I have a major problem with my qt6 program. I am trying to add a button widget on a button click.
But whenever I try to cast the ui->frame->layout() to QHBoxLayout, it crashes.
void MainWindow::onAddWidget()
{
QVBoxLayout *layout = qobject_cast<QVBoxLayout *>(ui->frame->layout());
QString buttonText = tr("Button #%1").arg(layout->count());
QPushButton* button = new QPushButton("buttonText",ui->frame);
layout->insertWidget(0,button);
}
Please help.
I tried to comment out that cast line and added below line
QVBoxLayout *layout = new QVBoxLayout(ui->frame);
Then it worked fine for the 1st button click. Further button clicks gives me this line "QLayout: Attempting to add QLayout "" to QFrame "frame", which already has a layout"
and it doesn't any second widget.

Why does the background color of the button not get changed? I even added the "button.setOpaque(true);" as suggested by others.
enter code here
Jbutton button = new JButton();
button.setBounds(100,100,200,200);
button.setOpaque(true);
button.setBackground(Color.red);
//button.setBorderPainted(false) will work but the button will NOT move anymore
//when button is pressed
JFrame frame = new JFrame();
frame.setSize(400,400);
frame.setVisible(true);
frame.add(button);
Good day all,
I have a simple Dialog started after click button, I post my code:
Dialog dialog;
super();
dialog = new Dialog("Dialog example");
dialog.addText(strFmt("Text to show"));
dialog.addText(strfmt("SecondText to show"));
dialog.run();
I will show a Dialog window loollike this :
It's possible to set the position from code the Text: Text to show ?
For example, if I want to centered position the second text how should I do?
I tried to put blanks in the code:
dialog.addText(strfmt(" Text to show"));
But nothing changes, and this I think not good method.
I saw any suggestions on Web but or I do not use well or is not suitable for me: Example-suggestions.
Exist a method to do what I want?
Thanks for help,
enjoy!
You can center the text using the form control:
Dialog dialog = new Dialog("Dialog example");
DialogText t1 = dialog.addText(strFmt("Text to show"));
DialogText t2 = dialog.addText(strfmt("SecondText to show"));
FormStaticTextControl c1 = t1.control();
c1.widthMode(FormWidth::ColumnWidth);
c1.alignment(FormAlignment::Center);
dialog.run();
The first control is now centered (to the surrounding group).
You have to give it ColumnWidth, otherwise the control would have the minimum size and the centering would have no effect.
Here's the deal, im trying to create a popup window that uses a dynamic text,
when the text is too large i would like to cap the height of the window and
use a scrollbar instead to navigate through it but it does not seems to be
working.
code:
final Dialog dialog = new Dialog();
dialog.setMessage(direttivaDescription);
dialog.setOverflow(Overflow.AUTO);
dialog.setWidth(600);
dialog.setHeight(50);
dialog.setIcon(someIcon);
dialog.setButtons(new Button("OK"));
dialog.addButtonClickHandler(new ButtonClickHandler() {
public void onButtonClick(ButtonClickEvent event) {
dialog.hide();
}
});
dialog.draw();
If the text is too large the window height will be resized accordingly. The funny
part is that setWidth method seems to be working just fine.
You need a container such as HLayout, VLayout, DynamicForm etc. where you can add the message in it then finally add the container in the Dialog.
Sample code:
VLayout vLayout=new VLayout();
vLayout.addMember(new Label(message));
vLayout.setOverflow(Overflow.AUTO);
vLayout.setWidth100();
...
dialog.addItem(vLayout);
dialog.draw();

This is related to my question posted here:
How to make dialog elments collapsible?
Another developer has added two groups to the dialog that is displayed when creating a payment proposal (CustVendPaymJournal_Vend Class) and the "Ok" and "Cancel" buttons are no longer displayed on smaller resolutions (1024x768).
To overcome this I am trying to group some dialog elements in DialogTabPage tabs. However I haven't had any success in my attempts.
This is what I have in the first couple lines of code in the dialog() method for CustVendCreatePaymJournal_Vend
public Object dialog()
{
LedgerJournalType ledgerJournalType;
DialogTabPage tab;
super();
tab = dialog.addTabPage("First tab");
}
I keep on receiving this error anywhere I try to add a tab in the dialog. I have tried to put it on CustVendPaymJournal (from which CustVendPaymJournal_Vend is inherited) also, but to no avail.
DialogTabPage object does not have method 'frameType'.
Try:
dialog = super();
tab = dialog.addTabPage("First tab");
I have a TextField form inside a window. Created with UiBinding. Next to the TextField is a button. I wanted to know if it was possible to create a new TextField widget when that button was pressed using UiBinder?
This is what I have:
Window class:
#UiField
TextField text;
#UiField
HorizontalPanel hPanel;
....
#UiHandler("addText")
public void onClick(SelectEvent event){
hPanel.add(text);
}
My UiBinder file:
<gxt:Window ...(generic setup)...>
<g:VerticalPanel>
<gxt:FramedPanel>
<container:VericalLayoutContainer>
<container:child>
<g:HorizontalPanel ui:field="hPanel">
<form:FieldLabel text="Text">
<form:Widget>
<form:TextField ui:field="text"/>
</form:Widget>
</form:FieldLabel>
<button:TextButton ui:field="addText"/>
</g:HorizontalPanel>
</container:child>
</container:VericalLayoutContainer>
</gxt:FramedPanel>
</g:VerticalPanel>
</gxt:Window>
When I click the button it all it does is move the button from the right side of the text field to the left. I have more textfields in the window so I played around to see what it was really doing. It's taking that field and just moving it next to the button.
Is there a way I can create a new TextField underneath the original?
Probably LazyDomElement will help you.
