Strange Button behavior
« Thread started on: Nov 2nd, 2016, 5:36pm » |

When I run this program fragment in LBB the "Get Student" button behaves oddly.
Does the button text 'waver' when you run the program?
r.m.
Code:
nomainwin
WindowWidth = DisplayWidth : WindowHeight = DisplayHeight
BackgroundColor$ = "cyan"
Button #student.btn6, "Get Student", [getStudentFile], UL, 100,50
Button #student.btn7, "Save Student", [saveStudent], UL, 220,50
Button #student.btn8, "Delete Student", [studentDelete], UL, 350,50
statictext #student.statictext1, "Last Name", 30, 120, 85, 20
textbox #student.lname, 20, 140, 140, 25
statictext #student.statictext2, "First Name", 180, 120, 99, 20
textbox #student.fname, 180, 140, 140, 25
statictext #student.statictext4, "Initial", 345, 120, 70, 20
textbox #student.initial, 340, 140, 40, 25
Stylebits #student.initial, _ES_UPPERCASE, 0, 0, 0
statictext #student.statictext5, "Gender", 395, 120, 60, 20
textbox #student.gender, 400, 140, 30, 25
Stylebits #student.gender, _ES_UPPERCASE, 0, 0, 0
statictext #student.statictext6, "Date of Birth", 470, 100, 60, 40
textbox #student.dob, 460, 140, 60, 25
Stylebits #student.dob, _ES_NUMBER, 0, 0, 0
statictext #student.statictext7, "Spec Needs", 555, 100, 60, 40
textbox #student.special, 550, 140, 70, 25
statictext #student.statictext1, "Address", 30, 190, 85, 20
textbox #student.address, 20, 210, 220, 25
statictext #student.statictext2, "City", 270, 190, 99, 20
textbox #student.city, 260, 210, 140, 25
statictext #student.statictext2, "State", 420, 190, 50, 20
textbox #student.state, 420, 210, 30, 25
Stylebits #student.state, _ES_UPPERCASE, 0, 0, 0
statictext #student.statictext3, "Zip Code", 470, 190, 95, 20
textbox #student.zip, 470, 210, 60, 25
Stylebits #student.zip, _ES_NUMBER, 0, 0, 0
statictext #student.statictext7, "Phone", 560, 190, 60, 20
textbox #student.phone, 550, 210, 90, 25
Stylebits #student.phone, _ES_NUMBER, 0, 0, 0
open "Student File Maintenance" for window as #student
#student, "font ms_sans_serif 10"
#student, "trapclose [studentEnd]"
wait
[studentEnd]
close #student
end

I don't see problem. Or cannot understand from description what a problem is.
I see button pre-selected, that's all.

I don't see anything "odd" here. What am I supposed to be looking for?

This is what he is seeing. The text seems to morph for some reason. My program does it but none of my customers has mentioned it as a problem.

I've no idea whether it has any connection (since I can't reproduce the effect here I can't test it) but there's a bug in the OP's code because the statictext2 extension is used multiple times:
Code: statictext #student.statictext2, "First Name", 180, 120, 99, 20
statictext #student.statictext2, "City", 270, 190, 99, 20
statictext #student.statictext2, "State", 420, 190, 50, 20
Generally it's better not to use an extension with STATICTEXT at all (since if it's 'static' you should never have to reference it after the window is created).

No connection, I stripped it down to just the bare minimum and it still does it. I did notice it only does it to the first declared button, IE switching their order in the original code changes which one "morphs'
Code: nomainwin
Button #student.btn6, "Get Student", [getStudentFile], UL, 100,50
open "Student File Maintenance" for window as #student
#student, "font Microsoft_Sans_Serif 10"
#student, "trapclose [studentEnd]"
wait
[studentEnd]
close #student
end |

No problem. Like I said, none of my customers have mentioned it. Perhaps they don't see it on their system either?
FWIW I am on Windows 7 with Aero enabled.

If you step through the code in the debugger, does it change the button font instantly when it get to the font command on your system? On mine you can see it changing over about a 1 second period.

Yes, it changes instantly. What happens if you explicitly set the button font:
Code: Button #student.btn6, "Get Student", [getStudentFile], UL, 100,50
open "Student File Maintenance" for window as #student
#student "font Microsoft_Sans_Serif 10"
#student.btn6 "font Microsoft_Sans_Serif 10"
#student "trapclose [studentEnd]"
wait

I have found two more programs with the same behavior.
In these cases, there is only one button in the window.
I do not see any failure of the buttons to work as intended.
I am running LBB under Windows 7.

Still does it. You missed the "!" in your button font command.

I wonder if Windows 7 is the common factor. I'll try to run up a Windows 7 machine and test on that.

I have found another instance, this time in a dialog window.
I can't prove it, but I think this is a recent thing - I don't remember it happening, say, last year.

It has been doing it since I changed from LB to LBB around the end of 2013
