PCL CheckBox.Width() == wrong width

[NKV]

Hi Juan,
Add to SandBox one code:

Code: [Select]

Console().WriteLn( String( ParameterThree_CheckBox.Width() ) );
I see result in Console "640".
It's bug or not? And how to get real size of CheckBox ?

Best regards,
Nikolay.

Hi Nikolay,

how to get real size of CheckBox ?

If you refer to the size of the checkbox square, the answer is "you cannot". The size of a control is style- and platform-dependent; there is no (portable) way to predict it.

The 640 pixels reported probably refer to a CheckBox control that has been stretched into a Sizer, and if the control has a nonempty Text() property then the reported Width() includes it. There is no bug AFAIK.

What are you exactly trying to do (something nonportable, I guess!) ?

I want add to GUI a CheckBox to NumericControl. Between Label and NumericEdit.

add to GUI a CheckBox to NumericControl. Between Label and NumericEdit

Define a CheckBox control with an empty Text() (it is already empty by default) and insert it at the right place in NumericControl::sizer. That should work reasonably well on all platforms, but cross your fingers to have it working properly on Mac OS X:

NumericControl foo;
CheckBox bar;
foo.sizer.Insert( 1, bar ); // index one is between label and edit

If instead of NumericControl it were NumericEdit, an additional stretching space woud be required at the end of NumericEdit::sizer:

NumericEdit foo;
CheckBox bar;
foo.sizer.Insert( 1, bar ); // index one is between label and edit
foo.sizer.AddStretch(); // force CheckBox to occupy the minimum possible space

In the case of NumericControl this isn't necessary because NumericControl::slider already has a 100% stretching factor.
