltip you can: \n- pop up any control you want\n- define delays\n - ... \nGo and get Eclipse from <a>http://www.eclipse.org</a>");
l.setBackground(parent.getDisplay().getSystemColor(SWT.COLOR_INFO_BACKGROUND));
l.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
openURL();
}
});
sc.setContent(comp);
return comp;
}
I want to control the TabPane and switch tabs with a Canvas, basically hide the tab headers and use canvas instead, the canvas displays different "Devices" and when user click on the device, the TabPane switch to show the content of that device.
fun canvasFlow_Click(mouseEvent: MouseEvent) {
val d = flowPresenter.click(mouseEvent)
if (d != null) {
flowPresenter.select(d)
logger.info("switch to ${d.position}")
tab.selectionModel.clearSelection()
tab.selectionModel.select(d.position)
}
}
Why select doesn't work? I don't see tab content changed. from log, I see "switch to 1", "switch to 2" correctly, just the tab doesn't switch! Why?
Note: this is plain javafx and might not be the exact solution in your case (hard to tell without example) - but actually I can reproduce the described behavior.
The problem seems to be calling clearSelection: TabPane with tabs should have exactly one selected tab - which is not specified. But every internal collaborator (skin, header, listener) goes to great lengths to guarantee that constraint - this assumption was wrong, in fact the skin gets confused if the selection changes to empty - the previously selected content is not removed. Might be a bug, either don't allow the selectionModel to be empty or improve the skin to cope with it (wondering how that would be supposed to look - hide the content?)
Anyway, here the solution is to not call that method before manually selecting a tab. There's no need to do so anyway, it's a SingleSelectionModel so takes care of allowing at most one item selected.
An example: un/comment the clearSelection and see how the content is not/ correctly updated with/out the call.
public class TabPaneSelection extends Application {
private Parent createContent() {
TabPane pane = new TabPane();
HBox headers = new HBox();
for (int i = 0; i < 3; i++) {
int index = i;
Tab tab = new Tab("header " + i, new Label("content " + i));
pane.getTabs().add(tab);
Button button = new Button(tab.getText());
button.setOnAction(e -> {
// do __not__ clear selection
//pane.getSelectionModel().clearSelection();
pane.getSelectionModel().select(index);
});
headers.getChildren().add(button);
}
BorderPane content = new BorderPane(pane);
content.setTop(headers);
return content;
}
#Override
public void start(Stage stage) throws Exception {
stage.setScene(new Scene(createContent(), 400, 300));
//stage.setTitle(FXUtils.fxVersion());
stage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I'm developing an app that uses drag & drop operations. The drag & drop part includes four containers as drop targets and two draggable labels.
The app works as expected in the simulator, but when I install it on my Android phone, the background of the dialog (otherwise white) turns black for a swift moment as soon as the draggable components (labels) are released (then gets back to the original light color).
In the theme builder, I have set the background of the dialog to an almost white color (unselected, selected, pressed, disabled), but that doesn't show any effect.
Is there any turnaround to keep the background color stable? Any help would be appreciated.
Here is the relevant code excerpt:
Dialog dialog_W1 = new Dialog();
dialog_W1.setScrollableY(true);
dialog_W1.setLayout(new BoxLayout(2));
dialog_W1.setScrollableY(true);
dialog_W1.setTitle("Acerte o bichinho");
Image img_Cat = Image.createImage("/cat.png");
ScaleImageLabel label_Scaled_Image = new ScaleImageLabel(img_Cat);
label_Scaled_Image.setBackgroundType(Style.BACKGROUND_IMAGE_SCALED_FIT);
label_Scaled_Image.setUIID("NewLabel");
Label label_1 = new Label("ga");
Label label_2 = new Label("to");
label_1.setUIID("LabelWord");
label_2.setUIID("LabelWord");
label_1.setDraggable(true);
label_2.setDraggable(true);
Container c_1 = new Container();
Container c_2 = new Container();
Container c_3 = new Container();
Container c_4 = new Container();
c_1.setDropTarget(true);
c_2.setDropTarget(true);
c_3.setDropTarget(true);
c_4.setDropTarget(true);
c_1.setLayout(new BoxLayout(2));
c_2.setLayout(new BoxLayout(2));
c_3.setLayout(new BoxLayout(2));
c_4.setLayout(new BoxLayout(2));
c_1.setUIID("Container_1");
c_2.setUIID("Container_1");
c_3.setUIID("Container_2");
c_4.setUIID("Container_2");
c_3.add(label_2);
c_4.add(label_1);
GridLayout gl = new GridLayout(2,2);
Container container_0 = new Container(gl);
container_0.add(c_1);
container_0.add(c_2);
container_0.add(c_3);
container_0.add(c_4);
ArrayList <Container> list_Containers = new ArrayList<>();
list_Containers.add(c_1);
list_Containers.add(c_2);
list_Containers.add(c_3);
list_Containers.add(c_4);
ArrayList <Label> list_Labels = new ArrayList<>();
list_Labels.add(label_1);
list_Labels.add(label_2);
for (Label label : list_Labels) {
label.addDragOverListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
for (Container c : list_Containers) {
int int_C = c.getComponentCount();
if (int_C == 1) {
c.setDropTarget(false);
} else if (int_C == 0) {
c.setDropTarget(true);
}
}
}
});
}
I suggest showing the Dialog as a modless dialog instead of using the show method use showModless() or similar.
Odd things like this can happen because of the EDT nesting inherent in modal dialogs, normally we don't recommend using dialog for anything more than simple notifications. When we use drag and drop from a dialog like component we use InteractionDialog.
I'm trying to create new GTK Notebook tabs that contain both a name (as a Label) and a close button (as a Button with an Image) with the following code:
Label headerLabel = new Label();
headerLabel.Text = "Header";
HBox headerBox = new HBox();
Button closeBtn = new Button();
Image closeImg = new Image(Stock.Close, IconSize.Menu);
closeBtn.Image = closeImg;
closeBtn.Relief = ReliefStyle.None;
headerBox.Add(headerLabel);
headerBox.Add(closeBtn);
headerBox.ShowAll();
MyNotebook.AppendPage(childWidget, headerBox);
This seems to work just fine; however, the button is about 1.5 - 2 times the size is needs to be, so there is a lot of extra space around the image inside the button. Having looked at remove inner border on gtk.Button I now see that the culprit is the "inner-border" style property of the GtkButton, but (being new to GTK) I can't seem to figure out how to override its value.
Is there some method of doing this that I'm missing? I don't have any reservations about not using a Button/Image combination, so any more obvious suggestions are welcome.
Note: I have seen the suggestion in the linked question to use an EventBox, but I was not able to add the Relief and mouseover effects to that Widget.
You are in luck. I just made the exact same thing yesterday, and can fortunately give you some code. The trick is to create a Custom Tab Widget.
public class MultiTab : Gtk.Box
{
public Gtk.Label Caption;
Gtk.Image img = new Gtk.Image(Platform.IMG + "tab_close.ico");
public Gtk.ToolButton Close;
public Gtk.Notebook _parent;
public MultiTab ( string name )
{
CreateUI(name);
}
public MultiTab(string name, Gtk.Notebook parent)
{
_parent = parent;
CreateUI(name);
CreateHandlers();
}
void CreateUI(string name)
{
Caption = new Gtk.Label(name);
Close = new Gtk.ToolButton(img,"");
PackStart( Caption );
PackStart( Close );
ShowAll();
Close.Hide();
}
void CreateHandlers()
{
Close.Clicked += delegate {
_parent.RemovePage(_parent.CurrentPage);
};
}
public bool Active;
}
Next all you have to do is use this widget(or a similar one created by you) in Gtk.Notebook like this:
MyNoteBook.AppendPage(new <YourPage>(), new MultiTab("<your caption>",this));
And You're done.
Here is a screenshot:
Add this:
RcStyle rcStyle = new RcStyle ();
rcStyle.Xthickness = 0;
rcStyle.Ythickness = 0;
closeBtn.ModifyStyle (rcStyle);
Add items to box using Gtk.Box.PackStart/PackEnd methods rather than generic Gtk.Container.Add method. PackStart/PackEnd will allow you control how child widgets will be allocated space:
headerBox.PackStart (headerLabel, true, true, 0);
headerBox.PackEnd (closeBtn, false, false, 0);
In my editor, I have a composite containing a label control right at the top which flashes informative message in red colour whenever the user enters erroneous inputs in any of the below lying fields. The text keeps changing dynamically depending on user's input. I am able to achieve the effect of displaying red coloured text on erroneous inputs and displaying nothing in the label for correct inputs.
But, I want that when there is no error to display in the label composite, the rest of the below fields shift up in display. And when there is error to display, the error should appear in it's place(at the top of all other fields) pushing the other fields down.
Is there a way to achieve this effect without redrawing all the controls again?
Yes, call layout (true) on the parent.
For example I have a view that has a search bar at the top who's visibility can be toggled. I have a method to create the search composite and one to remove it:
private void createNameSearchBar () {
mySearchControl = new CardSearchControl (myViewComposite, SWT.NONE);
mySearchControl.setSearchListener (this);
}
private void disposeNameSearchBar () {
mySearchControl.dispose ();
mySearchControl = null;
}
private CardSearchControl mySearchControl = null;
private Composite myViewComposite;
private boolean mySearchBarState;
To hide or show the search bar control I call this method (myViewComposite is the top level control that owns the search bar and all the other contorls):
public void setSearchBarState (boolean show) {
mySearchBarState = show;
if (myViewComposite == null || myViewComposite.isDisposed ())
return; // no work to do
if (mySearchBarState && mySearchControl == null) {
createNameSearchBar ();
mySearchControl.moveAbove (null);
myViewComposite.layout (true);
} else if (!mySearchBarState && mySearchControl != null) {
disposeNameSearchBar ();
myViewComposite.layout (true);
}
}
