PushButton leaves traces?

[mmankows]

I have problem with PushButton relocation:

This is the code:
handler pbTesting.onselect() {
pbTesting.visible = false;

pbTesting.x = pbTesting.x + 4;
pbTesting.y = pbTesting.y + 4;

pbTesting.visible = true;
}

When button is moved the old lines do not get erased.
What should I do?

Setting visible to false on a pushbutton does not erase the border of the control - this is either a bug in the OS or a very interesting and hard to explain "feature" of the OS. In the next version of OrbForms, calling UIForm.redraw() would fix this. In the current version, you will need to manually erase the square around the button.

This problem affects only push button. The regular button is fine.

What is the simplest way to do it?

Use Draw.rect to draw a background-colored rectangle 1 pixel larger than the push button on each side.

Any approximate date on the next release?

I can follow the advice to hide the border, but that doesn't seem to leave me a way to erase the rectangle when I want to show the buttons again.

I tried placing a borderless button on top of the push buttons and showing or hiding it, but that doesn't work.

UIForm.redraw was actually implemented long ago (as this thread is from 2004).

I tried the redraw. It has no effect.

I have coded the following:

pushButton.visible = false;
frmEdit.redraw(0);

It works just the same without the redraw. It simply clears the text.

What am I missing?

Is there something else that needs to be done?

try fmrEdit.redraw(0x800) for better effect

[dlinder]

I don't understand what the purpose is for the integer parameter. I know the help says it can be checked through the event objects code property, but I have no idea why I'd do that.

I've tried any number of different values in the code parameter and none of them (the 0x800 included), have any effect on removing the border from the push buttons.

I'm missing something very obvious here, but I just can't see it.

I was trying to hide the push buttons using a the draw.rect function, and it wasn't doing anything.

Just as a test, I tried to draw a rectangle over the whole screen in the onload and ondraw handlers. It didn't do anything.

I copied code I found on the board. It did nothing.

Below is the code that I found on the board and modified.
Below that is code from the board.

Why doesn't this work?

handler frmVehicle.onopen() {
Draw draw;

draw.attachForm(frmVehicle);
draw.begin;
draw.fg(255);
draw.rect(clrFG, 0, 0, 160, 160, 0);
draw.end;
}

handler mainForm.onopen() {
Draw draw;

draw.attachForm(this);
draw.begin();
draw.fg(255);
draw.rect(clrFG, 0, 0, 160, 160, 0);
draw.end();
}

Drawing in the onopen handler has no effect, since the form itself has not been drawn yet. When running OrbFormsRT-debug.prc, you will get errors when you attempt to do this.

If you set the visible property to false in the onopen handler, the control should not be drawn in the first place.

The problem was that the draw doesn't work on my emulator.

It works fine on my Palm.

Sorry, and thanks.
