Libgdx Label: multiline text height

Question

I did a little test on LibGdx, on the Multi-Line Label, it seems that I can not get the wrapped line height. Below is the code. Theoretically, the height for aLebel should be> bLabel. But the result looks the same.

the code:

aLabel.setText("this is a super long long long text that need wrapping."); // line wrapped into 3 lines
aLabel.setWrap(true);
aLabel.setWidth(470);
doLog("aLabel.getHeight(): " + aLabel.getHeight());

bLabel.setText("this is short."); // unwrapped line
bLabel.setWrap(true);
bLabel.setWidth(470);
doLog("bLabel.getHeight(): " + bLabel.getHeight());

result:

aLabel.getHeight(): 45.0
bLabel.getHeight(): 45.0

Does anyone have any ideas how to get the actual multi-line growth in LibGdx? Thanks in advance.

. , , , .

public Label createLabel() {
    // Create label and set wrap
    Label label = new Label("Some long string here...", skin);
    label.setWrap(true);

    // Pack label
    label.pack(); // This might not be necessary, unless you're changing other attributes such as font scale.

    // Manual sizing
    label.setWidth(textWidth); // Set the width directly
    label.pack(); // Label calculates it height here, but resets width to 0 (bug?)
    label.setWidth(textWidth); // Set width again

    return label;
}

Label label = new Label("Example", new Label.LabelStyle(font, Color.WHITE));
label.setWrap(true);

Table table = new Table();
table.add(label).width(WITH);

Answer 4

The packet size of the widget corresponds to the size of the pref, nothing more. The width of the width of the label with the wrapper is 0.

Label label = new Label(...);
label.setWrap(true);
label.setWidth(123);
label.setHeight(label.getPrefHeight());
