Description

Hi,

I need a way to set the text formatting option (%.2f for instance) for the float value in WSpinBox.

Currently WSpinBox::setValue uses :

setText(WT_USTRING::fromUTF8(boost::lexical_cast<std::string>(value)));

This leads to many unwanted 0s after the last significant digit and this also overwrites the arrows (see alpha value of 1.7000000 in attached snapshot)

As a work-around, i call setText again in the signal callback. However, one can see the text flickering due to 2 consecutive updates.

Regards

Christophe

Hi Pieter,

snprintf in formatFloat does not compile on Windows :

wt\src\web\Utils.C(519) : error C3861: 'snprintf': identifier not found

There is also a warning in the same file :

wt\src\web\Utils.C(492) : warning C4244: 'initializing' : conversion from 'std::streamoff' to 'int', possible loss of data

Hi Pieter,

After patching the code, i have done a test. It does not seem to work.

formatFloat is never called when i click on on the arrows.

I have tried on both firefox and chrome.

the only change i have done is calling setFormat("%.2f")

Regards

Christophe

Christophe, you're right (for the record!). To be dealt with together with #727

I've split the API into WSpinBox and WDoubleSpinBox, and the formatting options have changed. There is now setDecimals(), setSuffix() and setPrefix().
