I have a GUI which is loaded (with OpenChild) when the user taps on a field on the previous screen (enter field event). On the second GUI there is just one text field visible where the user can enter the quantity for an article.

At the moment if the user needs to change the existing value, he needs to clear first the value and enters the new one using the displayed numerical keyboard.

I would to optimize this. I already tried to set the flags on the text field
--automatic erase
-- with selection in read only

But none of them worked.

Is it somehow possible to call native ObjC code to select all text of that field?

Hi Thomas

did you try to play with the ..cursor and ..cursorEnd properties ?

Normally, by setting them to 0 and 1000 in the entry code of the field,
you should have the whole thing selected

Best regards

Hi Fabrice

thanks for the hint, but in Version 19 the property Cursor... CursorEnd... is not allowed for iOS.

Maybe this comes with Version 20, when it is available in English too.

In the meanwhile I will use this native iOS solution:

In entry of Field call
selectText(Handle(EDT_EnterText))

which is implemented as ObjC function

#import <UIKit/UIKit.h>

void selectText(void* currentView)
{
UIView *tmpView = (UIView*) currentView;
UITextField *iTextField;
for (id object in [tmpView subviews] ) {
if ( [NSStringFromClass([object class]) isEqualToString: @"CIOSCustomTextField"]) {
iTextField = object;
}
}
[iTextField selectAll:nil];
}

Regards
Thomas
