Repositioning the window

[WhoAteDaCake]

Hi, I looking at the code, I assumed that setting "left" and "top" properties of the root widget should move the window, but after some print statements in display.c, I've noticed that the code on line 504:

if (Widget_CheckStyleValid(widget, key_top) &&
	  Widget_CheckStyleValid(widget, key_left)) {

doesn't evaluate to true, even though I've changed the code in helloworld.c

int main(int argc, char **argv)
{
	LCUI_Widget root, pack, btn;

	LCUI_Init();
	root = LCUIWidget_GetRoot();
	pack = LCUIBuilder_LoadFile("helloworld.xml");
	if (!pack) {
		return -1;
	}
	Widget_SetStyleString(root, "top", "100px");
	Widget_SetStyleString(root, "left", "100px");
	
	Widget_SetStyleString(root, "width", "100px");
	Widget_SetStyleString(root, "height", "100px");


	Widget_Append(root, pack);
	Widget_Unwrap(pack);
	btn = LCUIWidget_GetById("btn");
	Widget_BindEvent(btn, "click", OnBtnClick, NULL, NULL);
	return LCUI_Main();
}

Is there a different function I'm supposed to use? I'm sorry if It's documented somewhere and I couldn't find it

So it seems that LCUIDisplay_BindSurface happens before the styles get applied, which is why it seems to be set to 0

Ended up doing a bit of a hacky workaround, to move the window after it's been resized once, I'll move it and then ignore the remaining events.

#include <LCUI_Build.h>
#include <LCUI/LCUI.h>
#include <LCUI/gui/widget.h>
#include <LCUI/gui/builder.h>
#include <LCUI/gui/widget/textview.h>
#include <LCUI/gui/widget/textedit.h>
#include <stdio.h>
#include <LCUI/display.h>

static void OnBtnClick(LCUI_Widget self, LCUI_WidgetEvent e, void *arg)
{
	wchar_t str[256];
	LCUI_Widget edit = LCUIWidget_GetById("edit");
	LCUI_Widget txt = LCUIWidget_GetById("text-hello");

	TextEdit_GetTextW(edit, 0, 255, str);
	TextView_SetTextW(txt, str);
}

// Only care to run this once, so after resize is updated
// we'll never move again
static void OnReady(LCUI_Event e, void *arg) {
	int* moved = (int *) e->data;
	if (*moved == 1) {
		return;
	}
	*moved = 1;
	LCUI_Widget root = LCUIWidget_GetRoot();
	Surface_Move(LCUIDisplay_GetSurfaceOwner(root), 0, 0);
}

int main(int argc, char **argv)
{
	LCUI_Widget root, pack, btn;

	LCUI_Init();
	root = LCUIWidget_GetRoot();
	pack = LCUIBuilder_LoadFile("helloworld.xml");
	if (!pack) {
		return -1;
	}
	Widget_AddClass(root, "test_class");
	
	Widget_SetStyleString(root, "width", "100px");
	Widget_SetStyleString(root, "height", "100px");

	Widget_Append(root, pack);
	Widget_Unwrap(pack);
	btn = LCUIWidget_GetById("btn");
	Widget_BindEvent(btn, "click", OnBtnClick, NULL, NULL);
	// SelectionClear
	int moved = 0;
	LCUIDisplay_BindEvent(LCUI_DEVENT_RESIZE, OnReady, NULL, &moved, NULL);
	return LCUI_Main();
}
